Abstract
Described herein are atherectomy catheters, systems and methods of use. The atherectomy catheters may include a driveshaft within an elongate body. An optical fiber may run through the driveshaft and have a distal end that is attached to an opening of a cutter at distal end of the driveshaft. The cutter and the optical fiber may be rotated respect to the elongate body by rotating the driveshaft with respect to the elongate body. The driveshaft may be longitudinally displaced to expose a distal cutting edge of the cutter for cutting tissue or plaque from a vessel lumen. Images of the vessel lumen collected through the opening of the cutter may be captured in real time with the optical fiber.
