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;

a plurality of staple supports, wherein each said staple support comprises a trough;

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

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

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

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

a plurality of staples partially embedded within said compressible and implantable staple cartridge body, wherein each said staple is positioned above a said staple support and aligned with a said trough.

2. The surgical stapling system of claim 1, wherein said compressible and implantable 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 and implantable staple cartridge body.

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

5. A surgical stapling system, comprising:

a staple cartridge attachment portion comprising a plurality of staple supports, wherein each said staple support comprises a groove;

a staple cartridge removably positioned within said staple cartridge attachment portion, said staple cartridge comprising;

a compressible and implantable staple cartridge body; and

a plurality of staples partially embedded within said compressible and implantable staple cartridge body, wherein each said staple comprises a base and a deformable leg extending from said base, and wherein each said staple is positioned above a said staple support and aligned with a said groove; 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 and implantable staple cartridge body when said anvil is in said intermediate position.

6. The surgical stapling system of claim 5, wherein said compressible and implantable staple cartridge body comprises a bottom surface, and wherein said bases of said staples are positioned below said bottom surface.

7. The surgical stapling system of claim 6, wherein said staple cartridge further comprises a water impermeable layer surrounding said compressible and implantable staple cartridge body.

8. The surgical stapling system of claim 7, wherein said layer extends between said staple bases and said staple supports.

9. The surgical stapling system of claim 5, wherein said staple cartridge attachment portion comprises a lateral cartridge support surface configured to inhibit movement of said staple cartridge relative to a bottom support surface of said staple cartridge attachment portion.

10. The surgical stapling system of claim 5, wherein said anvil is configured to engage said staple legs when said anvil is in said intermediate position.

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

a compressible and implantable staple cartridge body comprising a bottom surface;

non-implantable portions comprising a plurality of grooves; and

a plurality of undeformed staples partially embedded within said compressible and implantable staple cartridge body, wherein each said undeformed staple comprises a base and a deformable leg extending from said base, and wherein said bases of said undeformed staples are positioned below said bottom surface in said grooves of said non-implantable portions.

12. The staple cartridge of claim 11, wherein said staple cartridge further comprises a water impermeable layer surrounding said compressible and implantable staple cartridge body.

13. The staple cartridge of claim 11, wherein said deformable legs of said undeformed staples are embedded within said compressible and implantable staple cartridge body.

14. A surgical stapling system, comprising:

a compressible and implantable staple cartridge body comprising a bottom surface;

a plurality of staple supports, wherein each said staple support comprises a groove;

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