Abstract
The implantable device includes a power supply including a high value, small sized capacitor having at least a capacitive rating of 0.1 farads which is completely contained within the implantable device. This high value, small size capacitor or series of capacitors enables the implantable device to deliver, on a controlled and continual basis, electric energy over at least an eight hour period. Further, the capacitive power source is replenished via an external, RF coupled device on a daily or other long term periodic basis. During the replenishing cycle, the energy contained in the battery of the external transmitter is transferred to the internal capacitive power source in the implantable device. The method includes providing, on an exclusive basis, power to an implantable device via a high value capacitive source during at least an eight hour cycle of substantially continual delivery of electric energy. The method includes incorporating and containing a capacitive device in the implantable device wherein the capacitive device has a capacitive rating of at least 0.1 farads. The capacitive device captures and stores a pre-determined amount of coulombs of electrical energy. This el…
