Abstract: A medical device may include an elongate member, and a plurality of grasping members extending from the elongate member. Each of the grasping members may include a proximal end, and a distal end. Each of the grasping members may include at least one first section formed of a first material and a second material, and a second section located at the distal end of the grasping member. The second section may be formed without the first material and being less stiff than the at least one first section.

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: A retrieval device having a contracted state and an expanded state may include a sheath, and at least three support members each having at least two lumens, a proximal end fixed to the sheath, and a distal end movable relative to the sheath. The retrieval device may also include at least three movable members movable relative to the support members. Each movable member may extend through a lumen of one support member of the at least three support members and through a lumen of a different support member of the at least three support members.
