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 there along.

(canceled)
A surgical stapling apparatus for enhancing one or more properties of body tissue that is or is to be repaired or joined, the surgical stapling apparatus comprising:
- a staple anvil positioned on a distal end of the stapling apparatus and having a longitudinal knife track;
- a staple cartridge positioned adjacent the distal end of the stapling apparatus, the staple cartridge and staple anvil being juxtaposable relative to each other, the staple cartridge including a plurality of surgical staples individually disposed within individual staple slots formed in rows in the staple cartridge, and having a longitudinal knife slot formed between adjacent rows of staples;
- a driving member for firing the surgical staples from the individual staple slots and against the staple anvil;
- a knife blade structure including a knife blade receivable in and axially movable along the rows of staples;
- and
- a wound closure material applicator assembly operatively associated with the stapling apparatus, the assembly including:
- a channel with an orifice;
- and
- a conduit in fluid communication with the channel, wherein axial movement of the knife blade structure through the knife track and knife slot axially advances the knife blade structure to permit the orifice to dispense wound closure material from the orifice into an area extending along the rows of staples axially.
A surgical stapling apparatus for enhancing one or more properties of body tissue that is or is to be repaired or joined, the surgical stapling apparatus comprising:
- a staple anvil positioned on a distal end of the stapling apparatus and having a longitudinal knife track;
- a staple cartridge positioned adjacent the distal end of the stapling apparatus, the staple anvil and staple cartridge being juxtaposable relative to each other, the staple cartridge including:
- a working surface;
- one or more rows of individual staple slots formed in the working surface;
- a knife slot formed along a length of the working surface and between adjacent rows of staples;
- and
- a plurality of surgical staples individually disposed within the individual staple slots;
- a driving member translatably receivable in the staple cartridge for firing the surgical staples from the individual staple slots and against the staple anvil, the driving member including an actuation sled having a knife operatively connected thereto, the actuation sled being configured and adapted to position the knife to be axially movable along a staple line defined by the rows of staples;
- and
- a wound closure material applicator assembly including an applicator having an orifice, and configured to dispense a quantity of wound closure material from the orifice into an area extending along the staple line axially as the knife moves along the length of the knife track and the knife slot.
In a surgical stapling apparatus for enhancing one or more properties of body tissue that is or is to be repaired or joined, wherein the surgical stapling apparatus includes a staple anvil positioned on a distal end of the stapling apparatus, a staple cartridge positioned adjacent the distal end of the stapling apparatus, the staple cartridge including a working surface defining a knife slot formed along a length thereof and between adjacent rows of staples formed in the working surface, a driving member translatably receivable in the staple cartridge and including an actuation sled having a knife structure operatively connected thereto and positioned within the knife slot;
- the improvement comprising:
- a wound closure material applicator assembly configured to dispense a quantity of wound closure material into an area extending axially along a staple line defined by the rows of staples, as the knife structure moves axially along the staple line.
