This is a divisional of Canadian National Phase Patent Application No. 2,651,192 filed on May 16,2007.

TECHNICAL FIELD (0001J The invention pertains to intravascular port access devices, intravascular port cleaning devices, methods ol cleaning an Intravascular port, methods of administering an agent into an intravascular line port, methods of obtaining a blood sample from an Individual, and sots of Intravascular line port caps.

BACKGROUND OF THE INVENTION (0002] Intravenous lines, such as peripheral IV fines and central IV lines, are common Intravenous access methods for administering medicants, nutrien! solutions, blood products, or other substances Into a vein. Arterial lines are used, for example, in monitoring physiological parameters by arterial blood sampling during coronary, intensive or critical care. However, microorganism Intravascular device colonization or infection can occur as a result from a patients* own endogenous flora or from microorganisms introduced from contaminated equipment or other environmental contamination sources. As a result, localized or systemic Infection or septicemia can occur and can be life threatening.

(0003] Introduction of microorganisms into an intravenous line can be initiated or facilitated during handling of a catheter, hub, associated tubing, equipment, or injection ports, especially during manipulation of lines in preparation and during initiation of fluid administration into or withdrawal from the line. Microorganisms present on a surface of an injection port can be Introduced through the port during administration. Microorganisms present on contaminated equipment utilized for administration can be introduced through the port causing colonization or infection. Bacterial growth and/or aggregation in a port or catheter can serve as the nidus for clotting, embolization and/or occlusion of the port or catheter. Further manipulation or administration through the port can facilitate spreatfing of microorganisms within the port, catheter, and lines, and ultimately into the patient's vein/artery and/or surrounding tissue. Accordingly, it would: be advantageous to develop methods and devices for cleaning of external surfaces of

In particular applications devices of the invention can be used for cleaning external surfaces of a intravascular line port followed by cleaning of the port itself and in particular instances cleaning of intravascular lines.

[0035] In other applications devices of the invention can be utilized for administering an agent intravascularly. During these applications, the devices in accordance with the invention can typically be utilized to cleanse external surfaces of

CA 02893151 2015-05-28

WO 2007/137056 PCT/US2007/069015 the port prior to utilizing the device for administering ol an agent intravascularly. In another application devices of the invention can be utilized to obtain a blood sample from an individual. A device in accordance with the invention is typically utilized to cleanse external surfaces of a port prior to utilizing the device to withdraw a sample of blood from the port. The invention also includes methodology for such port cleansing agent administration and blood sampling techniques.

[0036] In one embodiment, the device comprises two components. An example two component device is described with reference to Figs. 1 -5.

[0037] Referring initially to Fig. 1, a port access device 10 comprises a first component 12 at a first end 14 of the device, and a second component 16 at a second end 18 of the device. Second component 16 can have a tab 20 or other extension feature for assisting removal of the second component from the first component. First component 12 has a chamber housing 22 which can be a collapsible housing. First component 12 can also comprise an extension portion 24. Referring to Fig. 2, as depicted device 10 can have second portion 16 insertable within connector portion 24. It is to be understood however that the invention contemplates other configurations wherein second portion 16 fits over or caps extension portion 24. It is also to be understood that the shape and dimension of collapsible housing 22 is but an example with alternative shapes, sizes and configurations contemplated.

[0038] Referring to Fig. 3 such shows an exploded view of the device depicted in Figs. 1 and 2. As illustrated chamber housing 22 of device 10 can house a chamber 23. Connector 24 can comprise a separator 25 having an opening 29 passing therethrough. Connector 24 can further comprise a receiving port 30 for receiving a dispenser 26. Dispenser 26 in turn can comprise a valve portion 28. Second component 16 can comprise a container 21.

[0039] Referring next to Fig. 4, such shows dispenser 26 with valve 28 seated within receiving port 30. As depicted such valve mechanism i3 in the “closed position where contents of chamber 23 are blocked from passing into or through connector 24. Referring next to Fig. 5, application of force upon collapsible housing 22 such as a downward pressure upon a top surface of the housing can be utilized to displace valve device 28 from receiving port 30 as illustrated. Such displacement can allow passage of the contents of chamber 23 into or through connector portion 24.

[0040] As depicted in Fig. 4, second component 16 can contain an applicator material 32. Such applicator material can be for example, a sponge or sponge-type 5

CA 02893151 2015-05-28

WO 2007/137056 PCT/US2007/069015 material. Exemplary sponge-type materials can include but are not limited to polyethylene felt sponge, polyethylene foam sponge, plastic foam sponge and silicon foam sponge.

[0041] Where device 10 is to be utilized for port cleansing applications, container 21 of second component 16 will typically contain a cleansing agent. The cleansing agent can be a disinfecting agent for cleansing external port surfaces. The agent is not limited to a particular cleaning or disinfecting agent and can comprise for example alcohol, preferably contained in an alcohol solution comprising from about 5% to about 99% alcohol. In particular applications the alcohol solution will comprise 25% to 90% alcohol. The sponge-type applicator material can be utilized to assist in containing the cleansing agent and can further assist in applying the agent to external surfaces of the intravascular port. Second component 16 is removably attached to the device 10. For cleansing of the port, removable component 16 is removed from first component 12 and is utilized to contact external port surfaces for cleansing of external portions of an intravascular line port.

[0042] After cleansing of external portions of the port, the first component of the device, which in cleansing/disinfecting applications can be utilized for internal cleansing of the intravascular port, can be reversibly attached to the port to be cleansed. The chamber volume can be for example up to 3.5 ml; a preferred volume range can be from about 1 to about 3 ml. although alternative chamber sizes for smaller or larger volumes are contemplated. The chamber can have appropriate calibration marks relative to the total volume of the chamber. For example, a 3.5 ml. fluid volume chamber can have volume markings every 1 ml, every 0.5 ml, every 0.1 ml, etc. In particular embodiments, the connector portion can have a LEUR-LOK® (Becton, Dickinson and Company Corp., Franklin Lakes NJ) fitting (not shown) for connection to a LEUR-LOK® type port. A cleansing agent can be provided within chamber 23 and can be an antibiotic or an alternative appropriate disinfectant. An exemplary agent can be an alcohol or alcohol solution such as described above relative to the second component container 21. In cleansing applications chamber 22 can alternatively or additionally contain chemical agents including ethylene diamine tretaacetic acid (EDTA) and/or sodium citrate.

[0043] Once connected to the line port external pressure can be applied to collapsible housing 22 by for example squeezing, pinching, or pushing inward on the housing to displace dispenser 26 thereby opening or displacing valve 28 from receiving port 30. Continued squeezing or external force can be utilized to dispel or eject 6

CA 02893151 2015-05-28

WO 2007/137056 PCI7US2007/069015 contents of chamber 23 through connector 24 and into the connected port. Depending upon the volume of chamber 23 the injected cleansing solution may extend into the intravascular line itself. After dispelling the contents of chamber 23 device component 12 can be removed from the port to allow administration of fluids to be delivered intravascularly (for example). If such delivery is not to be performed immediately upon cleansing, component 12 of the cleansing device can be retained on the port until such time as intravascular delivery is desired.

[0044] In another aspect, the above-described device and methodology can be utilized for administering an anti-clot agent to minimize or prevent intravascular associated clot formation or to dissolve an existing clot. In this aspect, rather than or in addition to the antimicrobial agent, chamber 23 can contain an appropriate anticoagulant agent or clot dissolving agent. Exemplary anti-clot agents which can be utilized include but are not limited to anticoagulants such as EDTA, sodium citrate, heparin and heparin derivatives, and anti-thrombolytic agents such as tissue plasminogen activator. Where lipid accumulation is an issue an appropriate dispersion or lipolytic agent can be administered, either independently or in combination with antimicrobial agent and/or anti-clot agent. Injection of any such agents can be achieved in a manner analogous to that described above relative to the cleansing agent. These applications may also be accomplished utilizing the embodiments Illustrated and described below.

[0045] An alternative embodiment of a device in accordance with the invention is illustrated and described with reference to Figs. 6-11. Referring to Fig. 6, such illustrates an alternative example port access device 40 having a syringe-like first component 42 and a second component 44. Referring to Fig. 7 syringe-like first component 42 includes a plunger 46. An exploded view of the port access device is depicted in Fig. 8. First component 42 includes a syringe barrel-like housing 48 having a first end 50 and a second end 52 with an internal chamber 54. Chamber 54 can preferably have a fluid volume of from 1 to about 3.5 ml. Housing 48 can have appropriate calibration marks as discussed above with respect to the eartier embodiment.

[0046] Plunger 46 can include a stem portion 56 having a seal 57. Plunger 46 can be insertable into second end 52 of housing 48. A second seal 59 can be associated with the larger diameter body of the plunger. Seal 59 is preferably present to form a seal between the plunger and an internal surface of the device chamber. Seal

CA 02893151 2015-05-28

WO 2007/137056 PCT/US2007/069015 can preferably be an elastameric seal which is over molded onto the piston (which can preferably be a molded hard plastic material). However, the invention contemplates alternative seal material and use of non-overmolded techniques.

[0047] Seal 57 can be a single seal or a set of seals and can be for example a set of two o-rings, a single broad overmolded elastameric o-ring or sleeve or a hard plastic seal molded integrally with the piston stem. The presence of seal 57 can advantageously inhibit or prevent unwanted or unintentional backflow of fluid into the device chamber thereby decreasing the risk of contamination of the device and/or its contents. Alternatively relative to the depicted configuration a single seal can be over molded to have a base portion which forms the seal between an internal wall of the device chamber and the large diameter portion of the piston and a sleeve portion which covers the walls of the smaller diameter portion of the piston (not shown).

[0048] The second component 44 is a removable cap portion having a housing and an internal container 62. Container 62 can contain an applicator material 64. The applicator material can be, for example, any of those materials discussed above with respect to the earlier embodiment. The second component 44 can additionally contain a cleansing agent such as those cleansing agents discussed above. Second component 44 preferably can be configured to fit over or onto an intravascular port such that the cleansing agent can be applieo Io external surfaces of the port. Such cleaning preferably can be conducted prior to administering the contents of chamber 54 (for example, an anti-clot, antimicrobial or other cleansing agent) into the port. However, the invention contemplates post-administration cleansing of the port utilizing the removable cap portion.

[0049] Referring next to Fig. 9, such shows a cross-sectional view of the embodied device 40 in an intact configuration. For utilization second component 44 can be removed and utilized to cleanse external surface of the port. Subsequently, first end 50 of the second component can be attached to the port and contents of the chamber 54 can be administered into the port by application of force to plunger 46. Alternatively, chamber 54 can be provided empty or can be provided to contain, for example, an anticoagulant agent and device 40 can be provided with plunger 46 in a forward position. Thus device 40 can be utilized for applications such as obtaining and/or testing of a blood sample from an individual by attaching first end 50 of the device to the port and repositioning of plunger 46 to draw fluid through the port into chamber 54.

CA 02893151 2015-05-28

WO 2007/137056 PCT/US2007/069015 [0050] Referring to Fig. 10 packaging 70 for delivery, storage and/or disposal of the component for access device 40 is illustrated. Such packaging includes a lid 72 and a tray portion 74. Tray portion 74 has a cavity 76 with molded retainers 78 for positioning/retaining of the device and assisting in maintaining the integrity of the device and proper positioning of the plunger relative to the device chamber. Such packaging can be sealed and can be utilized to provide a sterile environment for device 40. As shown in Fig. 11 a series 71 of individual packaging unit 70 can be provided with individually sealed units to allow individual removal of units while maintaining sterility of additional units in the series.

[0051] Another alternative embodiment is described with reference to Figs. 1213. In this embodiment first component 42a is the same as the immediately preceding embodiment. However, referring to Fig. 12 second component 44a comprises a “dual cap system. Cap housing 60a includes container portion 62 and a second cap extension 65 which houses a second container 66. Container 62 can contain an applicator material 64 such as the sponge-like materials described above. Similarly container 66 can also contain a sponge or other applicator material 67. Container 62 can further contain a cleansing agent such as those described above.

[0052] Container 66 can preferably contain one or more microbiocidal agents that differ in composition from the cleaning solution contained in the cleansing cap 62. An example agent composition within cap portion 65 can include from about 3% to about 11% H₂O₂. Additional components of the agent can include for example ethanol (from about 30% to about 40%) sodium citrate (from about 1% to about 4%), EDTA, and/or peracetic acid (less than or equal to about 11%). Preferably, the pH will be between 5 and 10 and can be adjusted with NaOH or other appropriate base/acid to about ph 7.4 as needed based upon the physiological pH and biocidal activity. The presence of EDTA can provide sporocidal activity against for example bacillus spores by complexing Mn and can additionally help stabilize H₂O₂. In combination with H2O2 in the solution a synergistic and/or additive effect can be achieved. The invention does contemplate use of alternative chelators and pH stabilizers relative to those indicated.

[0053] It is to be noted that in some instances a similar solution having lower peroxide content may be included within the first container 62 and in particular instances may be present within the chamber of the first component.

[0054] Referring to Fig. 13 such shows an intact device prior to use. In port cleansing applications second component 44a is removed from the device and portion 9

CA 02893151 2015-05-28

WO 2007/137056 PC17US2007/069015

60a is utilized to cover a port thereby contacting the port with the contents of container 62. Applicator material 64 can assist in applying the cleaning agent to external port surfaces. When the contents of chamber 54 are to be administered, component 44a is removed from the port and first component is attached to the port. Plunger 46 is depressed thereby injecting the contents of chamber 54 into the port. The syringe component is then removed from the port. A removable seal 68 can then be removed from second cap portion 65. Cap portion 65 can be placed over the port such that the contents of container 66 contact the port. Second component 44 can then be removed from the port or can be retained on the port until further port access or manipulation is desired.

[0055] Referring to Fig. 14 such shows an alternative embodiment wherein port access device 40b comprises a first component 42b, a second component 44b and a third component 45b where second component 44b and third component 45b are independently removable caps. As illustrated the caps are disposed initially at opposing ends of the device and are of differing size. However, alternative relative size and positioning of the caps on the device is contemplated. For example, first component 44b and second 45b can be disposed on top-side or bottom-side of wing extensions 51, 53 of chamber housing 48b.

[0056] For the example configuration illustrated, the larger cap (first component 44b) can be removed from the device and can be utilized for external port cleaning in a manner analogous to that described above. The second smaller cap (third component 45b) can be removed from the device after administration of the chamber contents and can be subsequently utilized as a port cap to protect the port until subsequent port access is desired as described above. Third component 45b optionally can contain an applicator material 82 and/or cleansing agent or microbiocidal agent as described above.

[0057] Alternative two-cap configurations include a device having a larger cap external to a smaller internal cap, the first cap being removable from the second cap where one of the first and second caps is configured for utilization as a port cap.

[0058] In the device shown in Fig. 14, cap housing 60b of second component 44b and cap housing 80 of third component 45b can be of differing colors. As such, the caps can be color coded (or otherwise coded) to notify the user or other personnel of the status of the port or intravascular line. For example, a first color such as green can be utilized on all or a portion of cap housing 80 which will be retained on the port after 10

CA 02893151 2015-05-28

WO 2007/137056 PCT/US2007/069015 use of the device to signify a properly sterilized port. Cap housing 60b can be a second color (e.g., yellow or red) signifying the cleansing or other procedure being performed has not yet been completed. Accordingly, the caps can be utilized as an added safety measure to help ensure proper use and assist in maintaining sterility and appropriate record keeping. For example, the caps can allow visual monitoring and can be tracked by hospital pharmacy and/or central auditing software.

[0059] In addition to visual auditing of compliance to proper cleaning and maintenance of sterility, a barcode, radio frequency identification (RFID) and/or other pharmacy dispensary or inventory control system associated with the device can be utilized to provide an independent audit/compllance system.

[0060] Referring next to Fig. 15 such depicts an additional alternate embodiment which can utilize a conventional type syringe and plunger design and can utilize caps in accordance with the invention. Accordingly, first component 42c comprises a syringe housing 48c and can have a LEUR-LOK® fitting at first end 50. Plunger 46c can have a conventional type piston seal 57c configured to insert into second end 52 of housing 48c and form a seal with the walls of chamber 54c. Second component 44c can comprise a housing 60c which can for example have an internal receiving port which fits either internally relative to the LEUR-LOK® fitting or which fits over and covers the LEUR-LOK® fitting at first end 50 of first component housing 48c. Third component 45c can also have housing 80c configured such that it comprises an internal receiving port which fits either internally relative to a LEUR-LOK® fitting or which fits over and covers the LEUR-LOK® fitting (or which can have an alternative type fitting) based upon the type of port being cleansed.

[0061] A cross-sectional view of the device shown in Fig. 15 is illustrated in Fig. 16. Such shows the exemplary type of cap housings for covering LEUR-LOK®-type fittings. For example third component 45c has housing 80c comprising a portion of such housing which fits internally within a LEUR-LOK® type fitting thereby capping such fitting. In contrast second component 44c has housing 60c which is threaded to thread onto LEUR-LOK® type fitting. It is to be understood that the depiction is for illustrative purposes only and that either or both caps can have the threaded configuration or the snap in configuration. Cap housing 60c and 80c can further be color coded as described above.

[0062] The invention also contemplates dual cap system disposed at the distal (non-administration) end of the port cleaner device (not shown). In this dual cap system 11

CA 02893151 2015-05-28

WO 2007/137056 PCTAJS2007/069015 a first “green cap can be reversibly joined to both lhe device and also back to front in a stack relationship relative to a second yellow cap. Each of the two caps can be, for example, a LEUR-LOK®type fitting cap, friction fit cap, etc. The green cap can contain the microbiocide composition described above. The yellow cap can contain for example the cleaning compositions discussed earlier or the microbiocide composition as contained in the green cap since in this configuration the yellow cap is not in contact with the administration end of the device.

[0063] Possible materials lor caps include, but are not limited to, polyethylene, polypropylene, and/or copolymer materials. Further, the caps can preferably comprise a material or agent that is UV protective to preserve the integrity of hydrogen peroxide during storage, shipping, etc. Packaging may also contain UV protective materials to inhibit peroxide breakdown.

[0064] As mentioned above, devices of the invention can be utilized for withdrawing blood from an individual through an intravascular catheter or intravascular port. In particular applications, the device can be utilized directly for blood testing purposes. The device chamber can preferably have a chamber size in the range of 1 to 3 ml, with appropriate calibration marks as discussed above. Where whole blood is desired, depending upon the particular purpose for drawing, blood can be drawn into either a device having an empty chamber or into a device containing an anticoagulant such as EDTA, sodium citrate or alternative coagulant (such as discussed above). The device containing blood and anticoagulant can then be utilized directly in blood testing equipment or blood can be transferred to an alternative device for testing.

[0065] In applications where serum is desired, whole blood can be drawn into the device chamber and, after coagulation, the device containing the blood sample can be spun to separate the serum from the red blood cells. If anticoagulant is present in the device chamber, further separation can occur to isolate plasma. Alternatively, a filter such as a MILLIPORE® (Millipore Corp., Bedford MA) filter can be fitted onto the device after a sample is drawn into the device chamber. Such technique can filter out red blood cells, white blood cells and platelets allowing serum to flow from the chamber white retaining the blood cells within the filter. Anticoagulants can optionally be provided within the chamber to allow transfer of blood cells or plasma if such is desired based upon the testing or other procedure to be performed (i.e., complete blood count, CBC, platelet count, reticulocyte count, T and B lymphocyte assays and chemistries).

WO 2007/137056 PCT7US2007/069015 (0066] An appropriate filter can also be utilized to filter out particulates during drawing of a blood sample from an individual into the chamber.

[0067] It is to be understood that any of the devices above can be utilized for cleansing purposes, for administration purposes or for blood drawing/testing purposes. Methodology will be analogous with variation based upon the particular device utilized as described above.

[0068] Example device packaging is illustrated in Figs. 17-19. Packaging 100 can include a lid portion 102 and a packaging tray 104 as shown in Fig. 17. Referring to Fig. 18 and 19 packaging tray 104 can be a molded tray which has integrally molded retaining features which conform to the shape of a device 40c in accordance with the invention. Preferably the molded features conform to the shape of the device in the non-deployed position for shipment, storage, etc. Accordingly tray 104 can have one or more integrally molded retainer features 106, 107, 108 and 109. Tray 104 can also comprise an integrally molded receiving stand 110 which can be configured to receive device 40c in an upright position as depicted in Fig. 18. Such receiving stand can allow device 40c to be inserted and retained during administrative procedures or after use. Tray 104 may also be used for device disposal purposes.

[0069] Device caps in accordance with the invention can be utilized independent of the devices for cleansing and protection of alternative access catheters and ports such as intravascular, peritoneal dialysis, urinary ports and catheters, etc. Accordingly, the caps can be packaged independently in pairs (one each of two differing sizes, colors, etc., in groups or in bulk, of one or more colors). Figs. 20-21 show an example two cap packaging system 115 having a first cap 117 which can be for example a yellow cap and which can preferably be a LEUR-LOK® type cap and a second cap 118 which can be, for example, a green cap and which can also be a LEUR-LOK®. Packaging system 115 can comprise a packaging tray 120 and as illustrated in Fig. 21 can include integrally molded appropriate receiving ports/receiving rings 122,124. Where additional or fewer caps are to be packaged together tray 120 can have an appropriate number of receiving ports for receiving and reversibly retaining the caps. Where the caps differ in size (diametric), the ports can also be of differing size as appropriate. It is to be understood that the caps may be provided in groups such as one green and four yellow caps per package or any other appropriate number depending upon the particular procedure for which they will be utilized with the number and size of package ports corresponding to the number and size of various caps.

WO 2007/137056 PCT/US2007/069015 [00701 Referring next to Fig. 22 an alternative packaging system 130 is illustrated. Packaging system 130 comprises a lid 132 and a tray 130 having integral receiving ports 136 and 138 for receiving caps 117 and 118. As discussed above alternative numbers and sizes of receiving ports can be provided based upon the number and sizes of caps to be utilized.

[0071] Where caps are provided in bulk, such may be individually packaged and may be provided individually in sheets or on strips. Caps can alternatively be provided with catheter or line/import devices. Such can be included in common packaging either loose or attached to a port catheter or line to be used for port cleaning and/or protection after package opening and/or while the device is in use. In some instances the cap(s) can be packaged in one or more sub-packages included within a larger package enclosing the catheter device.
