<P>PROBLEM TO BE SOLVED: To provide a living organ dilator having a stent which is attached while compressed on a balloon, which does not have a bending part to be largely deformed when attached or when dilated, which hardly gives material fatigue to the bending part and which has stable shape retaining properties for a long period after retention. <P>SOLUTION: The living organ dilator 1 includes a balloon catheter 2 with a balloon 3, and the stent 10 attached as compressed on the balloon 3. The stent 10 has a plurality of bending parts 21 which are deformed when compressed and a plurality of bending parts 22 which are not substantially deformed when compressed. When the balloon 3 is expanded, the stent 10 is in an expanded state as the bending parts 22 which are not substantially deformed when compressed are more largely deformed than the bending parts 21 deformed when compressed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
