  • Patent number: 5165773
    Abstract: A flexible light guide consists essentially of a flexible tube made of an amorphous fluoropolymer based on a combination of terafluoroethylene and a fluorinated cyclical ether, and a transparent liquid filling the tube. The liquid has an index of refraction which is higher than that of the material of the tube. The light guide may be provided with means for continously passing the liquid through the tube. In this case, the liquid may be physiological sodium chloride solution and the light guide may be a part of an endoscopic illumination device useful for endoscopic coagulation.
