Controlled volumetric heating of subcutaneous adipose tissue using a novel radiofrequency technology

Abstract

As the frequency increases (i) the electric potential at the skin surface decreases from the center to the edge of the RF applicator; (ii) the difference between the power absorbed at the top and bottom of the subcutaneous fat layer increases; (iii) the difference between the power absorbed at the center and the periphery of the exposed subcutaneous fat volume also increases; and, consequently, (iv) the size of the heated subcutaneous fat volume decreases. Such a device when used in humans may allow for differential delivery of heat to varying fat thicknesses and anatomic areas.
