Abstract:

A fastener cartridge can comprise, one, a cartridge body configured to at least partially store a plurality of fasteners therein and, two, a layer of material attached to the cartridge body by a retention member. The retention member can be deactivated to release the layer from the cartridge body when a firing member is moved through the cartridge body to eject the fasteners from the cartridge body. The retention member can be deactivated at the beginning, the end, and/or at any suitable time during a firing stroke of the firing member. Certain fastener cartridges can comprise a plurality of retention members configured to releasably hold the layer to the cartridge body. In certain circumstances, the retention members can be sequentially released in order to progressively release the layer.
