1. A method of treating obstructive sleep apnea in a patient comprising:
- a. monitoring the respiratory cycle of said patient to determine the inspiration portion;
b. generating stimulation pulses corresponding with said inspiration portion of said respiration cycle;
c. monitoring upper airway patency during said inspiration portion of said respiration cycle; and
,d. adjusting the intensity of said stimulation pulses in response to the results of said upper airway patency monitoring step to maintain normal patency of said upper airway.

Abstract
A method of and apparatus for controlling one or more parameters of an electrical stimulation generator in response to measured results of the stimulation. In the preferred mode, this technique is employed in a system for the treatment of obstructive sleep apnea. Sensors are used to determine the effectiveness of the stimulation. Amplitude and pulse width are modified in response to the measurements from the sensors.

6. An apparatus for treating obstructive sleep apnea comprising:
-
a. means for generating signals to stimulate upper airway muscle tissue of a patient; b. means coupled to said generating means for timing said signals to produce stimulation of said upper airway muscle tissue during inspiration by said patient; c. means for monitoring efficacy of stimulation of said signals; and
,d. means coupled to said monitoring means and said generating means for adjusting intensity of said signals to efficiently increase patency of said upper airway of said patient. - View Dependent Claims (7, 8, 9, 10, 11)
