摘要： A method for delivering a plurality of individual surgical fasteners includes the steps of providing a surgical fastener delivery device. The delivery device has a drive mechanism having a distal and a proximal end, and a first and a second opposing member. The members are moveable proximally and distally with respect to the delivery device, and individually with respect to each other. The delivery device further includes a plurality of surgical fasteners located between the first and the second members. Next, the surgical fastener delivery device penetrates tissue by moving the drive mechanism distally. A distal end of one of the fasteners is partially deployed by moving the first member proximally. Finally, the distal end of the fastener is fully deployed by moving the second member proximally.

摘要： A biopsy device comprises a probe and a holster. The probe has a distally extending needle and a central thumbwheel coupled with the needle. The needle has a transverse tissue receiving aperture. A cutter is translatable relative to the needle to sever tissue protruding through the aperture. The central thumbwheel is manually operable to rotate the needle to reorient the angular position of the aperture about the longitudinal axis defined by the needle. The central thumbwheel is positioned coaxially with the longitudinal axis. An elongate sleeve unitarily couples the needle with the central thumbwheel. A cable driven mechanism in the holster drives the cutter. A rotatable tissue sample holder is coupled with the probe, and has chambers configured to receive tissue samples communicated proximally through a lumen defined by the cutter. A piezoelectric motor in the holster drives the tissue sample holder.

摘要： A biopsy device targeting set includes a vertical member, a carriage that is vertically movable along the vertical member, and a cradle coupled with the carriage. The cradle has a pair of substantially perpendicular mounting arms. Each mounting arm has a recess that may receive a rail of the carriage, such that the cradle may be mounted to the same rail in different orientations. Each mounting arm also has a biopsy device mounting feature, which may be a recess or a rail. The biopsy device mounting feature is configured to engage with a complementary feature of a biopsy device, such that a biopsy device may be mounted to either mounting arm. A z-stop feature is operable to selectively restrict longitudinal motion along either or both of the biopsy device mounting features. The targeting set may be used with a biopsy device in an MRI environment.

摘要： A biopsy device includes a body portion, a tip, at least one blade, and a cutter. The cannula defines at least one lumen. The cannula has a transverse aperture configured to receive tissue. The tip is located at the distal end of the cannula, and may include at least two concave surfaces. The blade extends longitudinally from the tip. A second blade may also extend longitudinally from the tip. Blades may be axially staggered relative to the cannula. Blades may also have lengths that differ from one another. In addition, a blade may have a pointed distal end, or may have a curved distal edge. The configuration of the blade and tip may provide reduced force to penetrate tissue. The blade and tip may produce a cut length that is greater than or equal to the length of the outer perimeter of the cannula.
