An end effector can comprise, one, a fastener cartridge including a plurality of fasteners stored therein and, two, an anvil configured to deform the fasteners. The anvil can further comprise extensions extending therefrom which can control the flow of tissue relative to the fastener cartridge and/or support the fasteners as they are ejected from the fastener cartridge. The extensions can having different sizes and/or configurations.
1. A fastener cartridge, comprising: a cartridge body including a deck configured to support tissue;a fastener cavity defined in said cartridge body, wherein said fastener cavity comprises a first cavity end and a second cavity end, wherein said first cavity end comprises a first lateral sidewall an
1. A fastener cartridge, comprising: a cartridge body including a deck configured to support tissue;a fastener cavity defined in said cartridge body, wherein said fastener cavity comprises a first cavity end and a second cavity end, wherein said first cavity end comprises a first lateral sidewall and a second lateral sidewall, wherein said first lateral sidewall and said second lateral sidewall converge; anda fastener removably stored in said fastener cavity, comprising: a base;a first leg extending from said base, wherein said first leg is removably positioned in said first cavity end, wherein said first lateral sidewall and said second lateral sidewall contact said first leg and hold said first leg away from said sidewall convergence such that a gap is present between said sidewall convergence and said first leg; anda second leg extending from said base, wherein said second leg is removably positioned in said second cavity end. 2. The fastener cartridge of claim 1, wherein said second cavity end comprises a first lateral sidewall and a second lateral sidewall, and wherein said first lateral sidewall and said second lateral sidewall of said second cavity end contact said second leg and hold said second leg away from a second sidewall convergence such that a gap is present between said second sidewall convergence and said second leg. 3. The fastener cartridge of claim 2, further comprising a pocket extender extending from said deck, wherein said pocket extender is configured to support said first leg as said fastener is ejected from said fastener cavity. 4. The fastener cartridge of claim 3, further comprising a second pocket extender extending from said deck, wherein said second pocket extender is configured to support said second leg as said fastener is ejected from said fastener cavity. 5. A fastener cartridge, comprising: a cartridge body including a deck configured to support tissue;a fastener cavity defined in said cartridge body, wherein said fastener cavity comprises a first cavity end, a second cavity end, and a wedge; anda fastener removably stored in said fastener cavity, comprising: a base;a first leg extending from said base, wherein said first leg is removably positioned relative to said first cavity end, wherein said wedge contacts said first leg and holds said first leg away from said first cavity end such that a gap is present between said first cavity end and said first leg; anda second leg extending from said base, wherein said second leg is removably positioned relative to said second cavity end. 6. The fastener cartridge of claim 5, further comprising a second wedge, wherein said second wedge contacts said second leg and holds said second leg away from said second cavity end such that a gap is present between said second cavity end and said second leg. 7. The fastener cartridge of claim 6, further comprising a pocket extender extending from said deck, wherein said pocket extender is configured to support said first leg as said fastener is ejected from said fastener cavity. 8. The fastener cartridge of claim 7, further comprising a second pocket extender extending from said deck, wherein said second pocket extender is configured to support said second leg as said fastener is ejected from said fastener cavity. 9. A fastener cartridge, comprising: a cartridge body including a deck configured to support tissue;a fastener cavity defined in said cartridge body, wherein said fastener cavity comprises a longitudinal slot including a first cavity end and a second cavity end; anda fastener removably stored in said fastener cavity, comprising: a base;a first leg extending from said base; anda second leg extending from said base, wherein said fastener cavity further comprises:first biasing means for biasing said first leg away from said first cavity end; andsecond biasing means for biasing said second leg away from said second cavity end, wherein said first biasing means contacts said first leg, wherein said second biasing means contacts said second leg, and wherein said fastener is configured to move relative to said first biasing means and said second biasing means.
