Abstract

A biopsy system includes a cannula, a cutter, and a tissue sample holder. The cannula includes a closed distal end and a lateral tissue receiving port. The cutter is coaxially disposed with the cannula for severing tissue received in the tissue receiving port. The tissue sample holder includes a plurality of discrete tissue sample compartments. The biopsy system transports individual tissue samples to the discrete tissue sample compartments of the tissue sample holder.

Claims

1. A biopsy system comprising:

a cannula comprising a closed distal end and a lateral tissue receiving port;

a cutter coaxially disposed with the cannula for severing tissue received in the tissue receiving port; and

a tissue sample holder comprising a plurality of discrete tissue sample compartments;

wherein the biopsy system is operable to transport individual tissue samples to the discrete tissue sample compartments of the tissue sample holder.

2. The biopsy system of claim 1 wherein the tissue sample holder comprises a cassette.

3. The biopsy system of claim 1 wherein the tissue sample holder is portable.

4. The biopsy system of claim 1 wherein the tissue sample holder is rotatable.

5. The biopsy system of claim 1 wherein the tissue sample holder is positionable at a plurality of positions such that each tissue sample compartment may be sequentially aligned with respect to a discharge port of the biopsy system.

6. The biopsy system of claim 1 wherein the cannula is rotatable to position the tissue receiving port at a plurality of o'"'"'clock positions within a tissue mass being sampled, and wherein the tissue sample holder is positionable at a plurality of positions to correlate a tissue sample compartment with an o'"'"'clock position of the tissue receiving port.

7. The biopsy system of claim 1 wherein the cannula is rotatable, and wherein the biopsy system is operable to convey each severed tissue sample to a discrete tissue sample compartment in the tissue sample holder.

8. The biopsy system of claim 1 further comprising a vacuum source.

9. The biopsy system of claim 8 further comprising a control unit.

10. The biopsy system of claim 9 wherein the control unit is operable to correlate individual tissue samples with discrete locations.

11. The biopsy system of claim 9 wherein the control unit is operable to rotate the cannula to position the tissue receiving port at a desired o'"'"'clock position within tissue.

12. The biopsy system of claim 1 wherein the biopsy system is operable to transport severed tissue samples through a hollow tubular member to the tissue sample holder.

13. The biopsy system of claim 1 wherein the cannula is rotatable to adjust the angular orientation of the tissue receiving port within tissue.

14. The biopsy system of claim 1 wherein the tissue sample holder is positionable to correlate a tissue sample compartment with an angular orientation of the tissue receiving port.

15. The biopsy system of claim 1 wherein the biopsy system is operable to provide vacuum within the cannula adjacent the tissue receiving port.

16. The biopsy system of claim 1 wherein the biopsy system is operable to provide vacuum within the cutter.

17. The biopsy system of claim 1 wherein the biopsy system is operable to acquire multiple tissue samples around an axis of the cannula with a single insertion of the cannula into tissue.

18. The biopsy system of claim 1 further comprising a vacuum manifold adjacent the tissue receiving port.

19. The biopsy system of claim 1 further comprising a vacuum source, and wherein the biopsy system is operable to suction severed tissue samples into the tissue sample holder.

20. The biopsy system of claim 1 wherein the biopsy system is operable to suction severed tissue samples through a hollow interior of a tubular member.

21. A biopsy system comprising:

a cannula comprising a closed distal end and a lateral tissue receiving port;

a cutter coaxially disposed with the cannula for severing tissue received in the tissue receiving port; and

a tissue sample holder comprising a plurality of discrete tissue sample compartments;

wherein the biopsy system is operable to suction individual tissue samples to the discrete tissue sample compartments of the tissue sample holder.

22. A biopsy system comprising:

a biopsy instrument comprising;

a cannula having a closed distal end, at least one lumen, and a lateral tissue receiving port, and

a cutter a cutter coaxially disposed with the cannula for severing tissue received in the tissue receiving port;

a vacuum source;

a tissue sample holder comprising a plurality of discrete tissue sample compartments;

wherein the biopsy system is operable to advance the cutter to close the lateral tissue receiving port of the cannula;

wherein the biopsy system is operable to transport tissue samples from the cannula to the tissue sample holder; and

wherein the biopsy system is operable to provide fluid flow through the cutter.

23. The biopsy system of claim 22 wherein the biopsy system is operable to provide vacuum through the cutter.

24. The biopsy system of claim 22 wherein the biopsy system is operable to provide liquid flow through the cutter.

25. The biopsy system of claim 22 wherein the biopsy instrument comprises a fluid passageway distal of the lateral tissue receiving port for providing fluid flow through the cutter.

26. The biopsy system of claim 22 wherein the tissue sample is supported on the biopsy instrument.

27. The biopsy system of claim 22 wherein the tissue sample holder is rotatable.

28. The biopsy system of claim 22 wherein the tissue sample holder is portable.

29. The biopsy system of claim 22 wherein the biopsy system is operable to sequentially index the discrete tissue sample compartments.

30. The biopsy system of claim 22 wherein the tissue sample holder is movable with respect to a portion of the biopsy instrument such that each tissue sample compartment may be sequentially positioned to receive a tissue sample.
