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.
1. A staple cartridge, comprising: a cartridge body comprising a laterally sloped deck and staple cavities;staples at least partially positioned within said staple cavities;a layer attached to said deck, wherein said layer at least partially extends over said staple cavities, and wherein said layer
1. A staple cartridge, comprising: a cartridge body comprising a laterally sloped deck and staple cavities;staples at least partially positioned within said staple cavities;a layer attached to said deck, wherein said layer at least partially extends over said staple cavities, and wherein said layer is positioned adjacent to said laterally sloped deck;a clamping mechanism configured to releasably secure said layer to said cartridge body, said clamping mechanism comprising: a clamp portion; anda retention portion moveable between an engaged configuration wherein said retention portion is engaged with said layer and positioned above said deck and a disengaged configuration wherein said retention portion is disengaged from said layer and positioned lower than said deck; anda firing assembly movable through said cartridge body to eject said staples from said staple cavities during a firing stroke of said firing assembly, wherein said firing assembly is configured to engage said retention portion to transition said retention portion into said disengaged configuration during said firing stroke. 2. The staple cartridge of claim 1, wherein said firing stroke comprises an end position, wherein said firing assembly is configured to eject all of said staples from said staple cavities before reaching said end position, and wherein said firing assembly is configured to release said layer before reaching said end position. 3. The staple cartridge of claim 1, wherein said firing stroke comprises an end position, wherein said firing assembly is configured to eject all of said staples from said staple cavities before reaching said end position, and wherein said firing assembly is configured to release said layer upon reaching said end position. 4. The staple cartridge of claim 1, wherein said staples comprise different unformed heights, and wherein said staples comprise different formed heights. 5. The staple cartridge of claim 1, wherein said layer comprises a tissue thickness compensator. 6. A staple cartridge, comprising: a cartridge body comprising a laterally sloped deck and staple cavities;staples at least partially positioned within said staple cavities;a layer attached to said deck, wherein said layer at least partially extends over said staple cavities, and wherein said layer is positioned adjacent said laterally sloped deck;a retention pin engaged with said layer to secure said layer to said cartridge body, wherein said retention pin is moveable between a first configuration wherein said retention pin is engaged with said layer and positioned above said deck and a second configuration wherein said retention pin is separated from said layer and positioned below said deck; anda firing member movable through said cartridge body to eject said staples from said staple cavities during a firing stroke of said firing member, wherein said firing member is configured to engage said retention pin to transition said retention pin into said second configuration during said firing stroke to release said layer from said cartridge body. 7. The staple cartridge of claim 6, wherein said firing stroke comprises an end position, wherein said firing member is configured to eject all of said staples from said staple cavities before reaching said end position, and wherein said firing member is configured to release said layer before reaching said end position. 8. The staple cartridge of claim 6, wherein said firing stroke comprises an end position, wherein said firing member is configured to eject all of said staples from said cartridge body before reaching said end position, and wherein said firing member is configured to release said layer upon reaching said end position. 9. The staple cartridge of claim 6, wherein said staples comprise different unformed heights, and wherein said staples comprise different formed heights. 10. The staple cartridge of claim 6, wherein said layer comprises a tissue thickness compensator. 11. The staple cartridge of claim 6, further comprising a biasing member configured to bias said retention pin into engagement with said layer, and wherein said firing member is configured to overcome said biasing member during said firing stroke. 12. An end effector of a surgical instrument, said end effector comprising: an anvil; anda staple cartridge, comprising: a cartridge body comprising a laterally stepped deck and staple cavities;staples at least partially positioned within said staple cavities;a layer attached to said deck, wherein said layer at least partially extends over said staple cavities;an anchor configured to releasably secure said layer to said cartridge body, said anchor comprising: a clamp portion; anda retention portion moveable between an engaged configuration wherein said retention portion is engaged with said layer and positioned above said deck and a disengaged configuration wherein said retention portion is disengaged from said layer and positioned lower than said deck; anda firing member movable through said cartridge body to eject said staples from said staple cavities during a firing stroke of said firing member, wherein said anchor is engageable by said firing member during said firing stroke to release said layer such that said firing member is configured to transition said retention portion into said disengaged configuration during said firing stroke. 13. The end effector of claim 12, wherein said staple cartridge is movable relative to said anvil to capture tissue therebetween. 14. The end effector of claim 13, wherein said staples comprise different unformed heights, and wherein said staples comprise different formed heights.
