TISSUE CUTTING MEMBER FOR A BIOPSY DEVICE DESCRIPTION
FIELD OF THE INVENTION
The present invention relates generally to tissue cutting members for tissue removal devices such as biopsy devices and the like.
BACKGROUND OF THE INVENTION
In the diagnosis and treatment of certain medical conditions, such as potentially cancerous tumors, it is usually desirable to perform a biopsy, where a sample of the suspicious tissue is removed for examination and pathological analysis. In many cases, the suspicious tissue is located in a subcutaneous site, such as inside a human chest. To minimize surgical intrusion into the patient's body, it is desirable to be able to insert a small instrument into the patient's body to access and separate the biopsy sample from the designated site.
Tissue cutting members commonly used with biopsy devices have a variety of problems. Tissue is often trapped between the cutting member and the shaft within which the cutting member is disposed. Likewise, many cutting members commonly available in the art are not suitable for effectively separating difficult or hard tissue from the target site on a patient body.
ES 2 350 366 T3
-2 There is a need in the art for cutting members with improved efficiency for separating tissue samples from a target location on a patient body.
US 2004/167428 A1 describes a biopsy device with a tissue cutting member according to the preamble of claim 1. US-B1-6 258 111 describes a tissue cutting member for separating a tissue sample from a target within the body of a patient comprising a distal tubular portion having a distal tip with an outer tissue cutting edge, a tissue receiving opening and a longitudinal axis; a longitudinally oriented opening in the distal tubular portion having an open distal end leading into the internal tissue receiving opening and a closed proximal end and at least one second opening in a wall of the circumferentially spaced distal tubular portion of the longitudinally oriented opening around the longitudinal axis.
SUMMARY OF THE INVENTION
This invention is directed to tissue cutting members for devices for separating tissue from a target site within the body of the patient. More particularly, the invention is directed to tissue cutting members and biopsy devices that utilize tissue cutting members of this nature for the separation of a tissue sample from the supporting tissue at the target site within a patient. An appropriate biopsy device having a cannula that can be used with a cutting member of
ES 2 350 366 T3
-3 fabric having characteristics of the invention is described in US 2005/0159677 A1.
A tissue cutting device having a tissue cutting member in accordance with the present invention is defined by independent claim 1. Preferably the distal tip of the distal tubular portion has a beveled anterior face with a leading edge and a trailing edge.
The distal tubular portion preferably has a plurality of apertures circumferentially spaced from the open-ended slot about the longitudinal axis, and preferably the centers of these apertures are located circumferentially in the vicinity of 90 °, 135 °, or 180 ° from from a midpoint of the longitudinally oriented opening. The circumferentially spaced aperture (s) may be of a variety of shapes, for example a rectangular shape, a circular shape, or an elongated shape such as an oval or elongated slot. One or more of the openings in the distal tubular portion may be of one shape and one or more of the openings in the distal tubular portion may be of another shape. The openings allow the vacuum to be maintained within the biopsy device when the cutting member makes the cut and provide stress relief, facilitating radial expansion and / or contraction.
The distal tubular portion preferably has a flared distal section with a proximal end and a distal end, and a proximal configuration section.
ES 2 350 366 T3
-4 cylindrical with a proximal end and a distal end. The open distal end of the longitudinally oriented opening facilitates flare of the flared distal section. The flared distal section ensures that the outer tissue cutting edge of the distal tubular portion engages an inner tissue cutting edge of a tissue receiving opening in the cannula of the biopsy device to cleanly cut the tissue sample from the supporting tissue and provide a better tissue sample for pathological examination.
These and other advantages of the invention will become more apparent from the following detailed description of the invention and the accompanying exemplary drawings.

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 shows an embodiment of a probe component 10 that includes a housing 12 and an outer tubular member or cannula 14. The tissue cutting member 16 incorporating features of the invention is slidably disposed within an interior cavity 18 at the cannula 14. The probe component 10 may be part of a biopsy device such as that described in US 2005/0159677 A1. Details of the probe component 10 and other parts of the biopsy device can be found in the aforementioned patent.
The cannula 14 of the probe component 10 has a distal lip 20 and an open tissue receiving opening 22 spaced proximal to the distal tip 20. The tissue receiving opening 22 has an internal tissue cutting edge 24. The cutting member of Tissue 16 is slidably disposed within the internal cavity 18 of the cannula 14 of the probe component, as shown in Figure 2.
The distal tip 20 of the cannula 14 can have a variety of tip shapes. The shape of the tissue penetrating distal tip described in the aforementioned patent US 2005/0159677 A1 has been found suitable for penetrating tissue, particularly breast tissue. Alternatively, the distal tip 20 may have a
ES 2 350 366 T3
