Catheters, Vascular, Optical Coherence Tomography Imaging

Definition : Vascular catheters designed to obtain intravascular images using optical coherence tomography (OCT). These catheters typically consist of a plastic tube with a fiberoptic core; the catheter delivers near-infrared light and performs a fast (e.g., 100 MB/sec) data sampling rate. OCT imaging catheters are attached to an OTC laser scanning system to assess complex lesions inside the vasculature, to facilitate the evaluation of atherosclerotic plaque components and permit internal measurements. These devices assess lesion length and size of appropriate stents in patients that are, or will be, candidates for intravascular procedures. Dedicated catheters intended for OTC in the coronary arteries are available.
