1. A method of positioning an electrode cuff on a hypoglossal nerve of a patient, the method comprising:
- positioning the electrode cuff at a first location on the hypoglossal nerve, wherein the electrode cuff includes a plurality of electrode contacts;
delivering a first electrical stimulation to the hypoglossal nerve via the electrode cuff at the first location on the hypoglossal nerve;
monitoring an upper airway of the patient at a first time to evaluate a positioning of the electrode cuff at the first location on the hypoglossal nerve, wherein monitoring the upper airway includes visualizing the upper airway, and wherein the monitoring at the first time indicates that a predetermined response is not fully achieved; and
repositioning the electrode cuff at a second location on the hypoglossal nerve, wherein the second location on the hypoglossal nerve is different from the first location on the hypoglossal nerve;
delivering a second electrical stimulation to the hypoglossal nerve via the electrode cuff at the second location on the hypoglossal nerve; and
monitoring the upper airway of the patient at a second time for the predetermined response to evaluate a positioning of the electrode cuff at the second location on the hypoglossal nerve.

11. A method of positioning an electrode on a hypoglossal nerve of a patient, the method comprising:
-
positioning the electrode at a first location on the hypoglossal nerve; delivering an electrical stimulation to the hypoglossal nerve; confirming desired positioning of the electrode by monitoring an upper airway of the patient for a desired response, wherein monitoring the upper airway includes visualizing the upper airway with an imaging device; and repeating the steps of positioning the electrode and delivering an electrical stimulation until the desired response is observed. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of positioning an electrode cuff on a hypoglossal nerve of a patient, the method comprising:
-
evaluating a first response of an upper airway of the patient to a first stimulation signal delivered to a first location on the hypoglossal nerve via the electrode cuff, the first response comprising a first magnitude of movement of upper airway tissue; repositioning the electrode cuff from the first location on the hypoglossal nerve to a different second location on the hypoglossal nerve; and evaluating a second response of the upper airway of the patient to a second stimulation signal delivered to the second location on the hypoglossal nerve via the electrode cuff, the second response comprising a second magnitude of movement of upper airway tissue, the second magnitude being greater than the first magnitude. - View Dependent Claims (19, 20, 21)
