Abstract

According to an aspect of the present disclosure, an apparatus for forming an anastomosis between adjacent intestinal sections of tissue is provided. The apparatus includes an anastomosis device having an anvil and a tubular body portion, wherein the anvil is selectively attachable to the tubular body portion by a shaft; and a support structure for deposition between the intestinal sections of tissue. The support structure includes a body defining an aperture therein for receiving the shaft. The body has an outer terminal edge. The support structure includes at least one layer of expandable material disposed at the outer terminal edge of the body.

Claims

1. An apparatus for forming an anastomosis between adjacent intestinal sections of tissue, comprising:

a) a device having an anvil and a body portion, the anvil being selectively attachable to the body portion by a shaft, the shaft having channels for delivering fluid; and

b) a support structure including at least one layer of expandable material, the support structure having an unexpanded condition and an expanded condition, the support structure being disposed between the anvil and the body portion and the channels are arranged to deliver the fluid to the support structure, the support structure including a foam material, and wherein the foam is a wound treatment material.

2. The apparatus according to claim 1, wherein the support structure expands from the unexpanded condition to the expanded condition upon delivery of the fluid to the support structure.

3. The apparatus according to claim 1, wherein the fluid is a reactive substance.

4. The apparatus according to claim 1, wherein the support structure is disposed on the shaft.

5. The apparatus according to claim 1, wherein the support structure expands in thickness.

6. The apparatus according to claim 1, wherein the support structure expands radially.

7. An apparatus for forming an anastomosis between adjacent intestinal sections of tissue, comprising:

a) a device having an anvil and a body portion, the anvil being selectively attachable to the body portion by a shaft, the shaft having channels for delivering fluid; and

b) a support structure including at least one layer of expandable material, the support structure having an unexpanded condition and an expanded condition, the support structure being disposed between the anvil and the body portion and the channels are arranged to deliver the fluid to the support structure, wherein the support structure includes a bio-absorbable material.

8. The apparatus according to claim 7, wherein the support structure expands from the unexpanded condition to the expanded condition upon delivery of the fluid to the support structure.

9. The apparatus according to claim 7, wherein the fluid is a reactive substance.

10. The apparatus according to claim 7, wherein the support structure includes a foam material.

11. The apparatus according to claim 10, wherein the foam is wound treatment material.

12. The apparatus according to claim 7, wherein the fluid and the support structure form a wound treatment material.

13. The apparatus according to claim 7, wherein the support structure is disposed on the shaft.

14. The apparatus according to claim 7, wherein the support structure includes a mesh material.

15. The apparatus according to claim 7, wherein the support structure expands in thickness.

16. The apparatus according to claim 7, wherein the support structure expands radially.

17. The apparatus according to claim 7, wherein the support structure includes a material selected from the group consisting of a sealant and an adhesive.

18. An apparatus for forming an anastomosis between adjacent intestinal sections of tissue, comprising:

a) a device having an anvil and a body portion, the anvil being selectively attachable to the body portion by a shaft, the shaft having channels for delivering fluid; and

b) a support structure including at least one layer of expandable material, the support structure having an unexpanded condition and an expanded condition, the support structure being disposed between the anvil and the body portion and the channels are arranged to deliver the fluid to the support structure, wherein the support structure includes a material selected from the group consisting of a sealant and an adhesive.

19. The apparatus according to claim 18, wherein the support structure expands from the unexpanded condition to the expanded condition upon delivery of the fluid to the support structure.

20. The apparatus according to claim 18, wherein the fluid is a reactive substance.

21. The apparatus according to claim 18, wherein the fluid and the support structure form a wound treatment material.

22. The apparatus according to claim 18, wherein the support structure is disposed on the shaft.

23. The apparatus according to claim 18, wherein the support structure expands in thickness.

24. The apparatus according to claim 18, wherein the support structure expands radially.
