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
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.
What is claimed is: 1. 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;
What is claimed is: 1. 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. 2. The method according to claim 1, wherein the support structure is bio-absorbable. 3. The method according to claim 1, wherein the support structure is a mesh-like material. 4. The method according to claim 1, wherein the step of deploying a support structure includes deploying the support structure from a first collapsed condition that is out of registration with the first and second tissue sections to a second expanded condition that is in registration with the first and second tissue sections, prior to the step of approximating. 5. The method according to claim 4, wherein the support structure includes a resilient material operatively associated therewith, wherein the resilient material expands the support structure from the first collapsed condition to the second expanded condition, thereby deploying the support structure. 6. The method according to claim 4, wherein the support structure includes an inflatable tube, the tube being deployable from the first collapsed condition to the second expanded condition. 7. The method according to claim 6, wherein the tube defines an interior space for receiving the wound treatment material therein in order to expand the support structure. 8. The method according to claim 7, wherein the interior space of the tube defines a first chamber for receiving a first part of a two-part wound treatment material. 9. The method according to claim 8, wherein the interior space of the tube defines a second chamber for receiving a second part of the two-part wound treatment material. 10. The method according to claim 8, wherein the body portion of the apparatus has a plurality of staples for being deployed against the anvil, the plurality of staples having a coating of a second part of the two-part wound treatment material. 11. The method according to claim 1, wherein the support structure includes a first layer and a second layer. 12. The method according to claim 11, wherein the first layer of the support structure comprises a first part of a two-part wound treatment material, and the second layer of the support structure comprises a second part of the two-part wound treatment material. 13. The method according to claim 11, wherein the support structure comprises a first part of a two-part wound treatment material, and further comprising the step of applying a second part of the two-part wound treatment material to the support structure. 14. The method according to claim 1, wherein the wound treatment material comprises an adhesive material. 15. The method according to claim 7, further comprising the step of puncturing the tube.
