Dyb nervestimulator

An apparatus for providing deep nerve stimulation to a patient includes a housing for supporting deep nerve stimulation coils. The housing includes a wall with an outer surface for being presented toward the patient to apply the stimulation. A primary coil is supported in a primary chamber of the housing adjacent an inner surface of the wall, opposite the outer surface. Ribs are disposed between the primary coil and the inner surface and upon which the primary coil rests. The ribs define channels through which coolant can be directed to cool a bottom surface of the primary coil during use, the bottom surface of the primary coil being closest to the patient side wall. The primary coil is adapted when energized to produce a broad and deeply penetrating magnetic field capable of hitting a target area of the patient. The secondary coil is configured and arranged to, when energized, focus and shape the field produced by the primary coil so that we can maximize the field strength at the target deep nerve, while minimizing the field at near off-target sensitive areas.
