Abstract: A retrieval device may have a contracted state and an expanded state and may include a sheath defining a longitudinal axis; a first arm, a second arm, and a third arm; a first member extending between a distal end of the first arm and a distal end of the third arm; and a second member extending between a distal end of the second arm and the distal end of the third arm. In the expanded state and from a distal-end view, the first and second members and the distal ends of the first arm, second arm, and third arm may form a V-shape with an open mouth.
