1. A surgical stapling system for stapling patient tissue, comprising:

  • a handle;

    a shaft extending from said handle;

    an end effector attachable to said shaft, wherein said end effector comprises;

    an anvil;

    a staple cartridge, comprising;

    a cartridge body comprising a deck surface including a plurality of staple cavities, wherein said deck surface comprises a first longitudinal deck surface and a second longitudinal deck surface, and wherein said first longitudinal deck surface is taller than said second longitudinal deck surface;

    a plurality of staples removably positioned in said staple cavities, wherein said plurality of staples comprises a first longitudinal row of staples having a first unformed height and a second longitudinal row of staples having a second unformed height, and wherein said first unformed height is different than said second unformed height;

    a longitudinal slot defined in said cartridge body;

    a proximal end; and

    a distal end;

    an implantable layer positioned adjacent to said deck surface; and

    a plurality of anchors configured to releasably retain said implantable layer to said cartridge body, wherein said plurality of anchors extend over said first longitudinal deck surface and said second longitudinal deck surface; and

    a firing system comprising a tissue cutting edge, wherein said firing system is configured to translate within said longitudinal slot from said proximal end toward said distal end such that said anchors are progressively transected by said tissue cutting edge to progressively release said implantable layer from said cartridge body while said staples are progressively ejected from said staple cavities to staple the patient tissue.
