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.

Claims

1. An assembly for joining tissue, comprising:

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;

the body portion carrying a plurality of surgical staples in an annular configuration, the surgical staples being deployable against the anvil;

a support structure connected to the shaft, the support structure defining a cavity for containing a wound treatment material therein;

the shaft including at least one port in communication with the cavity for delivering the wound treatment material; and

,

an annular knife disposed radially inwardly of the surgical staples.

2. The assembly according to claim 1, wherein the support structure is bio-absorbable.

3. The assembly according to claim 1, wherein the support structure includes an inflatable annular tube.

4. The assembly according to claim 1, wherein the support structure is deployable from a first collapsed condition to a second expanded condition.

5. The assembly according to claim 1, wherein wound treatment material expands the support structure from a first collapsed condition to a second expanded condition.

6. The assembly according to claim 3, wherein an interior space of the annular tube defines a first chamber for receiving a first part of a two-part wound treatment material.

7. The assembly according to claim 6, wherein the interior space of the annular tube defines a second chamber for receiving a second part of the two-part wound treatment material.

8. The assembly according to claim 6, wherein the plurality of surgical staples have a second part of the two-part wound treatment material.
