Buttress Retention System for Linear Endostaplers
First Claim
1. An end effector for use with a surgical stapler, the end effector comprising:
- a staple cartridge assembly having a tissue contacting surface, a first side surface extending from the tissue contacting surface, and a second side surface opposite the first side surface;
an anvil assembly having a tissue contacting surface, a first side surface extending from the tissue contacting surface, and a second side surface opposite the first side surface;
the staple cartridge assembly and anvil assembly having proximal and distal attachment zones;
a buttress releasably disposed on the tissue contacting surfaces of each of the staple cartridge and the anvil plate; and
a pair of anchor members affixed to the attachment zones of each of the staple cartridge and anvil plate configured to retain the respective buttress material atop the respective tissue contacting surfaces.
