<P>PROBLEM TO BE SOLVED: To provide an inducing catheter of laser fiber capable of securely fixing a laser irradiation part of laser fiber to an affected part to activate a photosensitive substance PF, thereby securely executing the therapy of an aimed narrow part. <P>SOLUTION: In the inducing catheter 41 of laser fiber, an insertion port 47 for laser fiber LF is formed on the rear end of an outside tube 54, a photosensitive substance PF is fixed on the outer periphery of a balloon 52, a positioning marker 48 is set (A) on one site on the outer periphery of an inside tube 55 at the center of the balloon 52, or (B) on two sites at equal distances from the center of the balloon 52 on the outer periphery of the inside tube 55 on both sides of the balloon 52, and a stopper 43 of the laser fiber LF is set within the inside tube 55 at the center of the balloon 52 so that the tip end of the laser fiber LF stops at the center of the balloon 52. <P>COPYRIGHT: (C)2009,JPO&INPIT |
