20110196438 | THERAPY DEVICE AND METHOD FOR TREATING UNDERLYING TISSUE USING ELECTRICAL AND ACOUSTIC ENERGIES - A device for subcutaneous adipose tissue skin treatment applies both radio frequency energy (RF) and ultrasound energy (US) into the skin from a single electrode. The electrode may be cooled via a chilled liquid cooling system, thereby indirectly also cooling the skin. An infrared thermometer on the device may measure skin temperature. A passive electrode may be placed on the patient's skin in a location remote from the treatment site. | 2011-08-11 |
