1. A retrieval device, comprising:
a handle configured to be coupled to a scope device, the handle further 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;
an expandable end effector coupled to a distal end of the drive wire, the 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 slider assembly within the handle to move the sheath over the drive wire between the distal and first proximal positions;
a trigger movably coupled to the handle and coupled to the sheath, the trigger being configured to move the sheath to a second proximal position different from the first proximal position independent of the actuator assembly; and
a guide member configured to couple the handle to the scope device, the handle being movable relative to the guide member.
