Abstract

Disclosed herein is system and method for generating, storing and transmitting electrical charge from heart'"'"'s electrical conduction system to power implantable medical devices. An intelligent monitoring module in the system monitors amount of nerve impulses that are generated at the Sinoatrial (SA) node of the heart and continuously compares number of the generated nerve impulses with a threshold nerve impulse value. If excess impulses are detected, the intelligent monitoring module routes the excess nerve impulses to a battery management module which generates charge by converting the excess nerve impulses to electric charge. This charge may be further used to power up the implantable medical device.

Claims
