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 comprised of different materials which can apply pressure to the tissue. These different materials can have different stiffnesses and/or spring rates.

Claims

1. A staple cartridge, comprising:

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

an implantable staple cartridge body, comprising;

a first compressible layer comprised of a first material, wherein said bases are embedded in said first compressible layer;

a second compressible layer comprised of a second material, wherein said tips are embedded in said second compressible layer, wherein said first compressible layer comprises a first stiffness, wherein said second compressible layer comprises a second stiffness, and wherein said first stiffness is different than said second stiffness; and

a wrap surrounding said first compressible layer and said second compressible layer, wherein said tips are configured to incise said wrap when said implantable staple cartridge body is compressed by an anvil.

2. A staple cartridge, comprising:

a plurality of undeformed staples; and

an implantable staple cartridge body comprising a plurality of layers, wherein said plurality of layers forms a unitary implantable piece, and wherein said plurality of layers comprises;

a first compressible layer comprised of a first material, wherein said undeformed staples are embedded in said first compressible layer; and

a second compressible layer comprised of a second material, wherein said first compressible layer comprises a first stiffness, wherein said second compressible layer comprises a second stiffness, and wherein said first stiffness is different than said second stiffness;

wherein said plurality of staples are arranged in a first inner staple row, a first outer staple row, a second inner staple row, and a second outer staple row, wherein said first compressible layer is thicker along said first inner staple row and said second inner staple row than said first outer staple row and said second outer staple row.

3. A fastener cartridge, comprising:

a plurality of fasteners, wherein each said fastener comprises a base and a deformable member extending from said base, wherein each said deformable member comprises a tip; and
