Abstract

An end effector for use with a surgical instrument is disclosed which includes a staple cartridge comprising a cartridge body, a plurality of staples, and a longitudinal slot extending longitudinally along a length of the cartridge body. The longitudinal slot includes a first side and a second side opposite the first side. In addition, the end effector includes a cutting member slidably movable along the longitudinal slot and an implantable assembly which includes a first layer and a second layer, wherein the second layer includes a first portion and a second portion spaced apart from the first portion, and wherein the first layer is attached to the first portion and the second portion.

Claims

1. An end effector for use with a surgical instrument, said end effector comprising:

a staple cartridge, comprising;

a cartridge body;

a plurality of staples;

a longitudinal slot extending longitudinally along a length of said cartridge body, said longitudinal slot comprising a first side and a second side opposite said first side; and

a cutting member slidably movable along said longitudinal slot; and

an implantable assembly, comprising;

a first layer; and

a second layer, comprising;

a first portion; and

a second portion spaced apart from said first portion, wherein said first layer is attached to said first portion and said second portion, and wherein said first layer is partially embedded in at least one of said first portion and said second portion.

2. The end effector of claim 1, wherein said first layer is thinner than said second layer.

3. The end effector of claim 1, wherein said first layer comprises a first height, wherein said first portion comprises a second height, and wherein said first height is less than said second height.

4. The end effector of claim 1, wherein said first layer is at least partially disposed over said second layer.

5. The end effector of claim 1, wherein said first layer comprises a film.

6. The end effector of claim 5, wherein said film comprises a plurality of perforations.

7. The end effector of claim 6, wherein the cutting member is configured to cut said film along said plurality of perforations.

8. The end effector of claim 1, wherein said first portion and said second portion define a gap therebetween, and wherein said first layer is configured to bridge said gap.

9. The end effector of claim 8, wherein said first layer is at least partially disposed across said gap.

10. The end effector of claim 1, wherein said first layer is comprised of a first material, and wherein said second layer is comprised of a second material different than said first material.

11. The end effector of claim 10, wherein said first material comprises a first biocompatible material, and wherein said second material comprises a second biocompatible material.

12. An end effector for use with a surgical instrument, said end effector comprising:

a staple cartridge, comprising;

a cartridge body;

a plurality of staples;

a longitudinal slot extending longitudinally along a length of said cartridge body, said longitudinal slot comprising a first side and a second side opposite said first side; and

a cutting member slidably movable along said longitudinal slot; and

an implantable assembly, comprising;

a first layer; and

a second layer, comprising;

a first portion extending at least partially along said first side of said longitudinal slot; and

a second portion extending at least partially along said first side of said longitudinal slot, wherein said second portion is spaced apart from said first portion, wherein said first layer extends between said first portion and said second portion, and wherein said first layer is partially positioned within at least one of said first portion and said second portion.

13. The end effector of claim 12, wherein said first portion and said second portion define a gap therebetween, and wherein said first layer bridges said gap.

14. The end effector of claim 12, wherein said first layer is at least partially disposed over said longitudinal slot.
