Abstract
A wire for removing an intravascular foreign body according to the present invention is a wire for removing an intravascular foreign body, including: a long or elongated wire body with flexibility; and a capturing portion including a foreign body capturing space which captures a foreign body in a blood vessel therein, the capturing portion being provided on a distal end of the wire body, in which the capturing portion includes: at least two branch wires branching from the distal end of the wire body; and a plurality of filaments bridged between the two branch wires, and at least one of the filaments includes a plurality of curved projections bent in a direction deviated from an extension line of a central axis of a proximal end of the filament. In accordance with the wire for removing an intravascular foreign body according to the present invention, the foreign body in the blood vessel can be surely captured and removed.
