Annular adhesive structure
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; 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.

15. A method of disposing a structure between tissue sections, the method comprising the steps of:
-
a) providing a surgical stapling device having an anvil assembly and a body portion, the anvil assembly having an anvil member and the body portion carrying a plurality of surgical staples and a knife;
b) inserting the anvil assembly into a first tissue section;
c) inserting the body portion in a second tissue section;
d) disposing a support structure between the first tissue section and the second tissue section, the annular structure comprising a wound treatment material;
e) approximating the anvil assembly and body portion with one another so that an end portion of the first tissue section, an end portion of the second tissue section and the support structure are disposed between the anvil member and the body portion, the support structure being disposed between the first tissue section and the second tissue section;
f) deploying the staples from the body portion; and
g) cutting the first tissue section and the second tissue section with the knife. - View Dependent Claims (16, 17, 18, 19)

31. A method of joining tissue, comprising the steps of:
-
providing an apparatus having;
an anvil; and
a body portion juxtaposed with respect to one another along a shaft and arranged so as to be approximated with respect to one another;
deploying a support structure from the shaft so as to dispose the support structure between a first tissue section and a second tissue section, the support structure including a wound treatment material for joining tissue;
approximating the anvil and body portion with one another so that the support structure is interposed between the first tissue section and the second tissue section. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
