1. A method of eliminating the need for at least one surgical incision for the treatment of a medical condition by creating a plurality of ablative lesions in an area of tissue of a patient, the method comprising:
- positioning an ultrasound emitting member adjacent the area of tissue;
emitting ultrasound energy from the ultrasound emitting member into the area of tissue;
focusing the ultrasound energy simultaneously at a plurality of spaced focusing zones contained in the area of tissue;
heating the area of tissue at the focusing zones with the focused ultrasound energy to form the plurality of ablative lesions in the area of tissue; and
removing the ultrasound emitting member from adjacent the area of tissue.
