DECOMPOSITION DEVICE FOR CHOLESTEROL ESTER

摘要

PROBLEM TO BE SOLVED: To provide a cholesterol ester decomposition device capable of decomposing and removing cholesterol ester to be the cause of arteriosclerosis in a blood vessel without damaging the blood vessel. SOLUTION: A laser beam from a laser generator 1 is sent through a light guide 2 and an optical fiber 4 to the tip of the optical fiber 4, the laser beam is diffused and irradiated from a light enlarged diameter means 4a at the tip and the cholesterol ester at the closed part 6 of the blood vessel 5 causing the arteriosclerosis is decomposed. The laser beam irradiated at the time is the laser beam of a specified wavelength capable of decomposing the cholesterol ester of 5.75 μm.
