Abstract

A surgical stapling assembly is disclosed. The assembly can include a cartridge body having cavities defined therein forming a pattern of openings in the deck of the cartridge body. The pattern can include longitudinally-repeating clusters of cavity ends. The assembly can also include fasteners removably positioned in the cavities. The pattern of openings can comprise openings on a first side of the cartridge body comprising inner openings each defining an inner proximal-to-distal axis oriented parallel to the longitudinal axis, outer openings each defining an outer proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an outer angle, and intermediate openings each defining an intermediate proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an intermediate angle, wherein the intermediate angle is different than the outer angle. The assembly can include a sled having offset ramps and/or an anvil comprising an arrangement of forming pockets proximal to the tissue stop.
