First Claim
1. A device for use in a biopsy procedure, wherein the device comprises:
- a. a body portion;
b. a needle, wherein the needle extends distally from the body portion, wherein the needle includes;
i. an outer cannula defining an inner lumen,ii. a tip, andiii. a lateral aperture configured to receive tissue, wherein the lateral aperture is proximal to the tip;
c. a cutter, wherein the cutter is operably configured to translate relative to the needle to sever a tissue specimen from tissue received within the lateral aperture; and
d. a tissue sample holder, wherein the tissue sample holder is configured to receive tissue specimens severed by the cutter, wherein the tissue sample holder includes;
i. an outer cup, wherein the outer cup defines an interior space, wherein the outer cup has a distal end and a proximal end, wherein the outer cup further includes a vacuum port located at the distal end, wherein the vacuum port is configured to couple with a vacuum source,ii. a cap, wherein the cap is selectively coupled with the proximal end of the outer cup, wherein the cap has at least one ejection feature, wherein the at least one ejection feature extends proximally from the cap when the tray is disposed in the outer cup, wherein a proximal end of the cap is closed by the at least one ejection feature, andiii. a tray, wherein the tray is configured to hold the severed tissue specimens, wherein the tray is selectively coupled with the cap by an interior receiving member of the cap, wherein the tray includes a pair of resilient latches and a post disposed between the resilient latches, wherein the interior receiving member of the cap is configured to grip the resilient latches, wherein the tray is configured to be ejected distally from the cap when the post of the tray is acted upon by the at least one ejection feature of the cap to thereby release the pair of resilient latches from the grip of the interior receiving member.

Abstract
A biopsy device comprises a body, a needle, a cutter, and a tissue sample holder. The tissue sample holder comprises an outer cup and a cap. A tray retains severed tissue samples from a biopsy procedure. In some versions, the tray is selectively detachable from the cap in a one-handed operation by the user. The tray may be ejected into a sample container, such as a formalin cup. The cap may include a threaded portion that is configured to engage a complementary threaded portion of a sample container to seal the sample container once the tissue samples have been transferred to the sample container from the tissue sample holder of the biopsy device. One or more ports may be provided in the cap to manage excess fluid within the outer cup of the tissue sample holder, and/or to provide integrated access for a marker delivery device.

16. A method of operating a biopsy device, wherein the biopsy device includes a cannula, a cutter, and a tissue sample holder, wherein the cannula includes a transverse tissue receiving aperture, wherein the cutter is configured to sever samples from tissue received through the transverse tissue receiving aperture, wherein the tissue sample holder is configured to receive one or more tissue samples severed by the cutter, wherein the tissue sample holder includes a chamber, a tray disposed in the chamber, wherein the tray has a pair of resilient latches and a cross member extending between the resilient latches, and a cap releasably engageable with the tray, wherein the cap includes a flexible portion, wherein the flexible portion defines an inner region, the method comprising:
-
(a) actuating the cutter to sever at least one tissue sample; (b) communicating the at least one tissue sample to the tray of the tissue sample holder, wherein the proximal end of the tissue sample holder is closed by the cap during the act of communicating the at least one tissue sample to the tray; (c) removing the cap, the tray, and the at least one tissue sample together from the chamber; and (d) releasing the tray from the cap by pressing distally on the flexible portion of the cap to thereby force the tray distally away from the cap, wherein the act of pressing distally on the flexible portion deforms the cross member of the tray to disengage the resilient latches of the tray from the inner region of the flexible portion. - View Dependent Claims (17, 18)
