Abstract
A biopsy device may be used to obtain and store multiple tissue samples. The device permits the tissue samples to be stored in a sequenced fashion within a generally transparent tissue storage chamber disposed at a proximal end of the biopsy device. The tissue samples can be stored on flexible tissue sample strips arranged around the circumference of a rotating vacuum manifold disposed within the chamber.
Claims18
A biopsy device comprising:
- (a) a cannula extending distally from the biopsy device;
- (b) a tubular cutter translatable with respect to the cannula, the tubular cutter having a proximal end and a distal end, the cutter distal end for severing tissue received in the cannula;
- and
- (c) a tissue storage assembly disposed proximal of tubular cutter, the tissue storage assembly for receiving tissue samples severed by the tubular cutter, the tissue storage assembly comprising:
- (i) a generally transparent cover detachably coupled to a proximal end of the biopsy device,
- (ii) a rotatable member disposed at least partially within the generally transparent cover and detachably coupled to the proximal end of the biopsy device, the rotatable member having a plurality of longitudinal compartments extending proximally along the rotatable member, and
- (iii) at least one tissue holder carried by the plurality of longitudinal compartments, wherein the tissue holder is adapted to receive a plurality of tissue samples, and wherein the tissue holder is removable while the rotatable member is disposed within the generally transparent cover.
A tissue sample storage assembly for use with a biopsy device, the tissue sample storage assembly comprising:
- (a) a removable cover coupled to the biopsy device;
- (b) a rotatable manifold coupled to the biopsy device and disposed at least partially within the cover, the manifold having at least one vacuum passageway and a plurality of circumferentially spaced radial fins;
- and
- (c) at least one tissue sample strip disposed on an outer surface of the manifold and extending about at least a portion of the outer surface of the manifold, wherein the tissue sample strip is shaped to provide a plurality of tissue sample recesses disposed between adjacent radial fins of the rotatable member.
A biopsy device comprising:
- (a) a cannula;
- (b) a tubular cutter translatable with respect to the cannula, the tubular cutter having a proximal end and a distal end, wherein the cutter distal end is configured to sever tissue receiving in the cannula;
- and
- (c) a tissue storage assembly disposed proximal of the tubular cutter, wherein the tissue storage assembly is configured to receive tissue samples severed by the tubular cutter, the tissue storage assembly comprising:
- (i) a rotatable member defining a longitudinal axis of rotation, and
- (ii) at least two tissue holder releasably carried by the rotatable member, wherein the at least two tissue holder are configured to receive a plurality of tissue samples in a circumferentially spaced apart relationship relative to the axis of rotation, wherein each tissue holder includes a plurality of vacuum passageways sized to prevent passage of a tissue samples, and wherein each tissue holder is deformable from a generally arcuate configuration when carried by the rotatable member to a generally flatter configuration when the tissue holder is separated from the rotatable member.
