Internal resonance matching between an implanted device and an external device
First Claim
1. An implantable device for treating sleep apnea in a subject, the device, comprising:
- a flexible carrier adapted to be implanted in a region of a genioglossus muscle;
an implantable circuit associated with the flexible carrier, the implantable circuit being adapted to stimulate a hypoglossal nerve and modulate a genioglossus muscle;
an antenna arranged on the flexible carrier and configured to wirelessly receive energy from a location external to a body of the subject and to provide at least a portion of the energy to the implantable circuit;
at least one component associated with the flexible carrier for receiving energy from the implantable circuit; and
a layer encapsulating at least a portion of the flexible carrier, implantable circuit, and the antenna;
wherein the implantable circuit and the antenna have a first internal resonant frequency and are adapted for a resonance frequency variation based on implantation by being configured to have a second internal resonant frequency different from the first internal resonant frequency and matched to an external resonant frequency of an external circuit for communicating with the antenna of the implantable device, when the layer absorbs a fluid and causes a change from the first internal resonant frequency to the second internal resonant frequency.

Abstract
A unit configured for implantation in a subject'"'"'s body may include a carrier, an implantable circuit associated with the carrier, an antenna arranged on the carrier and configured to wirelessly receive energy from a location external to the subject'"'"'s body and to provide at least a portion of the energy to the implantable circuit, and at least one component associated with the carrier for receiving energy from the implantable circuit. Wherein the implantable circuit and the antenna have an internal resonant frequency mismatched from an external resonant frequency of an external circuit, to account for resonance frequency variation as a result of implantation in the subject'"'"'s body.

16. A sleep-apnea therapy unit configured for implantation in a subject'"'"'s body, comprising:
-
a flexible carrier; an implantable circuit associated with the flexible carrier; an antenna arranged on the flexible carrier and configured to wirelessly receive energy from a location external to the subject'"'"'s body and to provide at least a portion of the energy to the implantable circuit; at least one component associated with the flexible carrier for receiving energy from the implantable circuit; and a layer encapsulating at least a portion of the flexible carrier, implantable circuit, and the antenna; wherein the implantable circuit and the antenna have a first internal resonant frequency and are configured to have a second internal resonant frequency different than the first internal resonant frequency and matched to an external resonant frequency of an external circuit for communicating with the antenna implantable device, when the layer absorbs a fluid and causes a change from the first internal resonant frequency to the second internal resonant frequency after the therapy unit is implanted.
