PROBLEM TO BE SOLVED: To freely provide an endless cylindrical stent, which can be easily fixed and has the arbitrary number of vents by supplying a wire to a user in the form of semiproduct without bonding the fore end and rear end of zigzag- folded wire. SOLUTION: A zigzag-shaped wire 11 for stent preparation is formed while using a stainless steel wire having the diameter of about 0.6mm. When preparing the stent of 8 vents while using a stent molding table 11, for example, a 1st bent part 3 is inserted into the 1st hole of lock holes 13 on a pedestal 12 on one side. Next, a 2nd bent part 3 is inserted into the 1st hole on a pedestal 12 on the other side. The bent part 3 is inserted in the order of 3rd, 5th, 9th, 11th, 13rd and 15th holes. Thus, the zigzag-shaped wire 1 of 8 vents is molded cyrindical and round. After the final bent part 3 is inserted into the 15th hole, a connector 4 mounted on one end is moved in the direction of arrow A and connected to another end 2'. Thus, the endless cylindrical stent having arbitrary number of vents can be easily formed. |
