PROBLEM TO BE SOLVED: To provide a living organ dilator which has two self-expanding stents and can excellently indwell the respective stents at a target part.SOLUTION: The living organ dilator 1 includes: the first stent 3 and second stent 4 of a self-expanding type; a tubular body provided with a guide wire lumen 21; and a stent storage cylindrical member 5 for storing the stents 3 and 4 inside a distal end part and exposing the stents 3 and 4 by moving them to the proximal end side. The second stent 4 is disposed more on the proximal end side than the first stent 3 by a prescribed length. The biological organ dilator 1 is provided with a first proximal end direction movement suppression part 31 close or abutted to the rear end of the first stent 3 and provided with an imaging property and a second proximal end direction movement suppression part 41 close or abutted to the rear end of the second stent 4 and provided with an imaging property. |
