The stent delivery device includes a pistol shaped handle with a barrel portion extending atop a grip portion. A trigger actuator is pivotably mounted to the pistol shaped handle and defines an angle with respect to the grip portion. A carrier is slidably mounted to the barrel portion of the pistol shaped handle. A mechanical linkage, which includes a roller clutch, interconnects the trigger actuator to the carrier. The angle is reduced responsive to pivoting the trigger actuator in an actuation direction toward the grip portion, and the angle is increased responsive to pivoting the trigger actuator in a re-set direction. The roller clutch is oriented in the mechanical linkage to rotate responsive to the trigger pivoting in the re-set direction, but the roller clutch is held against rotation responsive to pivoting the trigger in the actuation direction.
