Abstract
A method for treating body tissue using acoustic energy includes identifying a target focal zone of tissue to be treated, delivering a first pulse of acoustic energy from a transducer to generate bubbles in a tissue region located distally, relative to the transducer, of a focal center of the target focal zone, and delivering a second pulse of acoustic energy from the transducer in the presence of the bubbles generated by the first pulse, the second pulse focused at the focal center to generate thermal ablation energy. In a further embodiment, a method of treating body tissue using ultrasound energy includes identifying a target focal zone to be treated and delivering a plurality of pulses of acoustic ablation energy to locations distributed symmetrically in or proximate a focal plane about the focal center of the target focal zone.
