1. A system for delivering, in a controlled manner, one or more electric stimulation pulses to targeted tissue comprising:

  • an implantable stimulator, said stimulator capable of delivering, in a controlled manner, one or more electric stimulation pulses to targeted tissue;

    a power source, contained within said implantable stimulator, sufficient to supply power to said implantable stimulator on an exclusive basis over at least an 8 hour period, said power source including a high value, small size capacitive energy storage unit having a capacitive rating of at least 0.1 farads; and

    an inductor coil adapted to gather emf power transmissions, a rectifier and a voltage regulator, all electrically coupled to said capacitive energy storage unit and incorporated into said implantable stimulator, for supplying replenishing current to said capacitive energy storage unit.
