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 that are movable relative to one another 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;
first and second sets of staples carried by the first jaw and positioned in rows parallel to the longitudinal axis, wherein at least some of the staples are a different size than other staples; 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 first jaw through the secured tissue towards the second jaw to deform the staples; and
an imaging assembly carried on the shaft comprising:
an elongate tubular member mounted over the shaft comprising a proximal portion positioned adjacent the handle, and a distal portion positioned adjacent the first and second jaws;
a pair of deployment arms on the distal portion, each deployment arm comprising a first end pivotably coupled to the tubular member and a second free end that is movable from a retracted position wherein the second end is aligned against or within a wall of the tubular member to allow the distal portion to be introduced into the patient's body when the distal end of the shaft is introduced into the patient's body to a deployed position wherein the second end moves outwardly relative to the longitudinal axis; and
an imaging element on the second end of each deployment arm proximal to the first and second jaws to provide images from within the patient's body,
wherein the tubular member is movable axially relative to the shaft to adjust a field of view of the imaging element on each deployment arm.
