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.

f) deploying the staples from the body portion; and

g) cutting the first tissue section and the second tissue section with the knife.

16. The method of claim 15, wherein:

a) the anvil assembly has a first shaft and the body portion has a second shaft, the first shaft being attachable to the second shaft; and

b) further including the step of attaching the first shaft to the second shaft before the step of approximating.

17. The method of claim 16, wherein:

a) the support structure has an annular shape and comprises a generally centrally located aperture; and

b) further including the step of inserting one of the first shaft and the second shaft into the aperture before the step of attaching the first shaft to the second shaft.

18. The method of claim 16, wherein the support structure is disposed on one of the first shaft and the second shaft before the step of approximating.
