Claim 10:
11. A retrieval device, comprising:
a handle configured to be coupled to a scope device;
a slider movable relative to the handle;
a sheath including a proximal end coupled to the slider;
a drive wire received within the sheath so that the sheath is slidable over the drive wire as the sheath is moved relative to the handle;
an end effector coupled to a distal end of the drive wire, the end effector being movable between a first configuration when the sheath is moved distally to a distal position in which the sheath covers the end effector and a second configuration when the sheath is moved proximally to a first proximal position in which at least a portion of the end effector extends distally beyond a distal end of the sheath;
an actuator including a lever coupled to the slider via an arm so that movement of the lever between a first position and a second position moves the slider between a first position and a second position by rotating the arm to move a portion of the arm coupled to the slider relative to a longitudinal slider axis; and
a trigger movable within a slot of the handle and coupled to the sheath, wherein the trigger is independently actuated to move the sheath relative to the drive wire, a range of motion of the trigger permitting motion of the sheath to a second proximal position different from the first proximal position.
