Biopsy device with integral vacuum assist and tissue sample and fluid capturing canister
First Claim
1. A biopsy device comprising:
- (a) a body;
(b) a probe cannula defining an internal passage and having a side aperture, wherein the probe cannula is configured to extend distally from the body;
(c) a cutter translatable relative to the probe cannula to sever a tissue sample received in the probe cannula;
(d) a vacuum source in communication with the cutter;
(e) a tissue receiving assembly, wherein the tissue receiving assembly is remote relative to the body, wherein the tissue receiving assembly comprises;
(i) an outer container, and(ii) a removable portion selectively removable from the outer container,wherein the tissue receiving assembly is configured to separate solid tissue samples from fluid, wherein the removable portion is further configured to hold the solid tissue samples;
(f) a flexible tube coupling the tissue receiving assembly with the body such that the body is movable relative to the tissue receiving assembly; and
(g) a first conduit between the flexible tube and a proximal end of the cutter, wherein the first conduit is configured to communicate solid tissue samples to the tissue receiving assembly via the flexible tube.

Abstract
A biopsy device includes a body, a probe cannula, a cutter, a vacuum source, a tissue sample holder, and a flexible tube. The probe cannula extends distally from the body and defines an internal passage with a side aperture. The cutter is translatable relative to the probe cannula to sever a tissue sample received in the probe cannula. The vacuum source is in communication with the cutter. The tissue sample holder includes a vacuum port on the exterior surface to communicate with the vacuum source and a removable portion to hold solid tissue samples. The removable portion is selectively removable from the tissue sample holder and includes a straining member to separate fluids from solids. The flexible tube couples the tissue sample holder with the body such that the tissue sample holder is flexibly spaced away from the body.
