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.

Abstract: According to one aspect, a medical device may include a luminal element configured for insertion into a natural body lumen. The medical device may further include a tool configured to be received within the luminal element. The tool may include a plurality of operating members. Each of the operating members may include an elongate member and a cutting member. The cutting member may be located at a distal end of the elongate member. Further, the cutting member of a first operating member of the plurality of operating members may be rotatable with respect to the cutting member of a second operating member of the plurality of operating members.
