Medical handle

A retrieval device comprising:

• a handle comprising:
• a slider movable in a proximal direction and a distal direction;
• and
• a lever coupled to the slider;
• a sheath coupled to the slider;
• a drive wire including an end effector at a distal end of the drive wire, wherein the drive wire and the end effector are received within the sheath, and wherein the sheath is movable relative to the drive wire and the end effector;
• and
• a guide member configured to couple the handle to a scope device, wherein the lever is configured to rotate about the guide member to thereby move the slider in the proximal direction and the distal direction.
