Abstract

An assembly for fastening tissue is disclosed. The assembly may comprise a first jaw comprising a cartridge, wherein the cartridge comprises a plurality of fasteners. The plurality of fasteners comprises a first fastener comprising a first height and a second fastener comprising a second height, wherein the second height is different than the first height. The assembly further comprises a second jaw, wherein at least one of the first jaw and the second jaw is movable relative to the other. The second jaw comprises a plurality of fastener-engaging portions. The plurality of fastener-engaging portions comprises a first fastener-engaging portion and a second fastener-engaging portion. The assembly further comprises a compressible layer intermediate the first jaw and the second jaw.
