16. An assembly for disposing a seal element between tissue lumens comprising:
-
a circular surgical stapling device comprising an anvil assembly and a tubular body portion wherein the anvil assembly comprises an anvil member and a first shaft and the tubular body portion comprises a plurality of surgical staples in a circular configuration and a second shaft disposed inwardly of the surgical staples, the first shaft being attachable to the second shaft; and
a seal element comprising a first material and a second material wherein the first material promotes tissue ingrowth and the second material comprises a sealant. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of disposing a seal element between adjacent tubular tissues to be joined, the method comprising:
-
providing a circular surgical anastomosis device, the circular surgical anastomosis device including;
an anvil assembly having an anvil member and a first shaft; and
a tubular body portion having an annular knife operatively disposed therein and a second shaft disposed radially inward of the annular knife, the first shaft of the anvil assembly being selectively attachable to the second shaft of the tubular body;
inserting the anvil assembly into a first tubular tissue;
inserting the tubular body portion into a second tubular tissue;
disposing a support structure between the first tubular tissue and the second tubular tissue, the seal element comprising a first material and a second material wherein the first material promotes tissue ingrowth and the second material comprises a sealant;
approximating the anvil assembly and tubular body portion with one another so that an end portion of the first tubular tissue, the support structure, and an end portion of the second tubular tissue are disposed between the anvil member and the tubular body portion, the seal element being disposed between the first tubular tissue and the second tubular tissue;
firing the surgical anastomosis device to sever the portions of the first and second tubular tissues disposed radially inward of the annular knife, and to touch the portions of the first and second tubular tissues radially outward of the annular knife against the structure to thereby secure the seal element between the first and second tubular tissues.
