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.

A system for retrieving material or objects from a biological vessel comprising an elongated braid structure that:
- includes a set of wires that includes a plurality of helically wound wires crossing a plurality of counter-helically wound wires to define a wall surrounding a lumen, the lumen having a distal opening at a distal end of said elongated braid structure;
- is configured for transitioning between collapsed and expanded states;
- and
- is coated internally with a cover such that a suctioning force can be applied to the distal opening when said elongated braid structure is in said expanded state,
- wherein:
- the system comprises an other wire arranged along the braided structure and back along the braided structure alongside itself in a double spiral configuration;
- and
- the distal end of said elongated braid structure forms a plurality of wire loops that are formed from wires of the set and that are angled outwardly with respect to the wall.
