1. A method for treating sleep disordered breathing via an implant unit implanted in a location proximate a tongue of the subject, the method comprising:
- receiving a signal associated with the implant unit, the signal being indicative of a tongue movement of the subject;
determining, based on the signal, that the tongue movement is representative of sleep disordered breathing; and
communicating a modulation control signal to the implant unit to activate neuromuscular tissue within the tongue via at least one pair of electrodes associated with the implant unit, wherein the modulation control signal causes modulation of a hypoglossal nerve of the subject in response to an electric field generated by the at least one pair of electrodes,wherein the modulation is confined to a medial branch of the hypoglossal nerve and initiated from a single modulation site along the medial branch to cause modulation of terminal fibers of the medial branch of the hypoglossal nerve.

Abstract
A method for delivering energy as a function of degree coupling may utilize an external unit configured for location external to a body of a subject and at least one processor associated with the implant unit and configured for electrical communication with a power source. The method may determine a degree of coupling between the primary antenna and a secondary antenna associated with the implant unit, and regulate delivery of power to the implant unit based on the degree of coupling between the primary antenna and the secondary antenna.

9. A device for treating sleep disordered breathing via an implant unit implanted in a location proximate a tongue of the subject, the device comprising:
a housing configured for location external to a body of the subject, the housing including a processor further configured to; receive a signal associated with the implant unit, the signal being indicative of a tongue movement of the subject; determine, based on the signal, that the tongue movement is representative of sleep disordered breathing; and communicate a modulation control signal to the implant unit to activate neuromuscular tissue within the tongue via at least one pair of electrodes associated with the implant unit, wherein the modulation control signal causes modulation of a hypoglossal nerve of the subject in response to an electric field generated by the at least one pair of electrodes, wherein the modulation is confined to a portion of the hypoglossal nerve distal of a terminal bifurcation of the hypoglossal nerve into lateral and medial branches. - View Dependent Claims (10, 11, 12, 13, 14, 16)
