Abstract
The implantable stimulator in accordance with the principles of the present invention utilizes a high value, small sized capacitor having at least a capacitive rating of 0.1 farads which is completely contained within the implantable stimulator. This high value, small size capacitor or series of capacitors enables the implantable stimulator to deliver, on a controlled and continual basis, electric stimulation pulses to targeted tissues over at least a 8 period. Further, the capacitive power source is recharged or replenished via an external, RF coupled device on a daily or other long term periodic basis. The method includes providing, on an exclusive basis, power to an implantable stimulator via a high value capacitive source during at least a twenty-four cycle of substantially continual delivery of electric stimulation pulses to targeted tissue. The method includes incorporating and containing a capacitive device in the implantable stimulator 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 electrical energy is utilized to power the implantable stim…
