a first adhesive tape disposed over the central longitudinal slot of the staple cartridge and not covering the staple retaining slots of the staple cartridge, the first adhesive tape secured to the tissue contacting surface of the staple cartridge at locations surrounding edges of the central longitudinal slot to retain the first surgical buttress atop the tissue contacting surface of the staple cartridge.
2. The end effector of claim 1 , wherein the first surgical buttress is laser welded to the first adhesive tape.
3. The end effector of claim 1 , wherein the first adhesive tape extends longitudinally between a proximal end and a distal end of the tissue contacting surface of the staple cartridge.
4. A staple cartridge for use with a surgical stapling apparatus, the staple cartridge comprising:
a cartridge body including a tissue contacting surface defining a plurality of staple retaining slots and having a central longitudinal slot;
a staple disposed within each staple retaining slot of the cartridge body;
a surgical buttress releasably disposed on the tissue contacting surface of the cartridge body; and
an adhesive tape disposed over the central longitudinal slot of the cartridge body and not covering the plurality of staple retaining slots of the cartridge body, the adhesive tape secured to the tissue contacting surface of the cartridge body at locations surrounding edges of the central longitudinal slot to retain the surgical buttress atop the tissue contacting surface of the cartridge body.
5. The staple cartridge of claim 4 , wherein the surgical buttress is laser welded to the adhesive tape.
6. The staple cartridge of claim 4 , wherein the adhesive tape extends longitudinally between a proximal end and a distal end of the tissue contacting surface of the cartridge body.
7. A surgical stapling apparatus, comprising:
a housing;
an end effector secured to the housing, the end effector including a staple cartridge assembly having a tissue contacting surface and staple retaining slots, and an anvil assembly having a tissue contacting surface, each of the staple cartridge assembly and the anvil assembly having a central longitudinal slot;
a first surgical buttress releasably disposed on the tissue contacting surface of the staple cartridge assembly; and
a first adhesive tape disposed over the central longitudinal slot of the staple cartridge assembly and not covering the staple retaining slots of the cartridge body, the first adhesive tape secured to the tissue contacting surface of the staple cartridge assembly at locations surrounding edges of the central longitudinal slot to retain the first surgical buttress atop the tissue contacting surface of the staple cartridge assembly.
8. The surgical stapling apparatus of claim 7 , wherein the first surgical buttress is laser welded to the first adhesive tape.
9. The surgical stapling apparatus of claim 7 , wherein the first adhesive tape extends longitudinally between a proximal end and a distal end of the tissue contacting surface of the staple cartridge assembly.
