Systems designed for minimum-access treatment of diseases by applying energy at frequencies over the human upper audible limit (about 20 kHz) and up to several megahertz. These systems typically consist of a radio-frequency generator and an appropriate delivery system that includes cables and/or catheters and electrical to ultrasonic transducers; the power and frequency of the generator and the configuration of the delivery system and transducers depend on the intended use.
