Abstract

A fastener cartridge can comprise a compressible, collapsible, and/or crushable cartridge body and fasteners embedded within the cartridge body which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein the first jaw can be positioned opposite a second jaw, or anvil. The anvil can be engaged with the fastener cartridge to compress, collapse, and/or crush the cartridge body and deform, or otherwise deploy, the fasteners contained therein. As the fasteners are deformed or deployed, the fasteners can capture at least a portion of the cartridge body therein along with at least a portion of the tissue being fastened. In various embodiments, at least portions of the fasteners can extend outside of the cartridge body. The first jaw can comprise support features, such as slots, for example, which can directly support such external portions of the fasteners.

Claims

1. A surgical stapling system, comprising:

a staple cartridge channel, comprising;

a bottom support surface comprising a plurality of staple supports;

a first lateral cartridge support surface extending from said bottom support surface; and

a second lateral cartridge support surface extending from said bottom surface; and

a staple cartridge removably positioned within said staple cartridge channel, said staple cartridge comprising;

a compressible staple cartridge body positioned intermediate said first lateral cartridge support and said second lateral cartridge support; and

a plurality of staples embedded within said staple cartridge body, wherein each said staple is aligned with a said staple support.

2. The surgical stapling system of claim 1, wherein said compressible staple cartridge body comprises a bottom surface, wherein each said staple comprises a base and a deformable leg extending from said base, and wherein said bases of said staples are positioned below said bottom surface.

3. The surgical stapling system of claim 2, wherein said staple cartridge further comprises a water impermeable layer surrounding said compressible staple cartridge body.

4. The surgical stapling system of claim 3, wherein said layer extends between said staple bases and said staple supports.

5. The surgical stapling system of claim 1, wherein said staple supports comprise troughs in said bottom support surface.

6. A surgical stapling system, comprising:

a staple cartridge attachment portion comprising a bottom support surface comprising a plurality of staple supports;

a staple cartridge removably positioned within said staple cartridge channel, said staple cartridge comprising;

a compressible staple cartridge body; and

a plurality of staples, wherein each said staple comprises a base and a deformable leg extending from said base, wherein said deformable legs are embedded within said compressible staple cartridge body, and wherein each said staple is aligned with a said staple support; and

an anvil movable between an open position, an intermediate position, and a closed position, wherein said anvil is configured to engage and compress said compressible staple cartridge body when said anvil is in said intermediate position.

7. The surgical stapling system of claim 6, wherein said staple cartridge comprises:

a bottom;

a top; and

a staple cartridge height defined between said top and said bottom, wherein said staple cartridge attachment portion comprises a bottom support surface, wherein said anvil comprises a tissue-contacting surface, wherein a gap distance is defined between said bottom support surface and said tissue-contacting surface when said anvil is in said closed position, and wherein said gap distance is shorter than said staple cartridge height.

8. The surgical stapling system of claim 6, wherein said compressible staple cartridge body comprises a bottom surface, wherein each said staple comprises a base and a deformable leg extending from said base, and wherein said bases of said staples are positioned below said bottom surface.

9. The surgical stapling system of claim 8, wherein said staple cartridge further comprises a water impermeable layer surrounding said compressible staple cartridge body.

10. The surgical stapling system of claim 9, wherein said layer extends between said staple bases and said staple supports.

11. The surgical stapling system of claim 6, wherein said staple supports comprise troughs in said bottom support surface.

12. The surgical stapling system of claim 6, wherein said staple cartridge attachment portion comprises lateral cartridge support surface configured to inhibit movement of said staple cartridge relative to said bottom support surface.

13. The surgical stapling system of claim 6, wherein said anvil is configured to engage said staple legs when said anvil is in said intermediate position.

14. A staple cartridge configured to be removably positioned within a staple cartridge channel, said staple cartridge comprising:

a compressible staple cartridge body comprising a bottom surface; and

a plurality of staples embedded within said compressible staple cartridge body, wherein each said staple comprises a base and a deformable leg extending from said base, and wherein said bases of said staples are positioned below said bottom surface.

15. The staple cartridge of claim 14, wherein said staple cartridge further comprises a water impermeable layer surrounding said compressible staple cartridge body.

16. The staple cartridge of claim 14, wherein said deformable legs of said staples are embedded within said compressible staple cartridge body.
