LASER CATHETER Abstract of the Disclosure: A laser catheter for leading laser beam to an affected part inside a living body includes a catheter tube having a smooth inner surface and a window member attached to the catheter tube in the vicinity of one end thereof. A liquid injection port is provided in the vicinity of said end of the catheter tube. A transparent liquid is injected and charged into the catheter tube from the liquid injection port, the liquid having a greater refractive index than that of the material that constitutes the catheter tube. Thus, the catheter per se serves as one optical fiber that has its cladding defined by the catheter tube and its core defined by the liquid injected and charged in the inside of the tube, and laser beam is led through this catheter to an affected part in order to destroy it. Accordingly, there is no need to dispose optical fibers around the catheter tube, which means that the overall outer diameter can be reduced, and it is therefore possible to insert the laser catheter into a relatively thin blood vessel. In addition, since the flexibility of the catheter is improved correspondingly, the distal end of the catheter tube can be made to reach a relatively remote affected part in a curved blood vessel.
