Vascular catheters designed to obtain intravascular images of the coronary arteries using optical coherence tomography (OCT). These catheters typically consist of a plastic tube with a fiberoptic core and a lumen for saline and/or contrast media injection; the catheter delivers near-infrared light and performs a fast (e.g., 100 MB/sec) data sampling rate to perform measurements in a few seconds. OCT coronary artery imaging catheters are attached to OTC laser scanning system to assess complex lesions inside the arteries, facilitating the evaluation of atherosclerotic plaque components and permitting internal measurements in the coronary arteries such as lesion length and size of appropriate stents in patients that are or will be candidates for coronary artery catheterization procedures.
