Abstract

An apparatus for forming an anastomosis between adjacent intestinal sections of tissue is provided. The apparatus includes a circular surgical stapler having an anvil assembly with an anvil shaft and an anvil, the circular surgical stapler further having a tubular body portion with an annular knife and a body portion shaft selectively attachable to the anvil shaft; and a seal structure for deposition between the intestinal sections of tissue including a hub configured to engage attachment structure on at least one of the anvil shaft and the body portion shaft. The attachment structure is positioned so that the seal structure is located between the intestinal sections of tissue when the circular surgical stapler is disposed within the intestinal sections of tissue.

Claims

1. (canceled)

12. An annular surgical stapling device, comprising an anvil assembly and a tubular body portion, the anvil assembly having an anvil member and a first shaft, the tubular body portion carrying a plurality of surgical staples in an annular configuration, the tubular body portion having a second shaft disposed radially inward of the surgical staples, the first shaft of the anvil member being attachable to the second shaft of the tubular body, and the structure according to claim 1, the first shaft being received in the aperture of the at least one disc.

13. The annular surgical stapling device of claim 12, wherein the support structure is deployable from a first collapsed position on the first shaft to a second expanded position on the first shaft.

2. A support structure for deposition between intestinal sections, comprising at least one disc having a generally centrally located aperture, the support structure comprising a material selected from the group consisting of at least one of an adhesive, a sealant, a hemostat, and a medicament, and including at least one portion of a hook and a loop type fastener.

3. The structure of claim 2, wherein the support structure is impregnated with the material.

4. The structure of claim 2, wherein the support structure comprises an inflatable annular structure.

5. The structure of claim 2, further comprising a plurality of spokes extending radially inwardly from the disc.

6. The structure of claim 2, wherein an interior space of the support structure contains the material.

7. The structure of claim 2, wherein the support structure comprises a first layer and a second layer.

8. The assembly of claim 7, wherein the first layer comprises a first part of a two-part adhesive and the second layer comprises a second part of the two-part adhesive.

9. The structure of claim 7, wherein the first layer has a plurality of loops and the second layer has a plurality of hooks.

10. The structure of claim 7, wherein at least one of the first layer and the second layer are fabricated from a bio-absorbable material.

11. The structure of claim 2, wherein the at least one portion of a hook and loop fastener is fabricated from a bio-absorbable material.
