ultrasonic angioplasty

ultrasonic angioplasty

The use of ultrasound energy delivered via a fine catheter to break down a thrombotic occlusion in an artery such as a coronary artery. Such methods suffer from the danger that solid particles will be carried by the blood flow to occlude smaller vessels and further damage the heart.
