Abstract: A stapling assembly comprising a cartridge body, staple drivers, staples, and a sled assembly is disclosed. The cartridge body comprises a deck, a longitudinal slot, and staple cavities defined in the deck. The sled assembly is configurable in a first configuration and a second configuration. The sled assembly is movable distally in the first configuration during a staple firing stroke. The sled assembly is movable proximally in the second configuration during a retraction stroke. The sled assembly comprises a first component and a second component. The first component comprises a base and at least one rail extending from the base. The rail comprises a distal-facing ramp configured to engage the staple drivers to eject the staples from the staple cavities during the staple firing stroke. The rail is comprised of metal. The second component is movable within the longitudinal slot. The first component is movable relative to the second component.

Abstract: A method of assembling a staple cartridge is disclosed. In various embodiments, the method comprises attaching a pan to a cartridge body, the cartridge body comprising a proximal end, a distal end, a deck, longitudinal rows of staple cavities extending between the proximal end and the distal end, and a longitudinal slot extending from the proximal end toward the distal end. The method further comprises positioning staples in the staple cavities, positioning a support in the longitudinal slot such that an end of the support extends above the deck, and positioning a sled in the cartridge body proximal to the support such that the sled is longitudinally aligned with the support.
