Claim 0:
1. An apparatus for performing a medical procedure, comprising:
a shaft comprising a proximal end, a distal end sized for introduction into a patient's body, and a longitudinal axis extending between the proximal and distal ends;
first and second jaws on the distal end of the shaft, the second jaw movable by one or more hinges relative to the first jaw between open and closed positions, thereby directing first and second contact surfaces of the first and second jaws away from and towards one another, respectively;
a plurality of staples received within receptacles in the first jaw and positioned on opposite sides of a cutting element, wherein at least some of the receptacles have lengths parallel to the longitudinal axis that are different than lengths of other receptacles, and wherein the staples comprise bases between tines having base lengths corresponding to the lengths of the receptacles in which they are received; and
a handle on the proximal end of the shaft comprising:
a first actuator for directing one or both of the first and second jaws to the closed position to secure tissue between the first and second contact surfaces,
a second actuator for deploying the staples from the receptacles through the secured tissue towards the second jaw to deform the staples; and
a third actuator for advancing the cutting element from a retracted position to an advanced position aligned with the longitudinal axis to sever the stapled tissue,

wherein the receptacles are arranged in rows aligned with the longitudinal axis, the receptacles consisting of a proximal set of first receptacles immediately adjacent the one or more hinges and a distal set of second receptacles distal to the proximal-most set of receptacles, the first receptacles all having a first length along the axis that is different than a second length of the second receptacles along the axis such that, as the jaws close, staples in the proximal-most set of are deployed before staples in the second set.
