MONOPOLAR RF SUBCUTANEOUS FAT TREATMENT SYSTEMS AND METHODS

摘要

A subcutaneous fat treatment system and method. An electrode is for application to a patient's epidermis above subcutaneous fat to be treated. There may optionally be a cooling subsystem for cooling the electrode. A sensor such as a microwave radiometer measures the temperature of the subcutaneous fat to be treated. In addition or in the alternative, a subcutaneous fat thickness measurement may be used. A radio frequency source is for applying radio frequency energy to the electrode. A controller subsystem is responsive to the sensor and/or the subcutaneous fat thickness measurement and controls the radio frequency source to determine the thermal dose applied to the subcutaneous fat being treated and automatically adjust the radio frequency energy supplied to the electrode subjecting the subcutaneous fat to a thermal dose of between 0.1 and 10.0.
