Support structures and methods of using the same
First Claim
1. A method of disposing a support structure between adjacent intestinal sections, comprising the steps of:
- providing a circular surgical anastomosis device, the circular surgical anastomosis device including;
an anvil assembly having an anvil member and a first shaft; and
a tubular body portion having an annular knife operatively disposed therein and a second shaft disposed radially inward of the annular knife, the first shaft of the anvil assembly being selectively attachable to the second shaft of the tubular body;
inserting the anvil assembly into a first intestinal section;
inserting the tubular body portion into a second intestinal section;
disposing a support structure between the first intestinal section and the second intestinal section, the support structure having a body having an outer terminal edge and at least one layer of expandable material extending radially outward from the outer terminal edge;
approximating the anvil assembly and tubular body portion with one another so that an end portion of the first intestinal section, the support structure, and an end portion of the second intestinal section are disposed between the anvil member and the tubular body portion, the support structure being disposed between the first intestinal section and the second intestinal section;
firing the surgical anastomosis device to sever the portions of the first and second intestinal sections disposed radially inward of the annular knife, and to touch the portions of the first and second intestinal sections radially outward of the annular knife against the structure; and
expanding the at least one layer of expandable material.

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.

9. A method of performing a surgical anastomosis procedure, comprising the steps of:
-
providing an anastomosis apparatus having an anvil assembly movably mounted with respect to a tubular body portion; providing a support structure including a body having an outer terminal edge, and an aperture therethrough, the body being compressible; disposing an anvil assembly into a first intestinal section; disposing a distal end portion of the surgical stapling apparatus in a second intestinal section; positioning the support structure on a shaft of the anvil assembly; approximating the anvil assembly and the tubular body portion to capture the body of the support structure between the first intestinal section and the second intestinal section and to compress the body portion therebetween so that a portion of the body extends radially beyond the anvil member and the tubular body portion, at a location between the first and second intestinal sections, and remains substantially uncompressed thereby sealing a radial gap between the first intestinal section and the second intestinal section of the anastomosis site; and firing the anastomosis apparatus to join the first intestinal section, support structure, and second intestinal section. - View Dependent Claims (10, 11, 12)
