A hybrid battery power source for implantable medical use provides a generally constant low internal resistance during discharge and avoids voltage delays of the type that develop as a result of run down-induced resistance increase in Li/SVO cells. The hybrid battery power source utilizes two batteries or cells, one being a primary cell of relatively high energy density and the other being a secondary cell of relatively low internal resistance that is rechargeable. The primary and secondary cells are connected in a parallel arrangement via a voltage boos...
What is claimed is: 1. A hybrid battery power source for implantable medical use, comprising: a primary battery; a secondary battery connected to receive power from said primary battery; said secondary battery being adapted to power to an implantable medical device designed for high energy electrical stimulation of body tissue for therapeutic purposes; and a charge control circuit powered by said primary battery and including voltage reference and window comparator means for charging said secondary battery while limiting charge/discharge excursions ther...
