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.

1. An apparatus for forming an anastomosis between adjacent intestinal sections of tissue, comprising: a surgical stapling instrument having a staple cartridge, an anvil, and a shaft, the anvil defining an outer terminal edge; anda support structure for deposition between intestinal sections of tissue, the support structure including: a body defining an aperture therein for receiving the shaft and having an outer terminal edge; andan outer portion comprising a pair of drapes, skirts, or membranes extending from the outer terminal edge of the body and radially beyond the outer terminal edge of the anvil, each drape skirt, or membrane of the pair of drapes, skirts, or membranes extending completely around the outer terminal edge of the body and having a first, undeployed condition and a second, deployed condition extending from the body. 2. The apparatus according to claim 1, wherein the surgical stapling apparatus comprises a body portion, wherein the anvil is circular in shape and movable toward and away from the staple cartridge. 3. The apparatus according to claim 1, wherein the support structure comprises a bio-absorbable material. 4. The apparatus according to claim 1, wherein the support structure comprises a mesh material. 5. The apparatus according to claim 1, wherein the outer portion of the support structure is fabricated from a polymeric film. 6. The apparatus according to claim 1, wherein in the first, undeployed condition the outer portion is rolled-up towards the body of the support structure. 7. The apparatus according to claim 1, wherein in the second, deployed condition the outer portion is unrolled to extend in a substantially parallel orientation with respect to a central axis defined by the shaft. 8. The apparatus according to claim 7, wherein the pair of drapes, skirts, or membranes of the outer portion includes a first membrane that is unrolled in a first direction and a second membrane that is unrolled in a second direction, opposite the first direction when in the second, deployed condition. 9. An apparatus for forming an anastomosis between adjacent intestinal sections of tissue, comprising: a stapling instrument having a staple cartridge, an anvil, and a shaft;a support structure for deposition between intestinal sections of tissue, the support structure including: a body defining an aperture therein for receiving the shaft; andan outer terminal portion including first and second membranes extending laterally from the body beyond an outer edge of the anvil, the first and second membranes overlapping one another and having a deployed condition lying generally along one of the intestinal sections of tissue. 10. The apparatus according to claim 9, wherein the first and second membranes are rolled-up towards the body of the support structure to define an undeployed condition. 11. The apparatus according to claim 10, wherein the support structure includes at least one tether securing the outer terminal portion in the undeployed condition. 12. The apparatus according to claim 11, wherein the at least one tether includes a free end extending from the outer terminal portion. 13. The apparatus according to claim 9, wherein the outer terminal portion includes an adhesive material so that in the deployed condition the outer terminal portion will adhere to a surface of at least one of the intestinal sections. 14. The apparatus according to claim 9, wherein each of the first membrane and the second membrane includes two layers.
