Patent ID: 7485101

Claim:
In a shockwave method for fragmenting stones or ablating pathological tissue in a living body wherein at least two shockwave generators are arranged in cooperative relation to each other such that timed sequential shockwave pulses from each said shockwave generators are focused to a focal point at said stones or pathological tissue inside the living body, the improvement comprising using at least two medical imaging systems to precisely locate said stones or pathological tissue and aim said shockwave generators in said living body and controlling the collapse of cavitation bubbles produced by said shockwave pulses by controlling the timing and direction of propagation of each timed shockwave pulse so as to avoid damage to adjacent tissue wherein the directions of propagation between said shockwave pulses has an angle between from about 67° to 105° and wherein said shockwave pulses are generated with a delay time between the two shockwave pulses in the range of 1 millisecond to about 100 milliseconds.
