PROBLEM TO BE SOLVED: To stop insertion and shape restitution and recover easily when an indwelling shape abnormality occurs, by providing ring recovery sections on both ends of the frame in an intravascular indweller intended for hemostasis, constriction control, and thrombus movement control by making a catheter indwell intravascularly. SOLUTION: An intravascular indweller is formed by providing a recovery section 2 at one or two ends of the frame 4 of an intravascular indweller. To use it, the frame 4 is wound around an insertion catheter and a fixing line is run to the clearance of the frame 4 and the recovery portion 2 and fixed to the insertion catheter. Then the insertion catheter is advanced along a guide wire and stopped at an intended portion. By pulling the fixing line extracorporally, the frame 4 is separated from the insertion catheter by it's own restitutive force and is retained intravascularly. To stop the restitution of the frame 4 and remove it extracorporally, the frame 4 is removed extracorporally by stopping pulling of the fixing line and pulling the insertion catheter extracorporally. |
