1. An apparatus for forming an anastomosis between adjacent intestinal sections of tissue, comprising:
- a) an anastomosis device having an anvil and a tubular body portion, the anvil being selectively attachable to the tubular body portion by a shaft; and
b) a support structure for deposition between the intestinal sections of tissue, the support structure including a body defining an aperture therein for receiving the shaft, the body having an outer terminal edge, the support structure including at least one layer of expandable material disposed at least at the outer terminal edge of the body and configured to expand while in a patient'"'"'s body, wherein the expandable material of the support structure has an un-expanded condition with an un-expanded dimension and an expanded condition with an expanded dimension greater than the un-expanded dimension,wherein the at least one layer of expandable material comprises a first and a second membrane extending from the outer terminal edge of the body portion, the first membrane expands in a substantially distal direction, and the second membrane expands in a substantially proximal direction.

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.
