Abstract

A fastener cartridge can comprise fastener cavities arranged in longitudinal rows. A first fastener having a first configuration and a second fastener having a second configuration can be stored within a longitudinal row. First fasteners having a first configuration can be stored within a first longitudinal row and second fasteners having a second configuration can be stored within a second longitudinal row. Each first fastener can have a proximal leg, or leg portion, extending at a first proximal angle and a distal leg, or leg portion, extending at a first distal angle and each second fastener can have a proximal leg, or leg portion, extending at a second proximal angle and a distal leg, or leg portion, extending at a second distal angle. The first proximal angle can be different than the second proximal angle and/or the first distal angle can be different than the second distal angle.

First claim

What is claimed is:

1. A fastener cartridge, comprising:
a cartridge body, comprising:
a proximal end;
a distal end;
a deck; and
a longitudinal row of fastener cavities defined in the deck, the longitudinal row of fastener cavities comprising a proximal-most fastener cavity and a distal-most fastener cavity;

a layer, comprising:
a plurality of first connectors to releasably retain the layer to the deck, wherein the first connectors are positioned between the proximal-most fastener cavity and the distal-most fastener cavity; and
a second connector to releasably retain the layer to the deck, wherein the second connector is positioned distal to the distal-most fastener cavity, and wherein the second connector is different from the plurality of first connectors.

2. The fastener cartridge of claim 1 , wherein the plurality of first connectors comprises a plurality of apertures.

3. The fastener cartridge of claim 2 , wherein the cartridge body further comprises a plurality of projections extending from the deck into the plurality of apertures, and wherein an interference fit at a plurality of locations releasably retains the layer to the deck.

4. The fastener cartridge of claim 1 , wherein the second connector comprises a plurality of second connectors, and wherein each second connector comprises an adhesive.

5. The fastener cartridge of claim 1 , wherein the layer further comprises a tissue thickness compensator.

6. The fastener cartridge of claim 1 , wherein the cartridge body further comprises a longitudinal slot defined in the deck, and wherein the layer extends over the longitudinal slot.

7. The fastener cartridge of claim 6 , wherein the plurality of first connectors comprises a first plurality of first connectors and a second plurality of first connectors, wherein the first plurality of first connectors is positioned on a first side of the longitudinal slot, and wherein the second plurality of first connectors is positioned on a second side of the longitudinal slot.

8. A fastener cartridge, comprising:
a cartridge body, comprising:
a proximal end;
a distal end;
a deck; and
a longitudinal row of fastener cavities defined in the deck;

a layer, comprising:
a plurality of first connectors to releasably retain the layer to the deck, wherein the first connectors are positioned at least partially within the longitudinal row of fastener cavities; and
a second connector to releasably retain the layer to the deck, wherein the second connector is positioned distal to the longitudinal row of fastener cavities, and wherein the second connector is different from the plurality of first connectors.

9. The fastener cartridge of claim 8 , wherein the plurality of first connectors comprises a plurality of apertures.

10. The fastener cartridge of claim 9 , wherein the cartridge body further comprises a plurality of projections extending from the deck into the plurality of apertures, and wherein an interference fit at a plurality of locations releasably retains the layer to the deck.

11. The fastener cartridge of claim 8 , wherein the second connector comprises an adhesive.

12. The fastener cartridge of claim 8 , wherein the layer further comprises at least one of a buttress material or a tissue thickness compensator.

13. The fastener cartridge of claim 8 , wherein the cartridge body further comprises a longitudinal slot defined in the deck, wherein the layer extends over the longitudinal slot, wherein the plurality of first connectors comprises a first plurality of first connectors and a second plurality of first connectors, wherein the first plurality of first connectors is positioned on a first side of the longitudinal slot, and wherein the second plurality of first connectors is positioned on a second side of the longitudinal slot.

14. A fastener cartridge, comprising:
a cartridge body, comprising:
a proximal end;
a distal end;
a deck; and
a longitudinal row of fastener cavities defined in the deck, the longitudinal row of fastener cavities comprising a proximal-most fastener cavity and a distal-most fastener cavity;

a layer, comprising:
a plurality of first attachment portions to releasably retain the layer to the deck, wherein the first attachment portions are positioned between the proximal-most fastener cavity and the distal-most fastener cavity; and
a second attachment portion to releasably retain the layer to the deck, wherein the second attachment portion is positioned distal to the distal-most fastener cavity, and wherein the second attachment portion and the plurality of first attachment portions comprise different geometries.

15. The fastener cartridge of claim 14 , wherein the plurality of first attachment portions comprises a plurality of apertures.

16. The fastener cartridge of claim 15 , wherein the cartridge body further comprises a plurality of projections extending from the deck into the plurality of apertures, and wherein an interference fit at a plurality of locations releasably retains the layer to the deck.

17. A fastener cartridge, comprising:
a cartridge body, comprising a deck and a longitudinal row of fastener cavities defined in the deck, the longitudinal row of fastener cavities comprising a proximal-most fastener cavity and a distal-most fastener cavity;
a layer;
a first connector positioned between the proximal-most fastener cavity and the distal-most fastener cavity to releasably retain the layer to the deck; and
a second connector to releasably retain the layer to the deck, wherein the second connector is positioned distal to the distal-most fastener cavity, and wherein the second connector is different than the first connector.

18. The fastener cartridge of claim 17 , wherein the layer further comprises a tissue-facing surface, and wherein the second connector extends over a portion of the tissue-facing surface.

19. The fastener cartridge of claim 18 , wherein the layer further comprises a deck-facing surface, and wherein the first connector is positioned between the deck and the deck-facing surface.

20. The fastener cartridge of claim 19 , further comprising an aperture extending into the layer from the deck-facing surface to form the first connector.

21. The fastener cartridge of claim 17 , further comprising an adhesive intermediate the layer and the deck.

22. The fastener cartridge of claim 17 , further comprising a suture to releasably adhere the layer to the deck.

23. The fastener cartridge of claim 17 , wherein the deck comprises a laterally-stepped deck comprising a plurality of steps, and wherein the longitudinal row of fastener cavities - 6 . extends along a step of the plurality of steps.

24. The fastener cartridge of claim 23 , wherein the laterally-stepped deck further comprises a plurality of projections.

25. The fastener cartridge of claim 17 , further comprising a plurality of staples removably positioned in the cartridge body.
