First Claim
1. An assembly for disposing a support structure between intestinal sections, comprising:
- a) an annular surgical stapling device, having 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;
b) a support structure having a generally centrally located aperture for being disposed on one of the first shaft and the second shaft, wherein the support structure is deployable from a first collapsed position on the shaft to a second expanded position on the shaft; and
c) 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.

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.
