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.

Device and method for non-invasive, localized neural stimulation utilizing hall effect phenomenon

An apparatus for detecting a discontinuity in a material includes a source of electromagnetic radiation has a wavelength and an intensity sufficient to induce an enhancement in contrast between a manifestation of an acoustic property in the material and of the acoustic property in the discontinuity, as compared to when the material is not irradiated by the electromagnetic radiation. An acoustic emitter directs acoustic waves to the discontinuity in the material. The acoustic waves have a sensitivity to the acoustic property. An acoustic receiver receives the acoustic waves generated by the acoustic emitter after the acoustic waves have interacted with the material and the discontinuity. The acoustic receiver also generates a signal representative of the acoustic waves received by the acoustic receiver. A processor, in communication with the acoustic receiver and responsive to the signal generated by the acoustic receiver, is programmed to generate informational output about the discontinuity based on the signal generated by the acoustic receiver.
