Abstract

The present invention relates to an ultrasound assisted cryogenic surgical instrument, more particularly, to methods and devices utilizing ultrasound energy for treatment of the endometrium to control heavy uterine bleeding (menorrhagia) or other conditions. The device of the present invention comprises an ultrasound generator, an ultrasound transducer, a transducer tip at the distal end of the ultrasound transducer, and a radiation surface. Ultrasonic radiation is directed into the tissue being ablated. A cryogenic solution is circulated through the ultrasound tip to transfer thermal energy away from the tissue to freeze the tissue being ablated by providing a synergistic effect with the ultrasonic radiation.
