Abstract
The method and device of the present invention for pain relief using ultrasound waves in combination with cryogenic energy includes a generator and a transducer to produce ultrasonic waves and a cryogenic source to produce cryogenic energy. Ultrasound waves are delivered to the target in combination with cryogenic energy. Ultrasound waves and cryogenic energy can be delivered to the target from the radial side of the ultrasound horn and/or tip or can be delivered from the distal end of the ultrasound tip. Cryogenic energy can also be delivered directly to the target through a central orifice. Ultrasound energy can also be delivered through a cryogenic spray at the distal end. The use of ultrasound waves in combination with cryogenic energy can provide an analgesic effect.
