25. An end effector for fastening tissue, comprising:
-
a proximal end; a distal end; a first jaw comprising a cartridge, wherein said cartridge comprises a deck and a plurality of staple cavities, wherein said plurality of staple cavities are arranged in a first longitudinal row of staple cavities and a second longitudinal row of staple cavities, wherein said deck is configured to support tissue, and wherein said deck comprises; a first deck surface, wherein said first longitudinal row of staple cavities is defined in said first deck surface; a second deck surface, wherein said second longitudinal row of staple cavities is defined in said second deck surface; and a wall defined between said first deck surface and said second deck surface; a plurality of first staples removably stored within said first longitudinal row of staple cavities; a plurality of second staples removably stored within said second longitudinal row of staple cavities; a second jaw comprising an anvil configured to deform said first staples to a first deformed height and said second staples to a second deformed height, wherein said first deformed height is different than said second deformed height; a plurality of staple drivers, wherein said staple drivers are configured to lift said first staples and said second staples toward said anvil; and a firing member movable toward said distal end, wherein said firing member is configured to lift said staple drivers toward said anvil, wherein said firing member comprises a first portion configured to engage said first jaw and a second portion configured to engage said second jaw, and wherein said firing member is configured to relatively position said anvil and said cartridge. - View Dependent Claims (26, 27, 28, 29, 30, 31)
