1. A method of stimulating a hypoglossal nerve comprising:
- chronically implanting a nerve cuff electrode on a portion of the hypoglossal nerve;
sensing a signal corresponding to respiration;
detecting one or more expiratory onsets from the sensed signal;
calculating a future inspiratory onset from the detected one or more expiratory onsets; and
delivering a stimulus to the portion of the hypoglossal nerve via the nerve cuff electrode, wherein the stimulus delivery begins a predetermined amount of time prior to the calculated future inspiratory onset.

Abstract
A method of stimulating a hypogossal nerve including chronically implanting a nerve cuff electrode on a portion of the hypoglossal nerve. The method may further include sensing a signal corresponding to respiration and detecting expiratory onset from the sensed signal. Moreover, the method may include delivering a stimulus to the portion of the hypoglossal nerve via the nerve cuff electrode, wherein the stimulus is delivered as a function of the detected expiratory onset.

13. A device for stimulating a hypoglossal nerve, comprising:
-
a neurostimulator for generating an electrical stimulus signal; a lead connected to the neurostimulator, the lead having a nerve cuff electrode for delivering the electrical stimulus to a portion of the hypoglossal nerve; and an algorithm contained in the neurostimulator, wherein the algorithm is configured to begin stimulus delivery a predetermined amount of time prior to a predicted future inspiratory onset, wherein the predicted future inspiratory onset is calculated from one or more expiratory onsets detected from a sensed respiratory signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
