A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.
1. A surgical end effector, comprising: an anvil;a staple cartridge, comprising: a cartridge body comprising a deck;a plurality of staple cavities defined in said cartridge body;a plurality of staples removably positioned in said staple cavities; anda plurality of drivers movably positioned in said
1. A surgical end effector, comprising: an anvil;a staple cartridge, comprising: a cartridge body comprising a deck;a plurality of staple cavities defined in said cartridge body;a plurality of staples removably positioned in said staple cavities; anda plurality of drivers movably positioned in said staple cavities, wherein each said driver is movable from an unfired position to a fully fired position, and wherein said plurality of drivers comprises: a proximal driver comprising a first surface, wherein said first surface is positioned above said deck when said proximal driver is moved to its fully fired position; anda distal driver comprising a second surface, wherein said second surface is positioned above said deck when said distal driver is moved to its fully fired position, and wherein said second surface is positioned above said first surface when said proximal driver and said distal driver are in their fully fired positions; anda firing element configured to move said drivers from their unfired positions to their fully fired positions during a firing stroke; anda layer positioned adjacent to said deck, wherein said layer is configured to be progressively released from said deck during the firing stroke. 2. The surgical end effector of claim 1, wherein said proximal driver and said distal driver are connected. 3. The surgical end effector of claim 1, wherein said layer comprises a tissue thickness compensator. 4. The surgical end effector of claim 1, wherein said layer comprises a buttress. 5. The surgical end effector of claim 1, further comprising a second layer positioned adjacent to said anvil. 6. The surgical end effector of claim 5, wherein said second layer comprises a tissue thickness compensator. 7. The surgical end effector of claim 5, wherein said second layer comprises a buttress. 8. The surgical end effector of claim 1, wherein said deck comprises a stepped deck. 9. A surgical end effector, comprising: an anvil;a staple cartridge, comprising: a cartridge body comprising a deck;a plurality of staple cavities defined in said cartridge body;a plurality of staples removably positioned in said staple cavities; anda plurality of drivers movably positioned in said staple cavities, wherein each said driver is movable from an unfired position to a fully fired position, and wherein said plurality of drivers comprises: a proximal driver comprising a first surface, wherein said first surface is positioned above said deck when said proximal driver is moved to its fully fired position; anda distal driver comprising a second surface, wherein said second surface is positioned above said deck when said distal driver is moved to its fully fired position, and wherein said second surface is positioned closer to said anvil than said first surface when said proximal driver and said distal driver are in their fully fired positions; anda firing element configured to move said drivers from their unfired positions to their fully fired positions during a firing stroke; anda layer positioned adjacent to said deck, wherein said layer is configured to be progressively released from said deck during the firing stroke. 10. The surgical end effector of claim 9, wherein said proximal driver and said distal driver are connected. 11. The surgical end effector of claim 9, wherein said layer comprises a tissue thickness compensator. 12. The surgical end effector of claim 9, wherein said layer comprises a buttress. 13. The surgical end effector of claim 9, further comprising a second layer positioned adjacent to said anvil. 14. The surgical end effector of claim 13, wherein said second layer comprises a tissue thickness compensator. 15. The surgical end effector of claim 13, wherein said second layer comprises a buttress. 16. The surgical end effector of claim 9, wherein said deck comprises a stepped deck. 17. A staple cartridge assembly, comprising: a cartridge body comprising a deck;a plurality of staple cavities defined in said cartridge body;a plurality of staples removably positioned in said staple cavities;a plurality of drivers movably positioned in said staple cavities, wherein each said driver is movable from an unfired position to a fully fired position during a firing stroke, and wherein said plurality of drivers comprises: a proximal driver comprising a first surface, wherein said first surface is positioned above said deck when said proximal driver is moved to its fully fired position; anda distal driver comprising a second surface, wherein said second surface is positioned above said deck when said distal driver is moved to its fully fired position, and wherein said second surface is positioned above said first surface when said proximal driver and said distal driver are in their fully fired positions; anda layer positioned adjacent to said deck, wherein said layer is configured to be progressively released from said deck during the firing stroke. 18. The staple cartridge assembly of claim 17, wherein said proximal driver and said distal driver are connected. 19. The staple cartridge assembly of claim 17, wherein said layer comprises a tissue thickness compensator. 20. The staple cartridge assembly of claim 17, wherein said deck comprises a stepped deck.
