1-17. (canceled)
A staple cartridge, comprising:
- a cartridge body, comprising:
- a proximal end;
- a distal end;
- a knife slot extending through said cartridge body from said proximal end to said distal end;
- and
- staple cavities defined in said cartridge body, wherein said staple cavities are arranged in an inner longitudinal row of staple cavities, a middle longitudinal row of staple cavities, and an outer longitudinal row of staple cavities on one side of said knife slot;
- staples removably stored within said staple cavities;
- a proximal staple driver configured to eject a first quantity of staples from said staple cavities during a firing motion;
- an intermediate staple driver positioned distally with respect to said proximal staple driver, wherein said intermediate staple driver is configured to eject a second quantity of staples from said staple cavities which is different than said first quantity during the firing motion, and wherein said second quantity of staples includes a staple from said inner longitudinal row of staple cavities and a staple from said outer longitudinal row of staple cavities;
- and
- a distal staple driver positioned distally with respect to said intermediate staple driver and configured to eject a third quantity of staples during the firing motion, wherein said third quantity of staples is the same as said first quantity of staples.
