Abstract: A medical retrieval device of an embodiment of the present disclosure includes a proximal handle, a sheath, and a retrieval assembly. The sheath extends from the handle and includes a lumen and a distal end opposite the handle. The retrieval assembly is moveable relative to the sheath to achieve a collapsed position of the retrieval assembly within the lumen and an expanded position of the retrieval assembly when extended outside the lumen. The retrieval assembly includes a plurality of legs. At least one of the legs includes a wire having an inner core at least partially surrounded by an outer layer.

Abstract: An embodiment of a medical device includes a proximal handle, a distal end effector, an elongate member connecting the end effector to the handle, and a sheath enclosing at least a portion of the elongate member. The handle may include a first mechanism coupled to one of the sheath and the elongate member to move the sheath relative to the elongate member, a second mechanism coupled to the elongate member to rotate the elongate member relative to the handle, and a locking mechanism coupled to the first mechanism to hold the first mechanism in a default position. Embodiments also include methods of positioning the medical device to perform a medical procedure.
