Abstract
Vascular catheters include ultrasonic imaging capability and optical waveguides for delivering laser energy for ablating vascular obstructions. The ultrasonic imaging capability comprises a fixed ultrasonic transducer which directs ultrasonic energy at a reflective surface on a rotating element. The rotating element allows the interior of the blood vessel to be scanned prior to the application of laser energy to ablate the obstruction.
