Abstract:
1. An external ultrasound lipoplasty (EUL) system comprising a transmitter and a multichannel transducer comprising an electronic focus and operated in a 0.5 MHz to 20 MHz frequency range, wherein the transmitter is configured to multi-zone focus by electronically sweeping the focus of the transducer such that it generates pulses of acoustic energy at different focal lengths at different times within a user or manufacturer selected depth range between about 1 mm and 30 mm during a use by controlling a plurality of attributes selected from the group consisting of an aperture size, a frequency, a transmit voltage, a delay, an apodization, a pulse repetition frequency and a pulse length for each swept depth to not irreversibly affect tissue of a patient beyond the user or manufacturer selected depth range when an acoustic pressure and intensity of said EUL system is high enough to substantially emulsify fat within said selected depth range of the tissue.
