<p>PROBLEM TO BE SOLVED: To easily form a branch shape balloon by putting a stent having an opening part corresponding to the opening part formed in an extension possible and cylindrical stent through the latter opening part, putting the balloon through each stent and arranging the balloons in a branch shape. SOLUTION: The center opening part 102 is formed in the extension possible and cylindrical stent 101 and the center opening part 102 is used as the passage of the same sized stent 103 in a non-extension state. One 151 of the two balloons is put through the stent 101, the upper stent 103 is extended from the opening part 102 formed in the stent 101 and the other balloon 152 is put through it. The opening part 104 facing the lower stent 101 is also formed in the upper stent 103. Thus, when the second stent 103 is inserted to the first one 101, the both stents 101 and 103 are arranged in a state they are mutually opposed and brought into contact with each other and this combination body is guided to the inner part of a human body.</p> |
