Folded buttress for use with a surgical apparatus
First Claim
1. An end effector for use with a surgical apparatus, the end effector comprising:
- a staple cartridge having a tissue contacting surface defining a central longitudinal slot;
an anvil plate having a tissue contacting surface defining a central longitudinal slot; and
a surgical buttress overlying and releasably retained on the tissue contacting surface of the staple cartridge or the anvil plate, the surgical buttress having a first longitudinal portion, a second longitudinal portion and middle longitudinal portion between the first and second longitudinal portions, the surgical buttress and including a proximal portion with a proximal edge and a distal portion with a distal edge,wherein the middle longitudinal portion is folded and configured to fit within the central longitudinal slot of the staple cartridge or the anvil plate, and wherein at least one of the proximal portion or the distal portion of the surgical buttress is folded against the bottom surface of the surgical buttress, and positioned immediately adjacent the bottom surface of the surgical buttress and the tissue contacting surface of the staple cartridge or the anvil plate on which the surgical buttress is releasably retained.

Abstract
An end effector for use with a surgical apparatus. The end effector comprising a staple cartridge having a tissue contacting surface defining a central longitudinal slot and an anvil plate having a tissue contacting surface defining a central longitudinal slot. A folded surgical buttress configured to overlie each of the tissue contacting surfaces of the staple cartridge and anvil plate and configured to retain the surgical buttress to the tissue contacting surfaces of each of the staple cartridge and anvil plate. The surgical buttress having a first longitudinal portion, a second longitudinal portion, and middle longitudinal portion between the first and second longitudinal portions, wherein the middle longitudinal portion is folded and configured to fit within the central longitudinal slot of each of the staple cartridge and anvil plate.

3. A surgical stapling apparatus, comprising:
-
a handle; an elongate tubular member extending distally from the handle; and a staple cartridge operably coupled to a distal end of the elongated tubular member, the staple cartridge comprising;
a cartridge body including a tissue contacting surface defining a plurality of staple retaining slots and having a central longitudinal slot;
a staple disposed within each staple retaining slot of the cartridge body; and
a surgical buttress overlying and releasably retained on the tissue contacting surface of the staple cartridge, the surgical buttress defining a bottom surface, and including a proximal portion with a proximal edge and a distal portion with a distal edge, wherein the proximal portion of the surgical buttress is folded against the bottom surface such that the proximal edge is immediately adjacent the bottom surface of the surgical buttress, and wherein the distal portion of the surgical buttress is folded against the bottom surface such that the distal edge is immediately adjacent the bottom surface of the surgical buttress and the tissue contacting surface of the staple cartridge.
