Surgical stapling apparatus
First Claim
1. A surgical stapling apparatus, comprising:
- a cartridge assembly defining a tissue contacting surface and a longitudinally extending elongate slot;
an anvil assembly defining a tissue contacting surface and a longitudinally extending elongate slot; and
a surgical buttress releasably secured to at least one of the tissue contacting surface of the cartridge assembly and the tissue contacting surface of the anvil assembly by at least one anchor, wherein each buttress defines a notch formed in a proximal edge thereof and substantially aligned with the longitudinally extending elongate slot of a respective cartridge assembly and anvil assembly,at least one of the cartridge assembly and the anvil assembly including;
a pair of constricting slots formed in a respective side edge thereof,wherein a suture extends across the pair of constricting slots of the at least one of the cartridge assembly and the anvil assembly for securing the surgical buttress thereto.

7. A surgical stapling apparatus, comprising:
-
a cartridge assembly defining a tissue contacting surface; an anvil assembly defining a tissue contacting surface, wherein the tissue contacting surface of at least one of the cartridge assembly and the anvil assembly includes a grip enhancing feature formed thereon; each of the cartridge assembly and the anvil assembly defining a longitudinally extending elongate slot and the tissue contacting surface of at least one of the cartridge assembly and the anvil assembly including at least one of a distal grip enhancing feature disposed distal of the longitudinally extending elongate slot and a proximal grip enhancing feature disposed on opposed sides of the longitudinally extending elongate slot, wherein each grip enhancing feature is a projection extending from the tissue contacting surface; and a surgical buttress releasably secured to at least one of the tissue contacting surface of the cartridge assembly and the tissue contacting surface of the anvil assembly by at least one anchor, wherein a position of the surgical buttress relative to a respective cartridge assembly and anvil assembly is better maintained as compared to a cartridge assembly and an anvil assembly devoid of the grip enhancing feature. - View Dependent Claims (8)
