Abstract

A surgical stapling apparatus includes a staple anvil and a staple cartridge having a working surface, one or more rows of individual staple slots formed in the working surface, a knife track formed along a length of the working surface, and a plurality of surgical staples individually disposed within the individual staple slots. The apparatus further includes an actuation sled having a knife and being configured and adapted to movably position the knife axially within the knife track. The apparatus also includes a wound closure material applicator assembly having a needle secured to the knife to dispense a quantity of wound closure material along a length of the knife track as the actuation sled and knife are moved therealong.

Claims
