First Claim
Patent Images
1. A high voltage charge storage array for an implantable device comprising:
- an array of at least about fifty low voltage battery cells; and
switching means electrically connected to each battery cell for selectively discharging the battery cells in series to produce a high voltage output to be delivered by the implantable device that is at least an order of magnitude greater than an output voltage of the low voltage battery cells.
