The end effector is shaped and dimensioned for supporting a cartridge housing and an anvil structure. The cartridge housing and anvil structure are relatively movable between a first spaced apart position and a second position in close approximation with one another. A firing mechanism is associated with the end effector and the 10 cartridge housing for selective actuation and wherein the end effector has a radius of curvature optimized for a male pelvis. 04/08/11,19387 speci,231/36 cm co cm 00 co cn cc cn Mo CD co C) 00 r- co cli Cli 00 C) Cj cli co
