Method of transluminal laser revascularization of cerebral blood vessels having atherosclerotic lesions

摘要

A method of transluminal laser revascularization of cerebral blood vessels having atherosclerotic lesions by introducing into the affected lumen a microcatheter device composed of a plurality of coaxial microcatheters moveably inserted one into the other and guiding through the catheters a laser-powered lightguide optical fiber, the end face of which is positioned at an optimal distance from the occlusive tissues which are then deteriorated by laser radiation at a relatively high laser power from 20 to 35 W.
