1. A stapling assembly, comprising:

  • a staple cartridge, comprising;

    a proximal end;

    a distal end;

    a deck configured to support the tissue of a patient, wherein said deck comprises a first longitudinal step and a second longitudinal step, wherein said first longitudinal step is defined by a first step height, and wherein said second longitudinal step is defined by a second step height which is different than said first step height;

    a first longitudinal row of staple cavities defined in said first longitudinal step;

    a second longitudinal row of staple cavities defined in said second longitudinal step;

    a plurality of first staples removably stored in said first longitudinal row of staple cavities;

    a plurality of second staples removably stored in said second longitudinal row of staple cavities;

    a first longitudinal row of staple drivers aligned with said first longitudinal row of staple cavities, wherein said first longitudinal row of staple drivers support said first staples at a first unfired height; and

    a second longitudinal row of staple drivers aligned with said second longitudinal row of staple cavities, wherein said second longitudinal row of staple drivers support said second staples at a second unfired height which is different than said first unfired height; and

    an anvil configured to deform said first staples to a first deformed height and said second staples to a second deformed height which is different than said first deformed height,wherein a distal compressive pressure is applied to the tissue between said anvil and said distal end of said staple cartridge, wherein a proximal compressive pressure is applied to the tissue between said anvil and said proximal end of said staple cartridge, and wherein said proximal compressive pressure is different than said distal compressive pressure, andwherein a first compressive pressure is applied to the tissue between said anvil and said first longitudinal step, wherein a second compressive pressure is applied to the tissue between said anvil and said second longitudinal step, and wherein said second compressive pressure is different than said first compressive pressure.
