Attorney, Agent or FirmInternational ClassesA61N 002/00A61N 002/02 AbstractA PEMF stimulation therapy system uses a PEMF transducer coil for generating PEMF stimulation signals and includes a single-winding transducer coil. A drive circuit recovers flyback energy from the single-winding transducer coil and dumps the voltage to a voltage supply equal to a predetermined high voltage that differs from supply voltage. This permits sequencing the current through the PEMF transducer coil in a positive direction and then negative direction. The result is a PEMF stimulation therapy system that may use a commercially available, low-cost battery for power and that is significantly lighter and more portable than known PEMF stimulation therapy systems. | |
