An apparatus and method in which the portions of the labyrinth associated
with the labyrinthine sense and/or the nerves associated therewith are
stimulated to perform at least one of the following functions: augment or
control a patient's respiratory function, open the patient's airway,
induce sleep, and/or counteract vertigo. In one embodiment, the
vestibular stimulating system of the present invention includes 1) a
stimulation element that performs the actual stimulation of the tissue,
2) a sensor to detect a physiological condition of the patient, and 3) a
power/control unit that receives the signals provided by the sensor and
causes stimulation energy to be provided to the stimulation element at an
appropriate timing, level, pattern, and/or frequency to achieve the
desired function. However, the present invention also contemplates
eliminating the sensor in favor of applying a predetermined pattern of
stimulation to the patient.
