Abstract

A fastener cartridge assembly includes a plurality of fasteners and a layer configured to be captured by the fasteners. In addition, the layer includes a tissue contacting surface which includes a plurality of cleats, and/or any other suitable structures, configured to reduce slippage between the layer and the patient tissue. In various embodiments, the layer can include traction features extending therefrom.

Claims

1. A staple cartridge assembly, comprising:

a cartridge body, comprising;

a deck; and

a plurality of staples; and

a layer configured to be captured by said staples, wherein said layer comprises a tissue contacting surface, and wherein said tissue contacting surface comprises a plurality of cleats configured to reduce tissue slippage relative to said layer.

2. The staple cartridge assembly of claim 1, wherein said layer comprises a tissue thickness compensator.

3. The staple cartridge assembly of claim 2, wherein said tissue thickness compensator comprises internal compression features within said layer.

4. The staple cartridge assembly of claim 1, wherein said cleats comprise micro-structures.

5. The staple cartridge assembly of claim 1, wherein said cleats comprise nano-structures.

6. The staple cartridge assembly of claim 1, wherein said cleats comprise pillars.

7. The staple cartridge assembly of claim 1, wherein said layer comprises a biocompatible film, and wherein said cleats are compression molded into said biocompatible film.

8. The staple cartridge assembly of claim 1, wherein said cleats are arranged in a pattern.

9. A surgical stapler, comprising:

an anvil; and

a staple cartridge assembly, comprising;

a cartridge body, comprising;

a deck; and

a plurality of staples; and

a layer configured to be captured by said staples, said layer comprising a tissue contacting surface, wherein said tissue contacting surface comprises traction means for improving traction against tissue.

10. The surgical stapler of claim 9, wherein said layer comprises a tissue thickness compensator.

11. The surgical stapler of claim 10, wherein said tissue thickness compensator comprises internal compression features within said layer.

12. The surgical stapler of claim 9, wherein said traction means comprises micro-structures.

13. The surgical stapler of claim 9, wherein said traction means comprises nano-structures.

14. The surgical stapler of claim 9, wherein said traction means comprises a plurality of pillars.

15. The surgical stapler of claim 9, wherein said layer comprises a biocompatible film, and wherein said traction means are compression molded into said biocompatible film.

16. The surgical stapler of claim 9, wherein said traction means comprises a plurality of protrusions arranged in a pattern.

17. A staple cartridge assembly, comprising:

a cartridge body, comprising;

a deck; and

a plurality of staples movable between unfired positions and fired positions, said staples comprising staple legs and staple bases; and

a tissue thickness compensator configured to be captured by said staples, said tissue thickness compensator comprising;

a plurality of first portions comprising a first thickness; and

a plurality of second portions comprising a second thickness, wherein said first thickness is different from said second thickness, wherein said first portions are configured to be captured between said staple legs and said staple bases when said staples are in their fired positions, and wherein said second portions are configured and arranged such that they are not captured between said staple legs and said staple bases when said staples are in their fired positions.

18. The staple cartridge assembly of claim 17, wherein said first thickness is greater than said second thickness.

19. The staple cartridge assembly of claim 17, wherein said first portions comprise protrusions configured to be captured between said staple legs and said staple bases when said staples are in their fired positions.

20. The staple cartridge assembly of claim 17, wherein said first thickness is greater than said second thickness.
