Abstract: A medical device may include an introducer sheath, having a distal and a proximal end and a lumen extending from the distal end to the proximal end. The introducer sheath may also include a tab formed at the distal end and extending distal to the lumen, and a frangible portion extending between the distal end and the proximal end.

Abstract: A medical device that may include a plurality of branch members forming a basket movable between a collapsed configuration and an expanded configuration is disclosed. Each branch member may include a proximal coil, and a distal coil. Each branch member may also include an uncoiled portion disposed between the proximal coil and the distal coil, and a movable portion.

Abstract: According to an example of the present disclosure, a retrieval device having a contracted state and an expanded state may include at least three support members each having a lumen, a fixed proximal end, and a movable distal end, and at least two members movable relative to the support members. Each movable member may include a first end and a second end and extending distally through a lumen of a support member and proximally through a lumen of a different support member. The device may include a stop located at the second end of at least one movable member to restrict movement of the second end after moving a distance distally during movement of the retrieval device toward the expanded state.
