Biopsy device with integral vacuum assist and tissue sample and fluid capturing canister
First Claim
1. A biopsy device comprising:
- (a) a probe cannula defining an internal passage and having a side aperture;
(b) a cutter translatable relative to the probe cannula to sever a tissue sample received in the probe cannula;
(c) a vacuum source in communication with the cutter;
(d) a container, wherein the container includes a tissue sample holder located in the container, wherein the tissue sample holder is configured to capture solid tissue samples while allowing fluid to escape the tissue sample holder, wherein the tissue sample holder is configured to hold the solid tissue samples within the container; and
(e) a conduit, wherein the conduit is configured to provide fluid communication between the container and a proximal end of the cutter, wherein the conduit is further configured to communicate solid tissue samples from the cutter to the tissue sample holder, wherein at least a portion of the conduit includes a flexible tube coupling the container with the probe cannula such that the probe cannula is movable relative to the container, wherein the conduit is positioned above a horizontal plane defined by the tissue sample holder and terminates at an end within the container.

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.

15. A biopsy system comprising:
-
(a) a biopsy device including; (i) a body, (ii) a cannula defining an internal passage and having a side aperture, and (iii) a cutter translatable relative to the probe cannula to sever a tissue sample received in the probe cannula; (b) a sample collection assembly including; (i) a tissue sample holder extending entirely around an inner perimeter of a container such that the tissue sample holder is configured to separate solid tissue samples from fluid as vacuum is communicated through the container, wherein the tissue sample holder is further configured to hold tissue samples severed by the cutter; and (ii) a conduit extending from the tissue sample holder to the biopsy device;
wherein the conduit is configured to communicate tissue samples from the biopsy device to the tissue sample holder, wherein at least a portion of the conduit includes a flexible tube coupling the sample collection assembly with the cannula such that the cannula is movable relative to the sample collection assembly;
wherein at least a portion of the conduit includes an elbow portion, wherein the elbow portion is configured to direct tissue samples toward the tissue sample holder. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
