Abstract

A fastener cartridge including a cartridge body and a layer mounted to said cartridge body is disclosed. The cartridge body can include projections extending therefrom and the layer can include apertures which correspond to the projections. The projections and the apertures can form a releasable interference fit therebetween to secure the layer to the cartridge body.

Claims

1. A fastener cartridge, comprising:

a cartridge body, comprising;

a deck;

fastener cavities defined in said deck;

projections extending from said deck;

fasteners removably stored in said fastener cavities;

a layer of material supported by said deck, comprising;

a layer body; and

apertures defined in said layer body, wherein said projections are positioned in said apertures.

2. The fastener cartridge of claim 1, wherein said projections and said apertures are sized and configured such that there is an interference fit between said projections and said apertures, and wherein said interference fit releasably retains said layer of material to said cartridge body.

3. The fastener cartridge of claim 1, wherein said projections are positioned intermediate said fastener cavities.

4. The fastener cartridge of claim 1, wherein said projections extend said fastener cavities above said deck.

5. The fastener cartridge of claim 1, wherein said projections are configured to guide said fasteners when said fasteners are ejected from said fastener cavities.

6. The fastener cartridge of claim 1, wherein said apertures comprise through holes.

7. The fastener cartridge of claim 1, wherein said layer comprises a buttress material.

8. The fastener cartridge of claim 1, wherein said layer comprises a tissue thickness compensator.

9. A fastener cartridge, comprising:

a cartridge body, comprising;

a deck;

fastener cavities defined in said deck, wherein each said fastener cavity comprises a proximal end and a distal end;

proximal projections extending from said deck, wherein each said proximal projection is positioned at a said proximal end of a said fastener cavity; and

distal projections extending from said deck, wherein each said distal projection is positioned at a said distal end of a said fastener cavity;

fasteners removably stored in said fastener cavities;

a layer of material supported by said deck, comprising;

a layer body;

proximal apertures defined in said layer body, wherein each said proximal aperture is configured to receive a said proximal projection; and

distal apertures defined in said layer body, wherein each said distal aperture is configured to receive a said distal projection.

10. The fastener cartridge of claim 9, wherein said distal projections and said distal apertures are sized and configured such that there is an interference fit therebetween, wherein said proximal projections and said proximal apertures are sized and configured such that there is an interference fit therebetween, and wherein said interference fits releasably retain said layer of material to said cartridge body.

11. The fastener cartridge of claim 9, wherein said distal projections extend said fastener cavities above said deck, and wherein said distal projections are configured to guide said fasteners when said fasteners are ejected from said fastener cavities.

12. The fastener cartridge of claim 9, wherein said proximal projections extend said fastener cavities above said deck, and wherein said proximal projections are configured to guide said fasteners when said fasteners are ejected from said fastener cavities.

13. The fastener cartridge of claim 9, wherein said proximal apertures and said distal apertures comprise through holes.

14. The fastener cartridge of claim 9, wherein said layer comprises a buttress material.

15. The fastener cartridge of claim 9, wherein said layer comprises a tissue thickness compensator.

16. A fastener cartridge, comprising:

a cartridge body, comprising;

a deck;

fastener cavities defined in said deck;

an array of fastener cavity extenders extending from said deck;

fasteners removably stored in said fastener cavities;

a layer of material supported by said deck, comprising;

a layer body; and

an array of apertures defined in said layer body, wherein said array of apertures matches said array of fastener cavity extenders.
