Obstructive sleep apnea treatment devices, systems and methods
First Claim
Patent Images
1. A method of treating obstructive sleep apnea, the method comprising:
- chronically implanting an electrode on a nerve innervating an upper airway dilator muscle;
sensing a measure of respiration;
analyzing the measure of respiration to identify onsets of expiration;
calculating a respiratory period from the onsets of expiration;
predicting the onset of a future expiratory phase; and
beginning stimulation of the nerve a fraction of the calculated respiratory period before the onset of the future expiratory phase, and continuing stimulation of the nerve during an entire inspiratory phase, wherein the method is performed without identifying an onset of the inspiratory phase.

15. A method of treating obstructive sleep apnea, the method comprising:
-
obtaining a respiration waveform; analyzing the respiration waveform to identify onsets of expiration; calculating a respiratory period from the onsets of expiration; predicting the onset of a future expiratory phase; and stimulating a nerve to cause dilation of a patient'"'"'s upper airway, wherein stimulation of the nerve begins a fraction of the calculated respiratory cycle period before the onset of the future expiratory phase, and continuing stimulation of the nerve during an entire inspiratory phase, wherein the method is performed without identifying an onset of the inspiratory phase. - View Dependent Claims (16, 17)
