Abstract
An ultrasonic angioplasty device includes a catheter and a connector assembly for interconnecting an ultrasound transmission member to an ultrasound transducer. A rotation control device is provided that prevents the ultrasound transmission member from rotating relative to the catheter. Rotation is prevented by a fastener aligning the connector assembly with the elongated catheter body, or a key member that fits in a correspondingly shaped slot in a proximal shaft portion of the catheter, for preventing rotation of the connector assembly relative to the catheter.
