Abstract
A magnetic neural stimulator is disclosed for the stimulation of biological tissue. The stimulator includes an inductive stimulation coil, an energy storage capacitor, a firing device and a charging circuit. The energy storage capacitor is charged by the charging circuit to a voltage level which is greater than the voltage level supplied to the charging circuit. The energy storage capacitor is partially discharged into the stimulation coil thereby producing a magnetic pulse. The charging and discharging of the capacitor is continuously performed so as to produce a plurality of high frequency magnetic pulses. The stimulation coil and the energy storage capacitor operate in a resonant manner under a control circuit which performs timing and gating functions.
