Abstract

A fastener cartridge can comprise a cartridge body comprising fastener cavities, fasteners at least partially stored within the cartridge body, and a layer positioned over the cartridge body. The cartridge body can include a proximal end and a distal end. Similarly, the layer can include a proximal end and a distal end. The distal end of the layer can extend distally with respect to the distal end of the cartridge body. Furthermore, the layer can include a distal portion which extends distally with respect to the fastener cavities defined in the cartridge body. This distal portion can be positioned against the tissue being fastened and can flexibly support the tissue after the layer has been implanted against the tissue. The layer may include a proximal portion which extends proximally with respect to the fastener cavities which can flexibly support the tissue after the layer has been implanted.

Claims

1. A staple cartridge, comprising:

a cartridge body comprising a deck;

a plurality of staples removably stored within said cartridge body; and

an implantable layer assembly positioned over said deck, wherein said implantable layer assembly comprises;

a compensation layer configured to be at least partially captured within said staples when said staples are moved from an unfired position to a fired position, wherein said compensation layer comprises a distal compensation end and a first proximal-to-distal length; and

an overlap layer extending from and overlapping at least a portion of said compensation layer, wherein said overlap layer comprises a distal overlap end and a second proximal-to-distal length, wherein said second proximal-to-distal length is longer than said first proximal-to-distal length, wherein said distal overlap end extends distally beyond said distal compensation end, and wherein said overlap layer is configured to overlap an adjacent implanted implantable layer.

2. The staple cartridge of claim 1, wherein said compensation layer is comprised of a compressible foam.

3. The staple cartridge of claim 1, wherein said deck comprises a distal deck end, and wherein said distal overlap end extends beyond said distal deck end and said distal compensation end.

4. The staple cartridge of claim 1, wherein said overlap layer and said compensation layer comprise a laminate material.

5. The staple cartridge of claim 1, wherein said overlap layer comprises a flexible end member extending from said compensation layer.

6. The staple cartridge of claim 1, wherein said overlap layer is adhered to said portion of said compensation layer.

7. A staple cartridge, comprising:

a cartridge body comprising a deck;

a plurality of staples removably stored within said cartridge body; and

an implantable layer positioned over said deck, wherein said implantable layer comprises;

a compensation portion configured to be captured within said staples when said staples are moved from an unfired position to a fired position, wherein said compensation portion comprises a distal compensation end; and

an overlap portion extending from and overlapping at least a portion of said compensation portion, wherein said overlap portion comprises a tissue abutment portion extending distally beyond said distal compensation end, and wherein said tissue abutment portion of said overlap portion is configured to overlap the compensation portion of an adjacent implanted implantable layer.

8. The staple cartridge of claim 7, wherein said compensation portion is comprised of a compressible foam.

9. The staple cartridge of claim 7, wherein said deck comprises a distal deck end, wherein said overlap portion comprises a distal overlap end, and wherein said distal overlap end extends beyond said distal deck end and said distal compensation end.

10. The staple cartridge of claim 7, wherein said overlap portion and said compensation portion comprise a laminate material.

11. The staple cartridge of claim 7, wherein said overlap portion comprises a flexible end member extending from said compensation portion.

12. The staple cartridge of claim 7, wherein said overlap portion is adhered to said portion of said compensation portion.

16. The staple cartridge of claim 12, wherein said compensation portion comprises a distal compensation end, wherein said overlap portion comprises a distal overlap end, and wherein said distal overlap end extends beyond said distal end of said tissue-supporting deck and said distal compensation end.

13. A staple cartridge, comprising:

a cartridge body comprising a tissue-supporting deck, wherein said tissue-supporting deck comprises a proximal end, a distal end, and a plurality of staple cavities defined between said proximal end and said distal end;

a plurality of staples removably stored within said cartridge body; and

an implantable layer positioned over said tissue-supporting deck, wherein said staples are configured to capture at least a portion of said implantable layer therein when said staples are moved from an unfired position to a fired position, and wherein said implantable layer comprises;

a body comprising a distal body end; and

a tissue support portion overlapping a portion of said body and which extends distally beyond said distal end of said tissue-supporting deck and distally beyond said distal body end.

14. The staple cartridge of claim 13, wherein said implantable layer comprises:

a compensation portion configured to be captured within said staples; and

an overlap portion extending from said compensation portion, wherein said overlap portion is configured to overlap the implantable layer of an adjacent implanted implantable layer.

15. The staple cartridge of claim 14, wherein said compensation portion is comprised of a compressible foam.

17. The staple cartridge of claim 14, wherein said overlap portion and said compensation portion comprise a laminate material.

18. The staple cartridge of claim 14, wherein said overlap portion comprises a flexible end member extending from said compensation portion.

19. The staple cartridge of claim 13, wherein said tissue support portion is adhered to said portion of said body.
