Abstract
The present invention provides a system and method for treating tight, hard-to-cross calcified lesions in which an angioplasty balloon is used to dilate the lesions and provide shock waves to restore normal blood flow in a patient's artery. An exemplary device includes an elongated tube and a balloon wrapped circumferentially around the tube and sealed to a distal end of the tube. During treatment, the device is advanced into a patient's vasculature and the balloon is inflated with conductive fluid such that the balloon is fixed to walls of the vasculature proximal to the calcified lesion. The balloon includes at least one low-profile emitter positioned near the distal end of the balloon, which may be activated to generate shock waves to break loose calcifications in the lesion. After calcium in the tight lesion has been modified, the balloon can be deflated and advanced further into the lesion to continue treatment.
