Claim 20:
21. An end effector for a stapler apparatus including a shaft comprising a proximal end including a handle, a distal end sized for introduction into a patient's body, and a longitudinal axis extending between the proximal and distal ends, the end effector comprising:
one or more connectors for removably connecting the end effector to the distal end of the shaft;
first and second jaws, the second jaw movable by one or more hinges relative to the first jaw between open and closed positions using a first actuator on the handle, thereby directing first and second contact surfaces of the first and second jaws away from and towards one another, respectively; and
a cartridge carried by the first jaw comprising a plurality of staples received within receptacles arranged in rows on opposite sides of a cutting element such that actuation of a second actuator on the handle deploys the staples into tissue between the first and second contact surfaces and drives the staples against the second jaw to deform the one or more staples, 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,
wherein the receptacles are arranged in rows aligned with the longitudinal axis, the receptacles comprising a proximal-most set of receptacles immediately adjacent the one or more hinges and a second set of receptacles distal to the proximal-most set of receptacles, the proximal-most set of receptacles all having a first length along the axis that is longer than a second length of the second set of 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,
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.
