Power parameters for ultrasonic catheter
First Claim
1. A method of operating an ultrasonic catheter which comprises at least one ultrasonic element, the method comprising the steps of:
- advancing the ultrasonic catheter to a treatment site in a patient'"'"'s vascular system or tissue;
driving the at least one ultrasonic element to generate ultrasonic energy;
delivering a therapeutic compound to the treatment site through the ultrasonic catheter; and
varying a peak power and a physiological parameter of the ultrasonic element, and wherein varying the peak power and the physiological parameter comprises;
repeatedly cycling the peak power through a first set of preset values between a preset minimum value and a preset maximum value; and
repeatedly cycling the physiological parameter through a second set of preset values.

Abstract
An ultrasound catheter system and a method for operating an ultrasonic catheter at a treatment site within a patient'"'"'s vasculature or tissue are disclosed. The ultrasound catheter system comprises a catheter having at least one ultrasonic element and a control system configured to generate power parameters that drive the at least one ultrasonic element to generate ultrasonic energy. The control system is configured to vary at least one of the power parameters and at least one physiological parameter by repeatedly cycling the power parameter and the physiological parameter through two set of values.
