1. A surgical stapling system, comprising:
- a shaft comprising a proximal end and a distal end;
an end effector extending from said distal end of said shaft, wherein said end effector is movable between an open configuration and a closed configuration, and wherein said end effector comprises;
a frame; and
an anvil extending distally from said frame, wherein said anvil comprises a longitudinal row of forming pockets;
a first staple cartridge assembly attachable to said end effector, comprising;
a first cartridge body comprising a first longitudinal row of staple cavities; and
a plurality of first staples removably stored in said first longitudinal row of staple cavities, wherein each said first staple is comprised of a bent wire, and wherein each said first staple is aligned with a said forming pocket when said end effector is in said closed configuration; and
a second staple cartridge assembly attachable to said end effector in lieu of said first staple cartridge assembly, wherein said second staple cartridge assembly, comprises;
a second cartridge body comprising a second longitudinal row of staple cavities; and
a plurality of second staples removably stored in said second longitudinal row of staple cavities, wherein each said second staple is formed from flat stock, and wherein each said second staple is aligned with a said forming pocket when said end effector is in said closed configuration.
