Abstract

A tissue biopsy and processing device for capturing and processing a tissue sample is provided. In general, the device includes a biopsy member adapted to remove a tissue sample from a patient'"'"'s body, and a processing apparatus adapted to receive the tissue sample from the biopsy device, and to dissociate and mince the tissue sample in preparation for further use. The processing apparatus can include a tissue reducing chamber in communication with and adapted to receive the tissue sample from the biopsy member, and a tissue processing element associated with the tissue reducing chamber that is effective to dissociate the tissue sample retained within the tissue reducing chamber.

Claims

1. A tissue biopsy and processing device, comprising:

a biopsy member adapted to remove a tissue sample from a patient; and

a processing apparatus adapted to receive the tissue sample from the biopsy device, and to dissociate and mince the tissue sample in preparation for further use.

2. The device of claim 1, wherein the processing apparatus comprises:

a tissue reducing chamber in communication with and adapted to receive the tissue sample from the biopsy member; and

a tissue processing element associated with the tissue reducing chamber that is effective to dissociate the tissue sample retained within the tissue reducing chamber.

3. The device of claim 2, wherein the device is in the form of an elongate member having a proximal end, a distal end, and an inner lumen extending therebetween, the biopsy member being formed on the distal end of the elongate member and the tissue reducing chamber being formed within the inner lumen proximal to the distal end of the elongate member.

4. The device of claim 3, wherein the biopsy member is effective to retrieve and convey a tissue sample to the tissue reducing chamber.

5. The device of claim 4, wherein the tissue processing element is disposed within the tissue reducing chamber.

6. The device of claim 5, wherein the tissue reducing chamber is formed integrally with the biopsy member.

7. The device of claim 1, wherein the biopsy member is selected from the group consisting a suction member, a cutting member, a burr, a shaver, a curette, a rongeur, a high pressure fluid jet, a grasping member, a needle, and combinations thereof.

8. The device of claim 2, wherein the tissue reducing chamber includes an isolation member effective to prevent foreign substances from entering the reducing chamber after a tissue sample is disposed within the chamber.

9. The device of claim 8, wherein the isolation member comprises a hinged flap movable between an open position, in which the chamber can receive a tissue sample, and a closed position, in which the chamber is sealed.

10. The device of claim 2, wherein the tissue processing element comprises a high pressure fluid jet.

11. The device of claim 10, further comprising a tissue retaining element for holding a tissue sample while the high pressure fluid jet applies a high pressure fluid to the tissue to process the tissue.

12. The device of claim 11, wherein the tissue retaining element comprises a filter having pores sufficient to retain the tissue while allowing the high pressure fluid to flow therethrough.

13. The device of claim 2, wherein the tissue processing element comprises a mechanical cutting element.

14. The device of claim 13, wherein the mechanical cutting element is selected from the group consisting of an auger, a rongeur, a curette, an awl, a reamer, a corer, a blade, a grinding member, a grating member, and combinations thereof.

15. The device of claim 2, further comprising a siphoning member in communication with the tissue reducing chamber that is effective to receive a tissue sample after the tissue sample is processed by the tissue processing element and to remove excess fluid from the tissue sample.

16. The device of claim 2, further comprising a bioimplantable tissue scaffold in communication with the tissue reducing chamber that is effective to receive a tissue sample after the tissue sample is processed by the tissue processing element.

17. The device of claim 2, further comprising a bioimplantable mesh in communication with the tissue reducing chamber that is effective to receive a tissue sample after the tissue sample is processed by the tissue processing element.

18. A method for preparing a tissue slurry, comprising:

providing a device having a biopsy member for retrieving a tissue sample from a patient, and a processing element in communication with the biopsy member that is effective to dissociate and mince the tissue sample;

removing a tissue sample from a patient'"'"'s body using the biopsy member; and

processing the tissue sample with the processing element to dissociate and mince the tissue.

19. The method of claim 18, further comprising collecting the dissociated and minced tissue for subsequent use.

20. The method of claim 19, wherein the dissociated and minced tissue is collected onto a tissue scaffold.

21. The method of claim 20, wherein the dissociated and minced tissue sample is disposed within a fluid, and wherein the tissue scaffold is fluid permeable to enable the fluid to flow therethrough, thereby separating the dissociated and minced tissue from the fluid.

22. The method of claim 18, wherein the particle size of the dissociated and minced tissue fragments is in the range of about 0.1 mm³ to 3 mm³.

23. The method of claim 18, wherein the particle size of the dissociated and minced tissue fragments is less than about 1 mm³.

24. The method of claim 18, wherein the dissociated and minced tissue is in the form of an amorphous slurry.
