Claims5
A system for ablating tissue with ultrasound energy, comprising:
- a plurality of ablating elements which each emit focused ultrasound energy;
- and
- a control system coupled to the ablating elements, the control system controlling activation of the ablating elements and programmed to automatically change the frequency of the ablating elements when ablating the same tissue structure, each ablating element being activated to ablate tissue at a first frequency for a first plurality of time periods and to ablate the same tissue at a second frequency which is a predetermined frequency different than the first frequency, for a second plurality of time periods.
