DETAILED DESCRIPTION

0028In some implementations, a medical device can record compliance information that indicates occurrences of treatments performed using the medical device. For example, the compliance information can indicate days and/or times that a patient has performed treatments using the medical device. The compliance information can also indicate a degree to which a patient has complied with a particular treatment regimen. The compliance information can be collected at a server system, and the information can be accessed by multiple parties. The level of access that a party receives can be limited based on the party's relationship to the patient. The server system can receive, store, and provide access to compliance information from multiple medical devices operated by different patients. The medical device can also record errors in the operation of the medical device, send the errors to a server system, and receive service information to address the errors.

0029In addition, or as an alternative, to the above-mentioned features, the medical device can be provided in a deactivated state, and treatment using the medical device can be disallowed until the device is activated by an enabling device. The enabling device can transmit an activation code to the medical device over a wireless communication link. In response to the activation code, the medical device permits treatments to be performed. The enabling device can be limited to performing a number of activations of medical devices specified by a server system. The server system can monitors inventory levels for a sales representative associated with the enabling device, and can send authorization codes to the enabling device to adjust the number of medical device activations that the enabling device can perform.

0030Some implementations of the medical device may provide the following additional advantages. Compliance information may be collected and sent to a server system. Security measures can be implemented so that insurance companies, physicians, and caregivers can receive access to the compliance information based on their relationship to the patient. The server system may receive information about errors that occur during operation of the medical device, and the server system may send service information to address the errors.

0031Some implementations of the medical device may provide the following additional advantages. Medical devices can be maintained in a deactivated state until activated in a controlled process, reducing incentive for theft and misuse. The ability of activation or enabling devices to activate medical devices or to authorize medical treatments can be controlled. The number of medical device activations that can be performed by a device can be limited to an inventory associated with the device.

0032Referring to <figref idref="f0001">Fig. 1</figref>, a patient is shown using a medical device 10 that includes a treatment module for applying a treatment to the patient. The medical device 10 is a portable ultrasonic treatment device that is equipped to provide purchasable treatments. The treatment module may include, for example, one or more ultrasound transducers 16 and at least one driver circuit coupled to the ultrasound transducers 16.

0033The medical device 10 can include a control unit 12 that controls the operation of the transducers 16. The control unit 12 can include the transducer driver circuit. The medical device 10 can also include cables 18 that can carry power, data, and control signals between the control unit 12 and the transducers 16.

0034The medical device 10 can include a placement module 14 that couples the transducers at a location of the patient's body where treatment is needed, for example, over a fractured bone or next to damaged connective tissue. The placement module 14 can include a band, sleeve, applicator, or other connector to fasten the one or more transducers to a treatment site. An ultrasound conducting gel 20 can be applied to the skin of the patient to enable the ultrasound to propagate effectively to the patient's tissue.

0035The medical device 10 can use low intensity, high-frequency acoustic energy (ultrasound) to treat injuries, defects, or pathologies. For instance, the ultrasonic treatment device can be designed to treat injuries, defects, or pathologies of bones or connective tissue, and, in some instances, can increase cellular level activity that leads to healing of ischaemic or grafted tissue. The medical device 10 may be used as an adjunct to surgical repair, in order to speed healing, or in some cases can be used alone to heal tissue injuries without surgery (e.g., for degenerative diseases such as osteoarthritis, tendonosis, and tendonitis). The medical device 10 can be suitable for use in treatment of bone fractures and/or connective tissues associated with joints, such as those in the hand, foot, wrist, ankle, knee, elbow, hip, shoulder, back, and neck.

0036For example, following surgery, the medical device 10 can be applied non-invasively to the outside of the body (e.g., coupled to the skin with coupling media, such as a gel) in the region of the repaired tissue. The medical device 10 can be operated to transmit ultrasound (for example, in the form of pulses) into the tissue in need of treatment, or at the interface with the uninjured tissues. Exposure to the ultrasound can stimulate a faster, better quality repair of the tissue. At a bone interface, the ultrasound can also stimulate bone repair and bone ingrowth into repair or graft tissue. This can give rise to a faster, stronger repair and improved integration of the interface between, for example, tendon, ligament, and bone. The ultrasonic treatment device may also be used to non-invasively treat pathologies of connective tissues, such as osteoarthritis, ligament and tendon conditions, without the need for a surgical procedure.

0037Referring to <figref idref="f0002">Fig. 2</figref>, the control unit 12 of the medical device 10 can include a processing device 50 that executes instructions stored on a storage device 52. The processing device 50 can include one or more processing devices. The storage device 52 can include one or more storage devices, one or more of which may be removable. The control unit 12 can also include a driver circuit 54, a user interface module 60, a communication module 64, and a power supply 68.

0038By executing the instructions stored on the storage device 52, the processing device 50 can, for example, control a treatment module (for example, driver circuit 54 and transducers 16) to apply a medical treatment in response to user input. Applying the treatment can include controlling the driver circuit 54 to produce ultrasound with therapeutic properties. Controlling the driver circuit 54 to produce ultrasound can include activating the driver circuit 54, for example, supplying power to the driver circuit 54, sending control signals to the driver circuit 54, or causing the driver circuit 54 to produce a particular output.

0039If the medical device 10 is in a disabled state, or if treatment with the medical device 10 is not authorized, the processing device 50 can control the treatment module such that the treatment is not applied. For example, the processing device 50 can control the driver circuit 54 such that ultrasound with therapeutic properties is not produced. Controlling the driver circuit to not apply treatment can include not activating the driver circuit 54, deactivating the driver circuit 54, setting the output of the driver circuit 54 (for example, setting the amplitude to zero), and/or otherwise limiting or preventing treatment. The processing device 50 can also be configured to control other components described below, for example using instructions stored on the storage device 52.

0040The storage device 52 can store a device identifier, such as a serial number, that identifies the particular medical device 10. The device identifier can uniquely identify the medical device 10 and distinguish it from all other ultrasonic treatment devices, even those of the same type or model.

0041The driver circuit 54 can be configured to send drive signals that cause the transducers 16 to generate ultrasound with therapeutic properties. The driver circuit 54 can include a signal generator 56 that generates a signal and a transducer driver 58 that drives the transducers 16 according to the generated signal. In some implementations, the ultrasound generated by the transducers 16 can include low intensity ultrasound (for example, 100mW/cm² or less) having a frequency ranging between about 1 and 2 MHz, more particularly about 1.5 MHz. The ultrasound can be pulsed, with a pulse width ranging from about 10 to 2,000 microseconds, more particularly about 200 microseconds, with a repetition frequency ranging from about 100Hz to about 10KHz, more particularly about 1 KHz.

0042The user interface module 60 can provide information to the patient and enable treatment to be initiated. The user interface module 60 may include one or more input devices or controls, for example, buttons, a keypad, or a touch-sensitive screen. The user interface module 60 may be used by a patient or other person, for example, to enter user input that indicates that a treatment should be administered by the medical device. When the processing device 50 determines that treatment is not authorized, the processing device 50 can provide an indication to the patient on the user interface module 60 that more treatments need to be purchased.

0043The user interface module 60 may also include one or more output devices, for example a screen, a liquid crystal display, or lights. For example, the user interface module 60 can include a screen 72, for example, a liquid crystal display (LCD), a thin-film transistor (TFT) display, a field sequential display, or an organic light-emitting diode (OLED) display. The user interface module 60 can also include light-emitting diodes (LEDs) and other indicators. The user interface module 60 may include a speaker or other device that can produce sound (not shown), or other output devices. The user interface module 60 may also include input capabilities or input devices (not shown), for example, buttons, one or more keypads, and other controls. The screen 72 may be touch-sensitive to receive input from a user. The user interface module 60 can also include an interface to access a removable storage medium, such as a subscriber identity module (SIM) card, a Secure Digital (SD) card, or other types of removable storage media.

0044The communication module 64 can be configured to send compliance information to a remote system and/or receive information that affects the operation of the medical device 10. In some implementations, the processing device 50 is configured to receive an activation code or other activation data through the communication module 64 and to store the received activation code in the storage device 52. The communication module 64 can enable communication with a server system, client system, or other computer system over a wired or wireless connection. The communication module 64 may enable a communication link that is wired or wireless. The communication module may enable communication over, for example, Ethernet, Universal Serial Bus, 502.11, Bluetooth, Zigbee, cellular networks, and other communication links. In one implementation, the communication module 64 can include a cellular transceiver 66 to receive and/or transmit information over a cellular network. The communication module 64 may also enable communication through multiple communication links.

0045A power supply 68 can provide power to the components of the medical device 10, including the driver circuit 54, the processing device 50, the storage device 52, the payment module 62, the communication module 64, and the user interface module 60. The power supply 68 can include a battery that is integrated into the control unit 12 or is removable. The battery can be primary battery or a rechargeable battery, and the power supply 68 can include a detachable power adapter that can charge a rechargeable battery.

0046When a user performs treatment using the medical device 10, the medical device 10 can collect and store compliance information. Collecting compliance information can include recording information about use of the medical device 10, for example, recording information that indicates occurrences of medical treatments using the medical device 10. Compliance information can include a number of treatments provided by the medical device 10, a date and time that a treatment was provided by the medical device 10, and/or a duration that a treatment was provided by the medical device 10. Information about multiple uses or treatments with the medical device 10 can be collected.

0047A treatment regimen that identifies a prescribed use of the medical device 10 can be identified, and data that indicates the treatment regimen can be stored on the storage device 52. For example, the treatment regimen may be entered on the device after the health condition has been diagnosed or after the medical device 10 has been prescribed to the patient. Information about a treatment regimen may be entered on the medical device 10 or received from a network, which may include a cellular network. The information about the recorded use of the medical device 10 can be compared to the information about the prescribed use of the medical. Information indicating the degree that the recorded use matches the prescribed use can be generated, stored on the storage device 52, and communicated to other devices.

0048Compliance information can be stored on the storage device 52, on a removable medium, or both the storage device 52 and a separate removable medium. The compliance information may, but is not required to, include one or more results of a comparison between the recorded use of the medical device 10 and scheduled or planned use of the medical device 10, for example, as indicated by treatment regimen of the patient.

0049Referring to <figref idref="f0003">Fig. 3</figref>, an example of a system 200 for collecting compliance information includes the medical device 10, a server system 202, and a third-party system, all connected by a network 208. The medical device 10 and the server system 202 may, additionally or alternatively, communicate through a cellular network 209.

0050The medical device 10 can record use of the medical device 10, for example, by recording the date, time, and duration that treatment occurs using the medical device 10. The recorded use of the medical device 10 can be collected as compliance information 210. For example, the medical device 10 can collect information about multiple treatments performed or multiple aspects of treatment.

0051As described above, in some implementations, the medical device 10 may receive information about the treatment regimen for the patient. For example, the treatment regimen may be entered on the device after the health condition has been diagnosed or after the medical device 10 has been prescribed to the patient. The compliance information 210 may, but is not required to, include one or more results of a comparison between the recorded use of the medical device 10 and the treatment regimen of the patient.

0052To distinguish the medical device 10 from other medical devices 10, the medical device 10 may store a device identifier 212 that enables the medical device 10 to be identified. For example, the device identifier 212 may uniquely identify a particular medical device 10.

0053The medical device 10 can send the compliance information 210 to the server system 202. Compliance information 210 can be sent automatically, for example, after a predefined number of treatments are performed, after a particular amount of time has elapsed, or after a treatment regimen has been completed. The medical device 10 may send the compliance information 210 over the network 208. Additionally, or alternatively, medical device 10 may send the compliance information 210 over a cellular network 209. The medical device 10 can also send the device identifier 212 to the server system 202 with the compliance information 210, enabling the server system 202 to associate the compliance information 210 with the particular device. In addition to a device identifier, or alternatively, the medical device 10 may send a patient identifier with the compliance information 210.

0054The server system 202 can be configured to receive the compliance information 210 and the device identifier 212 from the medical device 10. The server system 202 can determine a patient identifier using the device identifier 212. For example, the server system 202 may store records that associate device identifiers 212 for multiple medical devices 10 with patient identifiers. The server system 202 can compare the received device identifier 212 to stored device identifiers to determine a patient identifier and identify the patient that uses the medical device 10. The server system can store the compliance information 210 in association with the determined patient identifier.

0055The server system 202 can be configured to receive compliance information from multiple medical devices 10 operated by different patients. For example, the server system 202 may include a compliance database of many patients and information about the prescriptions and medical devices 10 that correspond to each patient. The server system 202 can receive and record compliance information from each or any of patients or medical devices 10 described in the compliance database. The server system 202 can add information about additional patients and medical devices 10 to the compliance database records.

0056The server system 202 can provide access to the stored compliance information 210 to one or more parties that have a relationship with the patient. For example, an insurance company for the patient may use the compliance information 210 to determine whether the patient is using the medical device 10 that the insurance company paid for. A physician or a caregiver for the patient may use compliance information 210 to determine if the patient is complying with a treatment regimen that has been prescribed. To obtain compliance information 210 for the patient, a third-party system 204 may submit an inquiry requesting the compliance information 210 to the server system 202. For example, the inquiry 216 may include one or more patient identifiers to identify one or more patients. The server system 202 can provide access to the compliance information 210 for one or more users in response to receiving the inquiry from the third-party system 204.

0057Because the server system 202 can store compliance information about multiple patients and multiple medical devices 10, the server system 202 can provide aggregate information about multiple patients and medical devices 10. For example, the server system 202 may provide an insurance provider with a summary of the treatments performed for all patients covered by the insurance provider. As another example, a physician may receive compliance information for each of his patients from the server system 202, without being required to interface with each of the prescribed medical devices 10 individually. Summaries, reports, graphs, and comparisons can be provided based on compliance data for multiple patients, including, for example, information about a set or subset of patients. For example, the compliance of patients that have a particular health condition can be provided.

0058Access to the compliance information 210 can be limited based on the relationship of the third party to the patient. The server system 202 can store records that associate various third parties with various patients. The third party system 204 may be required to be authenticated or comply with other security measures before access to compliance information 210 is provided. Access to compliance information 210 can also be limited by restricting the quantity or detail of information available. For example, one third party may receive more detailed compliance information 210 than a different third party may receive for the same patient. For example, an insurance company for the patient may be provided access only to the number of treatments performed with the medical device 10, but the physician of the patient may be provided access to the particular dates and times that treatments occurred in addition to the total number of treatments.

0059The medical device 10 can also detect and record information about errors of the medical device 10. During treatment or during other operation of the medical device 10, one or more errors may occur. The medical device can store information about the errors as error information 214, and can send the error information 214 to the server system 202 with the device identifier 212. In one implementation, error information 214 can be sent soon after the error is detected. Examples of errors that can be detected, and for which information can be recorded and sent, include a gel error indicating that there is insufficient ultrasound conductive gel on a transducer, a battery error that indicates that remaining power of the battery is low, and a connectivity error that indicates that a wire to a transducer is disconnected or broken.

0060The server system 202 can be configured to receive the error information 214 and the device identifier 212. The server system 202 can store the received error information 214 and can associate error information 214 with the device identifier 212. The received error information 214 may quickly and accurately indicate which medical devices 10 and which types of medical devices 10 experience errors and at what frequency errors occur.

0061The received error information may also enable the server system 202 to provide information to the medical device 10 to address the errors. For example, the server system 202 may use error information 214 to determine a possible cause of an error. The server system 202 may select service information 218 that addresses the error. For example, the server system 202 may select information to store on the medical device 10, which may include information to restore or replace outdated or incorrect information. The server system 202 may select control instructions to be executed on the medical device 10, for example, control instructions to clear an error or to reinitialize the medical device 10. The server system 202 can send the selected service information 218 that addresses one or more errors to the medical device 10. The service information 218 can include, for example, software or firmware updates, instructions to the user of the medical device 10, instructions to trained service personnel, and/or control instructions to alter the functioning of the medical device 10 and modules coupled to the medical device 10.

0062The server system 202 can send information including one or more messages 230 to the medical device 10. The messages 230 may be stored on the medical device 10 and displayed to the patient during treatment. The messages 230 can include updated information or additional information to add to messages 230 already stored on the medical device 10. In addition, one or more messages 230 can be provided to instruct the patient how to correct an error of the medical device 10, or to inform the patient that an error has been corrected.

0063Referring to <figref idref="f0004">Fig. 4</figref>, a medical device 10 may collect and send information as illustrated in the process 300. The processing device 50 of the medical device 10 may, for example, execute instructions stored on the storage device 52 to perform the process 300.

0064A driver circuit is controlled to produce ultrasound with therapeutic properties (302).

0065Compliance information is collected (304). Collecting compliance information can include recording information about use of the medical device, for example recording the number of treatments that are performed. Compliance information can include a number of treatments provided by the medical device, a date and/or time that a treatment was provided by the medical device, and/or a duration that a treatment was provided by the medical device. Information about multiple uses or treatments with the medical device can be collected.

0066A treatment regimen that identifies a prescribed use of the medical device can be identified. For example, information about a treatment regimen may be entered on the medical device or received from a network, which may include a cellular network. The information about the recorded use of the medical device can be compared to the information about the prescribed use of the medical. Information indicating the degree that the recorded use matches the prescribed use can be generated and stored as compliance information.

0067A device identifier can be accessed (306). The device identifier can be stored on the medical device. The compliance information can be sent (308). The accessed device identifier can be sent with the compliance information. For example, the compliance information can be sent to a server system configured to receive the compliance information. Compliance information can be sent automatically after a predetermined number of treatments have been performed. Compliance information may be sent using a wireless module, and the wireless module can include a cellular transceiver. For example, compliance information may be sent to a server system over a cellular network using the cellular transceiver. The medical device can include a SIM card that associates a particular telephone number with the medical device.

0068In some implementations, compliance information can additionally or alternatively be stored on a removable data storage device such as an SD card or other memory card. The removable data storage device can be removed from the medical device 10 and coupled to a computer system. The computer system can then transmit the compliance information (with the associated device identifier) to the server system.

0069One or more errors of the medical device can be detected. Information about the detected errors can be sent with the accessed device identifier to a server system. Service information to address the detected errors can be received from the server system.

0070Referring to <figref idref="f0005">Fig. 5</figref>, a server system can process information according to the illustrated process 400. For example, one or more storage devices can store instructions that, when executed by one or more processing devices, cause the server system to perform the process 400.

0071Compliance information can be received (402). For example, compliance information can be received over a network or cellular network from one or more medical devices. Compliance information for multiple medical devices operated by different patients can be received. For example, the server system may be configured to receive compliance information from each of a plurality of patients, and each patient can be associated with at least one of a plurality of medical devices. The compliance information can include a number of treatments provided by a medical device, a date and time that a treatment was provided by the medical device, and/or a duration that a treatment was provided by the medical device. Compliance information can be received for multiple medical devices operated by different patients.

0072A device identifier can be received (404). The device identifier can be received with the compliance information. A patient identifier can be determined (406). For example, the received device identifier can be used to determine the patient identifier. The server system can store records that associate device identifiers with one or more patient identifiers. The recorded device identifiers can be compared to the received device identifier to determine a recorded device identifier that matches the received device identifier.

0073The compliance information can be stored (408). The compliance information can be stored in association with the patient identifier that was determined to correspond to the compliance information. For example, the server system may be configured to store compliance information for each of a plurality of patients, and each patient can be associated with at least one of a plurality of medical devices. Compliance information for each patient can be stored in association with one or more device identifiers and/or patient identifiers.

0074Access to the compliance information can be provided (410). For example, access may be provided to one or more users of the server system. Users may submit an inquiry to the server system, and the inquiry can be associated with a patient identifier. Users can include, for example, one or more of a representative of an insurance provider of the patient, a physician of the patient, and a caregiver for the patient. Access to the compliance information for a particular patient can be provided to the users in response to receiving the inquiry that is associated with the patient identifier for the particular patient. Access to the compliance information can be limited based on the relationship of the user to the patient. For example, a physician of the patient may receive access to only a portion of the compliance information, such as only the number of times the medical device was used. A physician, on the other hand, may receive access to more detailed compliance information, such as the date, time, and duration that the medical device was used.

0075Because compliance information for multiple patients and multiple medical devices can be stored, access to compliance information for multiple patients and multiple medical devices can be provided. For example, compliance information can be provided to a third party for treatment performed by multiple medical devices operated by multiple patients. Users that can receive access to the compliance information can include, for example, one or more caregivers, physicians, and representatives of insurance providers for any of the multiple patients whose compliance information is stored. Access can be provided to compliance information for each of a plurality of patients, where each patient is associated with at least one of a plurality of medical devices. Access to the compliance information for a particular patient can be provided to the users in response to receiving the inquiry that is associated with the patient identifier for the particular patient.

0076Information about one or more errors of the medical device can be received. Based on the information about the errors, service information to address the errors can be selected and transmitted to the medical device. One or more messages for the patient can be transmitted to the medical device.

0077Referring to <figref idref="f0006">Fig. 6</figref>, a process 500 for storing patient information can begin with a physician writing a prescription for a patient for treatment using a medical device (502). To carry out the prescribed treatment, a medical device can be dispensed to the patient (504). The medical device can be authorized at the time the medical device is dispensed or at a later time.

0078Records for the patient and the dispensed medical device can be entered into a database 514 (506). For example, the database 514 may store a patient record 510 that associates a particular medical device or treatment with a particular patient, in the example, a patient named "John Smith." The database 514 may also store a prescription record 512 that indicates the number of treatments that can be purchased for the patient. The number of treatments indicated in a prescription record 512 may be authorized for application by the medical device after payment has been received for the prescribed treatments. For example, the treatments can be enabled after a third-party payer agrees to pay for the treatments or after the patient enters payment at the medical device. The database 514 may also store other records including records that identify patient identifiers and medical device identifiers.

0079The information in the database can be accessed by one or more client devices 518, 520, a server system 522, or other systems. For example, the server system 522 may use the patient record 510 to match payment to a particular medical device or patient. The records stored in the database 514 may also be used to inform a third-party payer or patient of the number of treatments that should be purchased to enable a treatment plan to be carried out.

0080Referring to <figref idref="f0007">Fig. 7</figref>, an inventory tracking and medical device activation system 600 can be used to control the distribution of medical devices 10. The system 600 includes an enabling device 610 that communicates with the medical device 10. The enabling device 610 also communicates with a server 620 over a network 630.

0081Each medical device 10 can be provided to a distributor or physician in a disabled or deactivated state. Because the medical devices 10 are shipped and stored in inventory in an inoperative state, the potential for unauthorized use is very low. For example, the medical device 10 can be provided in a state in which no treatments are authorized. In addition, or as an alternative, the medical device 10 can be provided in a state in which treatments cannot be purchased or authorized, until the medical device 10 is activated and thus made operative by an enabling device. Activation of a medical device can be an event that occurs only once, before an initial use of the medical device. In some implementations, the medical device 10 can be pre-authorized to perform medical treatments, but may nonetheless be limited from performing the authorized medical treatments until activation occurs. Activation of the medical device 10 can thus be separate from authorization of treatment using the medical device 10, which can occur in response to payment or the issuance of a prescription for use of the medical device 10.

0082The enabling device 610 includes the capability to activate medical devices 10. For example, the enabling device 610 can include an activation module including a wireless or wired communication system to transmit activation information. The server 620, however, can limit the enabling device 610. For example, the server 620 can authorize the enabling device 610 to activate only a limited number of medical devices 10. The total number of medical device activations that the enabling device can be performed can be limited (e.g., no more than 10 activations, until further authorization is received). Additionally, or alternatively, the number of activations that can be performed over a particular period of time can be limited (e.g., no more than 10 activations per month). As described in further detail below, the server 620 can limit the number of medical device activations that the enabling device 610 can perform so that, at any given time, the enabling device 610 is authorized to perform a number of medical device activations no greater than the number of medical devices in a particular inventory 613 of a particular sales representative 612. The enabling device 610 is associated with the sales representative 612, and a unique identifier for the enabling device 610 or for the representative 612 associates the enabling device 610 with the inventory 613 of the representative 612.

0083The server 620 tracks the inventories of multiple representatives. The server 620 can identify changes in inventories using information from reliable sources, for example, information that is verifiable or outside the control of the representatives. For example, the server 620 receives information from manufacturers or distributors of medical devices about shipments of products to the representatives.

0084Based on the inventory 613 for the representative 612, the server 620 adjusts the ability of the enabling device 610 to activate medical devices 10. For example, the server 620 authorizes the enabling device 610 to activate as many medical devices 10 as are in the official inventory 613 for the representative 612. For example, when the medical devices 10 are shipped to the representative 612, the server 620 receives information about the shipment 614 from the manufacturer or distributor. In response to determining that the inventory 613 for the representative 612 has increased, the server 620 transmits to the representative's enabling device 610 an authorization code 622 or other authorization data that permits a number of medical device 10 activations corresponding to the size of the shipment 614. If twenty medical devices 10 are shipped to the representative 612, the server 620 sends an authorization code 622 permitting the enabling device 610 to activate up to twenty medical devices 10.

0085When the medical device 10 is purchased or dispensed to a patient, the sales representative 612 can activate the medical device 10 using the enabling device 610. The enabling device 610 communicates with the medical device 10 over a wired link or a wireless link, such as Bluetooth. For example, the enabling device 610 supplies an activation code 624 or other activation data to the medical device 10 that unlocks the functionality of the medical device 10. The enabling device 610 can also supply an authorization code 626 that authorizes a particular number of treatments to be performed with the medical device 10. The activation code 624 and the authorization code 626 can be combined in a single message or code. After the medical device 10 receives the activation code 624, the medical device 10 determines whether the activation code 624 is valid to activate the medical device 10 and/or one or more of its treatment modules. In response to determining that the activation code 624 is valid, the medical device 10 may send an activation confirmation message (not shown) to the enabling device 610 to indicate that activation was successful.

0086After the enabling device 610 activates the medical device 10, the enabling device 610 automatically decreases the number of activations that the enabling device 610 can provide. For example, the number of activations permitted is decreased by one, from twenty to nineteen. The number of activations can be decreased in response to receiving the activation confirmation message from the medical device 10 so that the number is decreased only after successful activation attempts.

0087Once the activations allowed by the authorization code 622 are exhausted, the enabling device 610 is restricted from activating additional medical devices 10. The representative 612 is thus restricted from activating medical devices 10 beyond those legitimately in the representative's inventory 613. When a new shipment of medical devices 10 is sent to the representative 612, the server 620 transmits a new authorization code that permits the enabling device 610 to activate the medical devices 10 in the new shipment.

0088In some implementations, the server 620 can also communicate with the enabling device 610 to reduce the number of activations allowed, for example, if the inventory 613 of the representative 612 decreases due to returning unused medical devices to the manufacturer. Accordingly, the number of activations that can be provided by the enabling device 610 is maintained according to the current inventory 613 of the representative 612.

0089In some implementations, the enabling device 610 sends a message 628 to the server 620 that indicates when an activation of a medical device 10 has occurred, allowing the server 620 to monitor activations. The remaining number of activations currently allowed by the enabling device 610 can be included in the message 628.

0090In some implementations, after the medical device 10 expends all of the treatments authorized by the authorization code 626, a second authorization code can be received to permit additional treatments to be performed. As described above, the second authorization code can be received in response to payment by a patient or a patient's insurance provider. The second authorization code can be received, for example, over the network 630, from the enabling device 610, or from a removable medium.

0091By contrast, in some implementations, the medical device 10 returns to an inoperative, deactivated state after the treatments authorized by the authorization code 626 are exhausted. Thus the medical device 10 must be activated with an activation code from the enabling device 610 before further treatments are permitted.

0092The medical device 10 can be configured to transmit information indicating usage of the medical device 10, including compliance with a treatment regimen, to the enabling device 610 over the same communication link used to receive the activation code. Thus, as part of the exchange, the medical device 10 receives a new activation code from the enabling device 610, and the enabling device 610 receives usage information from the medical device 10. The enabling device 610 can then transmit the usage information to the server 620, with identifiers to identify, for example, the patient, prescription, and medical device 10 associated with the usage information.

0093In some implementations, rather than being enabled by a transmission of an activation code from an enabling device, a medical device can be activated by a code accessed from a removable medium, such as an SD memory card.

0094Referring to <figref idref="f0008">Fig. 8</figref>, the system 600 can also control medical device activations and treatment authorizations based on prescriptions and insurance payment authorizations. For example, the enabling device 610 can be limited to activating a medical device when a valid prescription for the medical device is received, or when an insurance company authorizes payment for a prescribed medical device.

0095The enabling device 610 can be configured to require an authorization code before performing each activation. Each time a medical device is activated, a new authorization code is required. The server 620 provides authorization codes over the network 630. The server 620 can provide an authorization code allowing the activation of a single medical device based on a particular prescription for the medical device. If no prescription is submitted to the server 620, the server 620 does not send an authorization code to the enabling device 610, and the enabling device 610 is unable to activate medical devices.

0096For example, after a physician issues a prescription for treatment using the medical device 10, the prescription can be entered on the enabling device 610, which transmits identifying information 715 identifying the prescription to the server 620. For example, the enabling device 610 transmits a representative identifier and a prescription identifier in the identifying information 715. The identifying information 715 may be additionally or alternatively transmitted by the medical device 10, a physician's computer system, an insurance company computer system, or other system. In some implementations, the identifying information 715 can identify the prescription, the patient receiving the prescription, the doctor or office issuing the prescription, an insurance company for the patient, an insurance policy for the patient, the representative 612, the medical device 10 to be activated, and/or the enabling device 610, and the information can be stored by the server 620.

0097The server 620 verifies the prescription information, for example, by comparing the prescription information to other prescription records or by verifying an authentication signature in the received information. The server 620 can also communicate with another server system 710, such as a server for an insurance company of the patient, to determine whether payment has been authorized for the prescription.

0098If the prescription is determined to be valid, and/or if payment has been authorized, the server 620 transmits an authorization code 720 to the enabling device 610. The authorization code 720 permits the enabling device 610 to activate a single medical device 10 for the patient and prescription that were verified. The enabling device 610 transmits an activation code 724 to the medical device 10. The enabling device 610 also transmits an authorization code 726 to the medical device 10, permitting the medical device 10 to apply the number of treatments indicated in the prescription, or the number of treatments for which payment was authorized by the insurance company.

0099The enabling device 610 can transmit information to the server 620 indicating that the activation of the medical device 10 was performed. Based on the initial identifying information 715 and/or information received subsequent to the activation, the server 620 can record the transaction identifying, for example, the patient, the prescription, the medical device 10, the representative 612, the enabling device 610, and the authorization code 720 associated with the activation.

0100When no prescription is submitted to the server 620, the server 620 does not send an authorization code to the enabling device 610, and the enabling device 610 cannot activate the medical device 10. Similarly, if the prescription information sent to the server 620 is invalid or is not verifiable, or if payment is refused by an insurance provider, the server 620 can withhold the authorization code, disallowing the activation of the medical device 10.

0101In a similar manner, the system 600 can be used to track and/or evaluate passes for unpaid treatments. In some implementations, the enabling device 610 can be authorized to provide a limited number of complimentary medical device activations or treatment authorizations for previously activated medical devices 10. Each time a pass is provided, the enabling device 610 transmits information to the server 620 identifying, for example, the physician, representative 612, medical device 10, and insurance provider associated with the pass. The information may also identify the patient and prescription associated with the pass. The server 620 can thus maintain a database tracking the issuance of complimentary passes for different representatives 612, physicians, and insurance providers.

0102In some implementations, the enabling device 610 can be limited to providing passes when the server 620 provides authorization for each pass individually. For example, the server 620 can evaluate the circumstances of a particular patient and a particular prescription to determine whether the patient qualifies for complimentary or reduced cost treatment.

0103The enabling device 610 transmits a request to the server 620 that indicates the circumstances of the desired pass. The request can indicate, for example, the medical condition to be treated, the identity of the patient, an associated prescription, the patient's income or other financial status, whether and to what degree treatment is covered by insurance, and what insurance provider covers the treatment. The request can also identify the physician, representative 612, enabling device 610, and medical device 10 associated with the request.

0104The server 620 receives and evaluates the request for the pass. For example, the server 620 uses the information in the request to evaluate the patient's medical needs, economic circumstances, and other circumstances to determine whether to authorize the activation and treatment authorization of a medical device for the patient. If the patient's circumstances meet the criteria for complimentary treatment, the server 620 sends an authorization code to the enabling device 610 permitting the enabling device 610 to provide a pass for the particular patient. If the patient does not qualify for a pass, the server system 620 withholds the authorization code necessary to activate a medical device or authorize additional treatments for the medical device. The server 620 can record each request for a pass, each pass granted, and activations and treatments that occur based on the pass.

0105The techniques described above are not limited to any particular hardware or software configuration. Rather, they may be implemented using hardware, software, or a combination of both. The methods and processes described may be implemented as computer programs that are executed on programmable computers comprising at least one processor and at least one data storage system. The programs may be implemented in a high-level programming language and may also be implemented in assembly or other lower level languages, if desired.

0106Any such program will typically be stored on a computer-usable storage medium or device (e.g., CD-ROM, RAM, or magnetic disk). When read into the processor of the computer and executed, the instructions of the program cause the programmable computer to carry out the various operations described above.

0107A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made. For example, the techniques described can be implemented for medical devices that do not produce ultrasound. A medical device can be activated as described above, and compliance information can be transferred and accessed as described above, for medical devices that include treatment modules other than ultrasound treatment modules.

0108Accordingly, other implementations are within the scope of the following claims.
