A method to deliver focused ultrasound energy from a position outside a skin of a patient to a nerve surrounding a blood vessel, includes placing the patient on a table in a substantially flat position, moving a transducer into a position inferior to ribs, superior to an iliac crest, and lateral to a spine of the patient, maintaining the transducer at the position relative to the patient, and delivering focused ultrasound energy through the skin of the patient without traversing bone, wherein the direction of the focused ultrasound is directed from a lower torso to an upper torso of the patient.
