Abstract
A biopsy device includes a probe and holster that may be coupled together. The probe includes a cannula with a transverse opening and a cutter within the cannula. The holster includes a mechanism that is operable to rotate and translate the cutter within the cannula. In one example, the holster also includes a user interface having buttons and indicators. The indicators may indicate, e.g., the longitudinal position of the cutter within the cannula and an error condition. The buttons may be operable to, e.g., selectively and incrementally adjust the longitudinal position of the cutter within the cannula, initiate a sampling cycle, initiate a clear probe cycle, and initiate a lateral vacuum cycle. The user interface may also include a trigger operable to cock and fire the cannula into tissue. The user interface may be provided as one or more membranes on one or more sidewalls of the holster.

2. A biopsy device, wherein the biopsy device comprises:
-
(a) a cannula, wherein the cannula comprises; (i) a tissue piercing tip, and (ii) a transverse opening formed proximal to the tip; (b) a cutter translatable relative to the cannula, wherein the cutter is configured to sever tissue protruding through the transverse opening, wherein the cutter defines a cutter lumen; (c) a cutter actuation mechanism operable to translate the cutter relative to the cannula; and (d) a user interface in communication with the cutter actuation mechanism, wherein the user interface comprises; (i) a user input feature operable to initiate a sampling cycle, wherein the sampling cycle includes drawing a vacuum through the cutter lumen and translating the cutter, and (ii) one or more user input features operable to selectively and incrementally adjust the longitudinal position of the cutter to an incremental cutter position selected from a plurality of incrementally available cutter positions within the cannula, wherein the plurality of incrementally available cutter positions includes a proximal cutter position, a distal cutter position, and at least one intermediate cutter position between the proximal position and the distal position. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A biopsy device, wherein the biopsy device comprises:
-
(a) a cannula, wherein the cannula comprises; (i) a tissue piercing tip, and (ii) a transverse opening formed proximal to the tip; (b) a cutter translatable relative to the cannula, wherein the cutter is configured to sever tissue protruding through the transverse opening, wherein the cutter defines a cutter lumen; (c) a cutter actuation mechanism operable to translate the cutter relative to the cannula; (d) a holster having a pair of side panels; and (e) a user interface in communication with the cutter actuation mechanism, wherein the user interface comprises at least one membrane secured to at least one of the side panels of the holster, and wherein the user interface comprises; (i) a user input feature operable to initiate a sampling cycle, wherein the sampling cycle includes drawing a vacuum through the cutter lumen and translating the cutter, and (ii) a user input feature operable to initiate a clear probe cycle, wherein the clear probe cycle includes drawing a vacuum through the cutter lumen and reciprocating the cutter relative to the cannula.

21. A biopsy device, wherein the biopsy device comprises:
-
(a) a cannula, wherein the cannula comprises; (i) a tissue piercing tip, and (ii) a transverse opening formed proximal to the tip; (b) a cutter translatable relative to the cannula, wherein the cutter is configured to sever tissue protruding through the transverse opening, wherein the cutter defines a cutter lumen, wherein the cannula defines a lateral lumen external to the cutter, wherein the lateral lumen is parallel with the cutter lumen; (c) a cutter actuation mechanism operable to translate the cutter relative to the cannula; (d) a probe body, wherein the cannula extends distally from the probe body, wherein the cannula is translatable relative to the probe body, and wherein at least a portion of the cutter is positioned within the probe body; (e) a cannula firing mechanism operable to fire the cannula distally relative to the probe body; and (f) a user interface in communication with the cutter actuation mechanism and in communication with the cannula firing mechanism, wherein the user interface comprises; (i) a user input feature operable to initiate a sampling cycle, wherein the sampling cycle includes drawing a vacuum through the cutter lumen and translating the cutter, (ii) a user input feature operable to initiate a lateral vacuum cycle, wherein the lateral vacuum cycle includes drawing a vacuum through the lateral lumen, and (iii) a user input feature operable to cause the cannula firing mechanism to fire the cannula distally relative to the probe body.
