Abstract
A method of removing human body fatty tissue includes inserting an ultrasonic aspirating probe into the body in the area of the fatty tissue between the flesh, including blood vessels and arteries, and the muscle. The probe is ultrasonically vibrated at high frequencies and low amplitudes creating localized tissue separation and frictional heat. This heat causes the fatty tissue surrounding the probe to melt. The probe is specially adapted to provide a localized flow of irrigating fluid. This fluid serves to emulsify the melted and separated fat. The emulsified fat is then aspirated through specially designed orifices from the body using suction.
