| 摘要 |
Atherosclerotic vascular disease is treated by exposing the interior of an artery or vein to visible or ultraviolet light of a selected spectrum to thereby sterilize the artery, eradicating infectious pathogens and reverse the pathogenesis of atherosclerotic artery disease. A fiber optic bundle positioned via an intra-arterial catheter is connected to an appropriate light radiation source located outside of the body during treatment. In another form, the light energy is produced by means of a light energy source located at the distal tip of the instrument shaft positioned centrally within the atherosclerotic plaque formation. In this case, the power source at the distal tip of the instrument can be a light emitting diode (LED) or a transparent tube containing a chemilumlumenescent substance for producing cool light energy within the vessel to destroy the pathogenic microorganisms in the surrounding plaque or vessel without damage to the body tissue of the patient.
