Abstract: A system for retrieving material or objects from a biological vessel is provided. the system includes an elongated braid structure configured for transitioning between collapsed and expanded states, the elongated braid structure surrounding a lumen having a distal opening when in the expanded state. The system further includes a closure wire positioned along a length of the elongated braid structure, the closure wire being actuatable to pull inward a distal portion of the elongated braid structure and thereby at least partially close the distal opening.
