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.
