Method of Energy Transfer to an Implantable Medical Device While Coupling Energy to Charging Unit

Abstract

External power source, charger, system and method for an implantable medical device having therapeutic componentry and a secondary coil operatively coupled to the therapeutic componentry. A primary charging coil is capable of transcutaneously inductively energizing the secondary coil when externally placed in proximity of the secondary coil. Drive circuitry is operatively coupled to the primary charging coil for exciting the primary charging coil. A rechargeable power source is operatively coupled to the drive circuitry. A secondary recharging coil is operatively coupled to the rechargeable power source. A primary recharging coil is adapted to be coupled to a source of AC power which when placed in proximity of the secondary recharging coil can inductively energize the secondary recharging coil in order to charge the rechargeable power source.
