ABSTRACT:
The method for the localized destruction of soft structures using negative pressure elastic waves, comprises the steps of generating at a predetermined rate comprised between a few Hz and 3 KHz, trains of elastic pressure waves, said waves having a frequency between 0.3 and 10 MHz, each of said trains having a duration between 1 microsecond and 1 millisecond and comprising negative going oscillations; focussing said waves into a beam; transmitting and directing said beam onto the target through a liquid coupling medium and adjusting the power of said elastic pressure wave at a predetermined value.
