療の向上が図れていなかつた。(Prior art and its problems) Conventionally, this type of balloon-equipped endoscopic catheter has a plurality of lumens 10 inside, as shown in FIG.
1, 102... A balloon 200 is attached to the tip of the catheter body 100 so as to cover the tip, and an endoscope, laser fiber (not shown), etc. is inserted into the lumens 101, 102... Previously, the balloon 200 was inflated within a blood vessel to secure a field of view, and while checking with an endoscope, a laser beam or the like was irradiated from within the balloon 200 to the affected area, such as a lesion, for treatment. Since the balloon 200 was used to irradiate the patient through the laser beam, the laser effect was halved by the balloon 200, making it impossible to improve the treatment.

There is one in which a balloon 400 is attached to the outer peripheral tip part 301 of the body 300, and the tip surface 302 of the main body 300 is open, but this allows the irradiation of laser beams etc. to be directly irradiated onto the affected area without anything blocking the irradiation. Since the endoscope part is exposed, it is difficult to secure a field of view and accurate diagnosis cannot be performed, and as a result, reliable irradiation with laser beams or the like cannot be performed.
