摘要： Catheter of such a structure that Ti—Ni superelastic allow (SEA) tube has its outside covered with thin-film silicone rubber tube. The SEA tube at part whose flexion is desired is wrought to cut off multiple grooves (crenas) with thin joints left. The covering with the silicone rubber tube is effected without the use of its front end portion in the covering. When a negative pressure is applied to physiological saline placed therein, the front end portion works as a valve, and the silicone rubber tube at the wrought part yields inward so that flexion of the catheter occurs at that part.
