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.

Claims15

Dependent claims

A method of joining tissue, comprising the steps of:

providing an apparatus including:
an anvil;
a body portion juxtaposed with respect to one another along a shaft and arranged so as to be approximated with respect to one another;
a support structure supported on the shaft;
and
a sleeve extending circumferentially around the shaft and configured to contain the support structure in a first collapsed condition therewithin;
deploying the support structure outwardly from the sleeve, from the first collapsed condition to a second expanded condition, such that the support structure extends radially from the shaft and is positioned between a first tissue section and a second tissue section, the support structure including a wound treatment material for joining tissue;
and
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.
