Remote Monitoring and Updating of a Medical Device Control Unit

A control unit, comprising:

• a communications interface;
• a memory;
• and
• at least one processing device configured to:
• cause application of a control signal to a primary antenna associated with a unit external to a subject's body, wherein application of the control signal causes transmission of a modulation signal from the primary antenna to a secondary antenna associated with an implant unit configured for location in the subject's body, the implant unit also being configured to modulate a hypoglossal nerve in response to the control signal applied to the primary antenna;
• monitor a feedback signal indicative of the subject's breathing;
• store, in the memory, information associated with the feedback signal;
• cause transmission of the stored information, via the communications interface, to a location remote from the control unit;
• receive an update signal, via the communications interface, from the location remote from the control unit, the update signal being generated in response to the transmitted, stored information;
• and
• cause application of an updated control signal to the primary antenna based on the update signal.
