Abstract:
Techniques for operating a subcutaneous implant device are disclosed. The implant device can be formed of a non-magnetic material that is compatible with diagnostics such as magnetic resonance imaging (MRI) and can include a rotor element that rotates under the influence of an external magnetic field. The implant device includes a tension relief mechanism for relieving excessive force applied between the implant device and a portion of a patient's tongue. A non-implanted device can include a stator and drive circuitry for generating the external magnetic field. The non-implanted device can receive a user command and can vary the external magnetic field based on the command. When activated by the magnetic field, the implant device can change its operating state to interact with the patient's body.
