<p>PROBLEM TO BE SOLVED: To provide a tube cutting-typed self-expanding stent to be inserted into vessels. SOLUTION: The stent 50, which has a first rather small diameter to be inserted and guided inside a patients vessel and a second rather larger diameter to arrange itself inside the scope of purpose in the vessel, is composed of plural adjoining hoops 52 that extends between the end 81 of the front opening and the end 82 of the rear opening. These hoops consists of plural loops that connects supporting pillars 60 toward longitudinal direction with the adjoining pillars. Also, stent 50 consists of plural bridging parts 70 that has winding part which bridges the hoop connecting points each other. The hoop connecting points are apart from the longitudinal axis at a certain angle. That is, each bridging part is attached to one loop at the one end and to the loop on the other adjoining hoop at another end. Moreover, the bridging parts 70 curved in nonlinear shapes between the loop connecting points that each of them bridges.</p> |
