Buttress retention system for linear endostaplers
First Claim
1. An anvil assembly of a jaw of a surgical stapler, the anvil assembly comprising:
- an anvil plate defining;
a tissue contacting surface defining a plurality of staple forming slots and a central longitudinal extending knife slot; and
a first side surface and a second side surface opposite the first side surface;
wherein the first and second side surfaces each have polymeric overmolded zones integrally formed with the anvil plate and disposed near a proximal portion and a distal portion thereof, wherein at least one polymeric overmolded zone of the polymeric overmolded zones is textured.

Abstract
An end effector for use with a surgical stapler comprising a staple cartridge having a tissue contacting surface, a first side surface, and a second side surface opposite the first side surface, an anvil plate having a tissue contacting surface, a first side surface, and a second side surface opposite the first side surface, wherein the first and second side surfaces of each of the staple cartridge and anvil plate have overmolded zones, a buttress releasably disposed on the tissue contacting surfaces of each of the staple cartridge and the anvil plate, and a pair of sutures wherein each suture is bonded to the respective overmolded zones of the first and second side surfaces configured to retain the respective buttress atop the respective tissue contacting surfaces.

13. An anvil assembly of a jaw of a surgical stapler, the anvil assembly comprising:
-
an anvil plate defining; a tissue contacting surface defining a plurality of staple forming slots and a central longitudinal extending knife slot; and a first side surface and a second side surface opposite the first side surface; wherein the first and second side surfaces each have polymeric overmolded zones integrally formed with the anvil plate and disposed near a proximal portion and a distal portion thereof; a buttress disposed on the tissue contacting surface of the anvil plate; and a proximal suture traversing across the proximal portion of the anvil plate, and a distal suture traversing across the distal portion of the anvil plate, wherein ends of the proximal and distal sutures are secured to the polymeric overmolded zones to secure the buttress to the tissue contacting surface of the anvil plate.
