Abstract: According to aspects of the present disclosure, a retrieval device may include a sheath, a first drive member in the sheath, and a second drive member in the sheath. The second drive member may be movable relative to the first drive member. An end effector may be retractable into and extendable out of the sheath. The end effector may include a first proximal end portion coupled to the first drive member, a second proximal end portion coupled to the second drive member, and a plurality of legs extending distally from the first and second proximal end portions to a distal tip of the end effector. All of the legs that extend to the distal tip may be fixed together at the distal tip.
