An electrosurgical angioplasty catheter with ultrasonic enhancement is described. It comprises an elongated, flexible plastic tubular body having located at its distal tip an electrode structure for effecting rf cutting along with a transducer for ultrasonically driving the rf cutting electrodes and the support thereof. The electronics module for driving the cutting electrodes and the ultrasonic transducer also includes means for receiving echo signals picked up by the transducer whereby Doppler flow readings and ultrasound imaging of the blood vessel being worked upon can be obtained.
