PURPOSE:To uniformly position the emitting end parts of laser conductive fibers and to enhance the insertion part thereof by joining a multi-lumen tube to the front end of a single lumen tube, and by inserting and fixing the fibers in through holes in the multi-lumen tube. CONSTITUTION:The insertion part 1 of a laser probe adapted to be inserted in a cavity in a blood vessel or the like, is formed by joining a multi-lumen tube 3 to the front end of a single lumen tube 3. Several through holes 4 are uniformly formed in a multi-lumen tube 3, and the front end parts of laser conductive fibers 5 are inserted and fixed in the through holes 4, respectively. The laser conductive tubes 5 guide laser to the front end of the probe, and have the rear end parts which are led through the single lumen tube 2 connected to the front end of the multi-lumen tube 3, and is connected to a laser device. Accordingly, the emitting ends of the laser conductive fibers 5 may uniformly be positioned, and the flexibility of the insertion part 1 can be enhanced. |
