Passive charge of implantable medical device utilizing external power source and method
First Claim
1. An external power source for an implantable medical device implanted in a patient, said implantable medical device having a secondary coil operatively coupled to therapeutic componentry, comprising:
- a power source;
a modulation circuit operatively coupled to said power source;
an article into which said patient may come into proximity;
a plurality of primary coils operatively coupled to said modulation circuit and physically associated with said article;
said modulation circuit driving at least one of said plurality of primary coils; and
a sensor coupled to modulation circuit and adapted to sense proximity of a component related to said implantable medical device;
wherein said modulation circuit commences operation to drive at least one of said plurality of primary coils when said sensor senses proximity with said component related to said implantable medical device.

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.
