Patent ID: 8577467

Claim:
A sleep disordered breathing therapy device, comprising: a skin patch configured for temporary affixation on a region including at least one of a neck, an underside of a chin, and a head of a subject; a primary antenna associated with the skin patch; at least one processor associated with the skin patch and configured for electrical communication with a power source; the at least one processor further configured to communicate with an implant unit via the primary antenna when the implant unit is implanted in at least one of the neck and the head of the subject in a location proximate to a hypoglossal nerve, and to determine a degree of coupling between the primary antenna and a secondary antenna associated with the implant unit based on relative movement between the primary antenna and the secondary antenna when the skin patch is affixed to skin of the subject, and to regulate delivery of power from the power source to the implant unit such that power delivered to the implant unit varies based on the degree of coupling between the primary antenna and the secondary antenna.
