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 for use with a surgical stapling instrument, wherein the staple cartridge assembly comprises:
a staple cartridge, comprising:
a plurality of staples; and
a cartridge deck; and

a collapsible absorbable lattice positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the collapsible absorbable lattice, and wherein the collapsible absorbable lattice comprises:
a first biocompatible layer;
a second biocompatible layer; and
standing fibers interconnecting the first biocompatible layer and the second biocompatible layer, wherein the standing fibers cooperatively maintain the first biocompatible layer away from the second biocompatible layer, and wherein the standing fibers comprise end portions embedded into the second biocompatible layer.

2. The staple cartridge assembly of claim 1 , wherein the second biocompatible layer comprises a film.

3. The staple cartridge assembly of claim 2 , wherein the collapsible absorbable lattice is releasably securable to the staple cartridge.

4. The staple cartridge assembly of claim 1 , wherein the collapsible absorbable lattice comprises an adhesive for releasably securing the second biocompatible layer to the staple cartridge.

5. The staple cartridge assembly of claim 1 , wherein the end portions are woven into the second biocompatible layer.

6. The staple cartridge assembly of claim 1 , wherein the end portions are knitted into the second biocompatible layer.

7. The staple cartridge assembly of claim 1 , wherein at least one of the first biocompatible layer and the second biocompatible layer is a knitted layer.

8. The staple cartridge assembly of claim 1 , wherein at least one of the first biocompatible layer and the second biocompatible layer is a woven layer.

9. The staple cartridge assembly of claim 1 , wherein the end portions are second end portions, and wherein the standing fibers comprise first end portions embedded into the first biocompatible layer.

10. A staple cartridge assembly for use with a surgical stapling instrument, wherein the staple cartridge assembly comprises:
a staple cartridge, comprising:
a plurality of staples; and
a cartridge deck; and

a collapsible absorbable lattice positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the collapsible absorbable lattice, and wherein the collapsible absorbable lattice comprises:
a first biocompatible layer;
a second biocompatible layer; and
standing fibers extending between the first biocompatible layer and the second biocompatible layer, wherein the standing fibers cooperatively maintain a separation between the first biocompatible layer and the second biocompatible layer, and wherein the standing fibers comprise end portions embedded into the second biocompatible layer.

11. The staple cartridge assembly of claim 10 , wherein the second biocompatible layer comprises a film.

12. The staple cartridge assembly of claim 11 , wherein the collapsible absorbable lattice is releasably securable to the staple cartridge.

13. The staple cartridge assembly of claim 10 , wherein the collapsible absorbable lattice comprises an adhesive for releasably securing the second biocompatible layer to the staple cartridge.

14. The staple cartridge assembly of claim 10 , wherein the end portions are woven into the second biocompatible layer.

15. The staple cartridge assembly of claim 10 , wherein the end portions are knitted into the second biocompatible layer.

16. The staple cartridge assembly of claim 10 , wherein at least one of the first biocompatible layer and the second biocompatible layer is a knitted layer.

17. The staple cartridge assembly of claim 10 , wherein at least one of the first biocompatible layer and the second biocompatible layer is a woven layer.

18. The staple cartridge assembly of claim 10 , wherein the end portions are second end portions, and wherein the standing fibers comprise first end portions embedded into the first biocompatible layer.

19. A collapsible absorbable lattice positionable against a cartridge deck of a staple cartridge of a surgical stapling instrument, wherein staples are deployable from the staple cartridge into tissue grasped against the collapsible absorbable lattice, and wherein the collapsible absorbable lattice comprises:
a first biocompatible layer;
a second biocompatible layer; and
standing fibers extending between the first biocompatible layer and the second biocompatible layer, wherein the standing fibers cooperatively maintain a separation between the first biocompatible layer and the second biocompatible layer, and wherein the standing fibers comprise end portions embedded into the second biocompatible layer.

20. The collapsible absorbable lattice of claim 19 , comprising an adhesive for releasably securing the second biocompatible layer to the staple cartridge.
