Claim 16:
17. A retrieval device, comprising:
a handle configured to be coupled to a scope device, the handle including a slider assembly;
a sheath including a proximal end coupled to the slider assembly;
a drive wire received within the sheath so that the sheath is slidable over the drive wire, a distal end of the drive wire including an expandable end effector movable between a collapsed configuration when the sheath is moved distally to a distal position in which the sheath covers the end effector and an expanded 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 assembly coupled to the handle and the slider assembly, the actuator assembly being movable relative to the handle to move the sheath between the distal and the first proximal positions via the slider assembly;
a trigger movably coupled to the handle and coupled to the sheath, the trigger being configured to permit movement of the sheath to a second proximal position different from the first proximal position; and
a guide member configured to couple the handle to the scope device, the handle being movable relative to the guide member.
