Title:
POWER PARAMETERS FOR ULTRASONIC CATHETER
Document Type and Number:
WIPO Patent Application WO/2010/003130
Kind Code:
A3
Abstract:
In one embodiment of the present invention, a method of applying ultrasonic energy to a treatment site within a patient's vasculature comprises positioning an ultrasound radiating member at a treatment site within a patient's vasculature. The method further comprises activating the ultrasound radiating member to produce pulses of ultrasonic energy at a cycle period T≤ 1 second. The acoustic parameters such as peak power, pulse width, pulse repetition frequency and frequency or any combination of them can be varied non-linearly.
