<p>PROBLEM TO BE SOLVED: To realize the arrangement in lumen with different sizes by providing a first portion having a first diameter and a second diameter larger than the first one and a second portion linked to the first portion and having a third diameter and a fourth diameter greater than the third one, wherein the second diameter differs from the fourth diameter. SOLUTION: The first portion 12 of a stent 10 has a length l1 and a diameter d1 . The second portion 14 has a length l2 and a diameter d2 . Portions 12, 14 are connected with each other via a connector 16. The first portion 12 has a long slot 18 with a length s1 and the second portion 14 has a long slot 20 with a length s2 . When the stent 10 is placed in connection portion between iliac artery and aorta, the size of the first portion 12 enlarges to be able to accept the aorta, the size of the second portion 14 enlarges to be able to accept the iliac artery whose size is different from that of the aorta.</p> |
