Intravascular obstruction removing wire and medical instrument |
摘要 |
An intravascular obstruction removing wire includes an elongate wire body, at least two non-branched wire portions having distal ends and proximal ends which are connected to a distal end of the wire main body, and a plurality of filament portions extending across the wire portions. The non-branched wire portions and the filament portions form a trapping portion. The trapping portion is deformable from a large-diameter state in which the non-branched portions branch to the distal end of the wire body forward in different directions and the filament portions are separated from each other, so that a space surrounded by the non-branched wire portions and the filament portions is formed to trap therein an obstruction in a blood vessel, to a small-diameter state in which the non-branched wire portions are positioned so that a distance between the wire portions is smaller than that of the wire portions in the large-diameter state.
