ABSTRACT:
This invention is directed to a simple, non-invasive method and device for treating dysphagia and artificially promoting swallowing by electrical stimulus. In the present invention, a plurality of electrodes are selectively placed in electrical contact with tissue of a pharyngeal region of patient and a series of electrical pulses in electrical contact with each of the plurality of electrodes with a generator. The generator includes a pulse rate modulator for generating each of the electrical pulses having a frequency generally fixed at 80 hertz, a pulse width modulator for generating each pulse of the series of electrical pulses at a duration generally fixed at 300 microseconds, and a governor for regulating the electrical pulses such that at least one of current so as not to exceed 4.4 milliamps RMS or power so as not to exceed 9.6 MW RMS. The electrical pulses selectively stimulate muscles located proximate to the selectively placed electrodes to initiate swallowing.
