ABSTRACT:
A method and system for treating dysphagia using electrical stimulation of a human's or animals's vagus nerve, or recurrent laryngeal nerve, or both to cause glottic or vocal fold motion in humans or animals. Stimulation is caused by utilizing a power source; an external controller for generating and providing an output signal having a given intensity, frequency, and pulse duration; an output protector circuit for limiting the intensity of the output signal; a treatment duration circuit for controlling the duration of operation of the external controller, a ramp control circuit for controlling the intensity of the output signal; and a monitor portion for displaying operating parameters of the device. The external controller regulates the intensity, the frequency, and the pulse duration of the output signal in accordance with a procedure for treating dysphagia.
