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.

Claims

1. (canceled)

2. A surgical stapling instrument, comprising:

an end effector assembly having a staple cartridge with a tissue contacting surface defining a central longitudinal slot, and an anvil plate having a tissue contacting surface defining a central longitudinal slot; and

a surgical buttress overlying the tissue contacting surface of the staple cartridge or the anvil plate and retained to the tissue contacting surface, the surgical buttress having a first longitudinal portion, a second longitudinal portion, and

a middle longitudinal portion between the first and second longitudinal portions, the first and second longitudinal portions being folded so as to lie adjacent a bottom surface of the surgical buttress, and at least one notch disposed along the first longitudinal portion and at least one notch disposed along the second longitudinal portion.

3. The surgical stapling instrument of claim 2, further comprising sutures retaining the surgical buttress to the tissue contacting surface.

4. The surgical stapling instrument of claim 3, wherein the sutures engage the surgical buttress at the at least one notch along the first longitudinal portion and the at least one notch along the second longitudinal portion.

5. The surgical stapling instrument of claim 2, wherein a portion of the surgical buttress is received in the central longitudinal slot of the staple cartridge or the anvil plate.

6. The surgical stapling instrument of claim 5, wherein the surgical buttress is heat formed or cold folded into a contoured shape for receipt in the central longitudinal slot prior to assembly with the tissue contacting surface.

7. The surgical stapling instrument of claim 2, wherein the middle longitudinal portion is planar and lies on the tissue contacting surface.
