Abstract

A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

First claim

What is claimed is:

1. A staple cartridge assembly, comprising:
a cartridge body, comprising:
a deck;
a longitudinal slot defining a first side of said cartridge body and a second side of said cartridge body; and
a plurality of staple cavities defined in said deck;

a plurality of staples stored within said staple cavities; and
an implantable layer assembly, comprising:
a first layer positioned on said first side of said cartridge body; and
a second layer positioned on said second side of said cartridge body, wherein said first layer and said second layer each comprise:
a bioabsorbable outer layer comprising a top and a bottom; and
reinforcement fibers extending between said top and said bottom, wherein said reinforcement fibers are configured to maintain a distance between said top and said bottom.

2. The staple cartridge assembly of claim 1 , wherein said reinforcement fibers are comprised of a non-synthetic material.

3. The staple cartridge assembly of claim 2 , wherein said non-synthetic material comprises at least one of a mesh, a non-woven material, a woven material, a film, or a melt-blown material.

4. The staple cartridge assembly of claim 1 , wherein said bioabsorbable outer layer is comprised of a synthetic absorbable material.

5. The staple cartridge assembly of claim 1 , wherein said first layer and said second layer extend at least substantially parallel to each other.

6. The staple cartridge assembly of claim 1 , wherein said reinforcement fibers are substantially parallel to each other.

7. The staple cartridge assembly of claim 1 , wherein said reinforcement fibers are oriented at an angle relative to said top and said bottom.

8. The staple cartridge assembly of claim 1 , wherein said implantable layer assembly further comprises a plurality of bridge members extending between said first layer and said second layer over said longitudinal slot.

9. A staple cartridge assembly, comprising:
a cartridge body, comprising:
a deck;
a longitudinal slot defining a first side of said cartridge body and a second side of said cartridge body; and
a plurality of staple cavities defined in said deck;

a plurality of staples stored within said staple cavities; and
an implantable layer assembly, comprising:
a first layer positioned on said first side of said cartridge body; and
a second layer positioned on said second side of said cartridge body, wherein said first layer and said second layer each comprise:
a bioabsorbable exterior shell comprising a top and a bottom; and
spacer fibers interconnecting said top and said bottom, wherein said spacer fibers are configured to maintain a space between said top and said bottom.

10. The staple cartridge assembly of claim 9 , wherein said spacer fibers are comprised of a non-synthetic material.

11. The staple cartridge assembly of claim 10 , wherein said non-synthetic material comprises at least one of a mesh, a non-woven material, a woven material, a film, or a melt-blown material.

12. The staple cartridge assembly of claim 9 , wherein said bioabsorbable exterior shell is comprised of a synthetic absorbable material.

13. The staple cartridge assembly of claim 9 , wherein said first layer and said second layer extend at least substantially parallel to each other.

14. The staple cartridge assembly of claim 9 , wherein said spacer fibers are substantially parallel to each other.

15. The staple cartridge assembly of claim 9 , wherein said spacer fibers are oriented at an angle relative to said top and said bottom.

16. The staple cartridge assembly of claim 9 , wherein said implantable layer assembly further comprises a plurality of bridge members extending between said first layer and said second layer over said longitudinal slot.
