A staple cartridge assembly for use with a surgical stapler is disclosed. The staple cartridge assembly comprises a cartridge body comprising a proximal cartridge end, a distal cartridge end, a deck, and a staple cavity. The staple cavity comprises a proximal cavity end, a distal cavity end, a proximal guide extending above and below the deck, a distal guide extending above and below the deck, and a connecting slot extending between the proximal cavity end and the distal cavity end. The proximal guide and the distal guide extend laterally with respect to the connecting slot. The staple cartridge assembly further comprises a staple removably stored in the staple cavity. The staple comprises a proximal leg positioned within the proximal guide, a distal leg positioned within the distal guide, and a base extending between the proximal leg and the distal leg. The base is positioned in the connecting slot.
1. A staple cartridge assembly for use with a surgical stapler, wherein said staple cartridge assembly comprises: a cartridge body, comprising: a proximal cartridge end;a distal cartridge end;a deck;a longitudinal knife slot defined in said deck extending from said proximal cartridge end toward said
1. A staple cartridge assembly for use with a surgical stapler, wherein said staple cartridge assembly comprises: a cartridge body, comprising: a proximal cartridge end;a distal cartridge end;a deck;a longitudinal knife slot defined in said deck extending from said proximal cartridge end toward said distal cartridge end; anda staple cavity, comprising: a top opening defined in said deck;a proximal cavity end;a distal cavity end;a proximal guide;a distal guide, wherein said proximal guide and said distal guide extend above said deck; anda cavity slot extending between said proximal cavity end and said distal cavity end, wherein said proximal guide and said distal guide extend laterally with respect to said cavity slot; anda staple removably stored in said staple cavity, comprising: a proximal leg positioned within said proximal guide;a distal leg positioned within said distal guide; anda base extending between said proximal leg and said distal leg, wherein said base is positioned in said cavity slot. 2. The staple cartridge assembly of claim 1, wherein said proximal guide and said distal guide extend toward said knife slot. 3. The staple cartridge assembly of claim 1, wherein said proximal guide and said distal guide extend away from said knife slot. 4. The staple cartridge assembly of claim 1, wherein said proximal guide comprises a proximal bracket. 5. The staple cartridge assembly of claim 4, wherein said proximal bracket does not extend around said proximal cavity end. 6. The staple cartridge assembly of claim 4, wherein said cavity slot is defined by a longitudinal axis, and wherein said proximal bracket is not aligned with said longitudinal axis. 7. The staple cartridge assembly of claim 1, wherein said distal guide comprises a distal bracket. 8. The staple cartridge assembly of claim 7, wherein said distal bracket does not extend around said distal cavity end. 9. The staple cartridge assembly of claim 7, wherein said cavity slot is defined by a longitudinal axis, and wherein said distal bracket is not aligned with said longitudinal axis. 10. The staple cartridge assembly of claim 1, wherein said proximal leg and said distal leg define a staple leg plane, wherein said base comprises a drive surface in a drive plane offset from said staple leg plane, wherein said proximal guide and said distal guide are aligned with said staple leg plane, and wherein said proximal guide and said distal guide are not aligned with said drive plane. 11. The staple cartridge assembly of claim 1, wherein said proximal leg and said distal leg define a staple leg plane, wherein said base comprises a drive surface in a drive plane offset from said staple leg plane, and wherein said proximal guide and said distal guide define a bracket plane aligned with said staple leg plane. 12. The staple cartridge assembly of claim 1, wherein said cartridge body further comprises a plurality of said staple cavities, and wherein said staple cartridge assembly further comprises a plurality of said staples positioned in said staple cavities. 13. The staple cartridge assembly of claim 1, wherein a portion of said proximal guide that extends above said deck comprises a staple cavity extender, and wherein a portion of said distal guide that extends above said deck comprises a staple cavity extender. 14. A staple cartridge assembly for use with a surgical stapler, wherein said staple cartridge assembly comprises: a cartridge body, comprising: a proximal cartridge end;a distal cartridge end;a deck; anda staple cavity, comprising: a proximal cavity end;a distal cavity end;a proximal guide extending above and below said deck;a distal guide extending above and below said deck; anda connecting slot extending between said proximal cavity end and said distal cavity end, wherein said proximal guide and said distal guide extend laterally with respect to said connecting slot; anda staple removably stored in said staple cavity, comprising: a proximal leg positioned within said proximal guide;a distal leg positioned within said distal guide; anda base extending between said proximal leg and said distal leg, wherein said base is positioned in said connecting slot. 15. The staple cartridge assembly of claim 14, wherein said cartridge body further comprises a plurality of said staple cavities, and wherein said staple cartridge assembly further comprises a plurality of said staples positioned in said staple cavities. 16. The staple cartridge assembly of claim 14, wherein a portion of said proximal guide that extends above said deck comprises a staple cavity extender, and wherein a portion of said distal guide that extends above said deck comprises a staple cavity extender. 17. A fastener cartridge assembly for use with a surgical fastening instrument, wherein said fastener cartridge assembly comprises: a cartridge body, comprising: a proximal cartridge end;a distal cartridge end;a deck; anda fastener pocket, comprising: a proximal pocket end;a distal pocket end;a proximal guide;a distal guide;a proximal pocket extender, wherein said proximal pocket extender extends above said deck;a distal pocket extender, wherein said distal pocket extender extends above said deck; anda pocket opening extending between said proximal pocket end and said distal pocket end, wherein said proximal guide and said distal guide extend laterally with respect to said pocket opening; anda fastener removably stored in said fastener pocket, comprising: a proximal leg positioned within said proximal guide;a distal leg positioned within said distal guide; anda base extending between said proximal leg and said distal leg, wherein said base is positioned in said pocket opening. 18.
