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, the cartridge body can comprise a plurality of layers wherein at least one of the layers can be detached from the other layers and removed from the surgical site.

Claims

1. A fastener cartridge, comprising:

a plurality of fasteners, wherein each said fastener comprises a base and a deformable leg;

a first layer, wherein said deformable legs are at least partially positioned within said first layer;

a second layer attached to said first layer; and

a third layer removably attached to said second layer, wherein said fastener bases are at least partially positioned within said third layer, wherein said first layer is comprised of a compressible material having a first density, and wherein said third layer is comprised of another compressible material having a density which is greater than said first density.

2. A fastener cartridge, comprising:

a plurality of fasteners, wherein each said fastener comprises a base and a tissue-capturing portion;

a first laminate comprised of a compressible material, wherein said tissue-capturing portions are at least partially positioned within said first laminate;

a second laminate attached to said first laminate; and

a third laminate removably attached to said second laminate, wherein said fastener bases are at least partially positioned within said third laminate, and wherein said third laminate comprises at least one perforation configured to permit said third laminate to be removed from said second laminate in two or more pieces.

3. A fastener cartridge, comprising:

a plurality of fasteners, wherein each said fastener comprises a base and a tissue-capturing portion;

a first laminate comprised of a compressible material, wherein said tissue-capturing portions are positioned within said first laminate;

a second laminate attached to said first laminate; and

a third laminate removably attached to said second laminate, wherein said fastener bases are at least partially positioned within said third laminate, and wherein said third laminate is comprised of a hemostatic material.

4. A staple cartridge, comprising:

a plurality of staples, wherein each said staple comprises a base and a deformable leg extending from said base;

a first layer comprised of a collapsible material, wherein said deformable legs are positioned within said first layer;

a second layer adhered to said first layer; and

a third layer detachably adhered to said second layer, wherein said third layer comprises a plurality of staple slots, wherein said staple bases are positioned within said staple slots, and wherein said first layer is comprised of a first foam material having a first density, and wherein said third layer is comprised of another foam material having a density which is greater than said first density.

5. The staple cartridge of claim 4, wherein said third layer comprises at least one perforation configured to permit said third layer to be removed from said second layer in two or more pieces.

6. The staple cartridge of claim 5, wherein said plurality of staples are arranged in a first staple row and a second staple row, and wherein said at least one perforation extends between said first staple row and said second staple row.

7. The staple cartridge of claim 6, wherein said staple slots are configured to provide clearance between said staple bases and said third layer.

8. A staple cartridge, comprising:

a plurality of staples, wherein each said staple comprises a base and a deformable leg extending from said base;

a first layer comprised of a collapsible material, wherein said deformable legs are positioned within said first layer;

a second layer adhered to said first layer; and
