ABSTRACT:
A novel method for reducing an arteriosclerotic lesion is disclosed in which the electromagnetic energy directed at the lesion is selectively absorbed by a lesion component, e.g. cholesterol. The resulting decomposition of said lesion component leads to reduction of the lesion with minimal risk of damage to blood constituents and adjacent healthy blood vessel tissue. Preferably, monochromatic electromagnetic energy is generated by a laser and is conducted to the vicinity of the lesion by at least one optical fiber.
