Abstract
External power source for an implantable medical device implanted in a patient, the implantable medical device having a secondary coil operatively coupled to therapeutic componentry and method therefore. A modulation circuit is operatively coupled to a power source. A plurality of primary coils are operatively coupled to the modulation circuitry and physically associated with an article into which the patient may come into proximity. The modulation circuit drives at least one of the plurality of primary coils. A sensor is coupled to modulation circuit and is adapted to sense proximity of a component related to the implantable medical device. The modulation circuit commences operation to drive at least one of the plurality of primary coils when the sensor senses proximity with the component related to the implantable medical device.
