Ultrasound Therapy Systems, Angioplasty
Definition : Ultrasound therapy systems that deliver energy into the vessels to eliminate areas of narrowing (i.e., angioplasty). These systems include a radio-frequency generator (frequency of 20 kHz is typical), ultrasonic transducers, and a catheter. Some systems include a ball-tipped wire that act as an acoustic wave guide, transmitting the energy to the target areas within the artery; other systems use small ultrasonic transducers on the distal tip of a catheter that are excited to produce the ultrasonic waves. Ultrasound angioplasty systems are mostly used in total occlusion and calcified plaques and to facilitate balloon angioplasty.
