Patent ID: 8262591

Claim:
A method for emulsifying subdermal fat of a patient comprising: topically applying, a hand-held high intensity focused ultrasound transducer to skin via a liquid or gel, said focused ultrasound transducer comprising a transmitter and a transducer operated in a 0.5 MHz to 20 MHz frequency range, wherein the transducer comprises a transducer aperture and an electronic focus; and electronically sweeping a focal line of ultrasound energy within a user or manufacturer selected depth range between about 1mm and 30mm. wherein the transducer aperture and a frequency are configured to not irreversibly affect tissue of the patient beyond the user or manufacturer selected depth range when an acoustic pressure and intensity of the ultrasound is high enough to substantially emulsify a subdermal fat within said selected depth range of the tissue, and wherein the focal line is one of a curved focal line and a focal line that is not parallel to a relative axis of the transducer.
