Optical probe for Raman scattering from arterial tissue

摘要

The present invention related to a Raman artery probe diagnostic system and a method of using the system for the diagnosis of vascular disease. A side looking catheter having light delivery and collection optical fibers can deliver infrared light in a radial direction from the catheter to diagnose atherosclerotic plaques in the coronary arteries. A guidewire or guide catheter can be used to deliver the catheter to the region of interest within the artery to evaluate vulnerable plaques.
