A method and apparatus is described for eliminating atherosclerotic vascular disease 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. The light energy can be supplied through a fiber optic bundle positioned via an intra-arterial catheter that is connected to an appropriate light radiation source located outside of the body during treatment. In another form of the invention, 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 during treatment. In this case, the power source at the distal tip of the instrument can, for example, be a light emitting diode (LED) or a transparent tube containing a chemical or 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 issue of the patient.
本文描述了一种消除动脉粥样硬化性血管疾病的方法和设备,其方法是将动脉或静脉内部暴露于选定光谱的可见光或紫外线中,从而对动脉进行消毒,消灭感染性病原体,并逆转动脉粥样硬化性疾病的发病机制。光能可通过光纤束提供,光纤束通过动脉内导管定位,导管在治疗过程中与位于体外的适当光辐射源相连。在本发明的另一种形式中,光能是通过位于治疗过程中动脉粥样硬化斑块形成中心的器械轴远端产生的。在这种情况下,位于器械远端顶端的电源可以是发光二极管(LED)或含有化学或化学发光物质的透明管,用于在血管内产生冷光能,以消灭周围斑块或血管中的病原微生物,而不会对患者的身体问题造成损害。
