Staple cartridge comprising compressible distortion resistant components
First Claim
1. An assembly for use with a surgical stapler, said assembly comprising:
- a cartridge channel;
a cartridge body positioned within said cartridge channel, comprising;
a support portion;
a plurality of staple cavities defined within said support portion, wherein each said staple cavity comprises an opening in said support portion;
at least one distortion minimizing member extending from at least one of said cartridge channel and said support portion; and
an implantable compressible portion, wherein said distortion minimizing member is engaged with said compressible portion, wherein said compressible portion comprises;
a first surface positioned adjacent to said support portion;
a tissue-contacting surface; and
a porous body extending between said first surface and said tissue-contacting surface, wherein said porous body is sufficiently deflectable to permit said tissue-contacting surface to move laterally relative to said first surface, wherein said at least one distortion minimizing member is configured to inhibit the lateral deflection of said porous body; and
a plurality of staples, wherein at least a portion of each said staple is removably stored within a said staple cavity, wherein each said staple is movable between an unfired position and a fired position, wherein each said staple is deformable between an unfired configuration and a fired configuration when each said staple is moved between a said unfired position and a said fired position, and wherein said compressible portion is configured to be captured within said staples and assume different compressed heights within different said staples when said staples are deformed between said unfired configuration and said fired configuration.

Abstract
A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator 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 a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.

7. A staple cartridge for use with a surgical stapler, said staple cartridge comprising:
-
a cartridge body, comprising; a support portion; a plurality of staple cavities defined within said support portion, wherein each said staple cavity comprises an opening in said support portion and a guide groove; a plurality of stiffening members extending from said support portion; and an implantable compressible portion, wherein said stiffening members are at least partially embedded in said compressible portion, wherein said compressible portion comprises; a first surface positioned adjacent to said support portion; a tissue-contacting surface; and a porous body extending between said first surface and said tissue-contacting surface, wherein said porous body is sufficiently deflectable to permit said tissue-contacting surface to move at least one of laterally and longitudinally relative to said first surface, wherein said stiffening members extend through said first surface and at least partially through said porous body, and wherein said stiffening members are configured to inhibit at least one of the lateral and the longitudinal deflection of said porous body; and a plurality of staples, wherein at least a portion of each said staple is removably stored within a said staple cavity, wherein each said staple is movable between an unfired position and a fired position, wherein each said staple is deformable between an unfired configuration and a fired configuration when each said staple is moved between a said unfired position and a said fired position, wherein each said staple comprises at least one deformable leg removably positioned in said guide groove when said staple is in said unfired position, and wherein said compressible portion is configured to be captured within said staples and assume different compressed heights within different said staples when said staples are deformed between said unfired configuration and said fired configuration. - View Dependent Claims (8, 9, 10, 11)
