Abstract
One aspect of the invention provides a method of stimulating a nerve in tissue of a patient. The method includes the following steps: applying a focused ultrasound beam to the tissue; applying a first magnetic field to the tissue; and applying a second magnetic field to the tissue, the ultrasound beam and the first and second magnetic fields combining to stimulate the nerve. Another aspect of the invention provides a nerve stimulation device having two magnetic coils of opposite polarity each adapted to generate a magnetic field in a patient's tissue, the coils being positioned to generate a substantially toroidal magnetic field within the patient's tissue; and an ultrasound source adapted to transmit a focused ultrasound beam into the patient's tissue.
