1. A medical implant apparatus for a patient, comprising:

  • an energy transmission means for wireless transmission of energy of a first form from outside the patient'"'"'s body;

    an implantable medical device operable in response to energy of a second form; and

    an implantable energy transforming means for transforming the energy of the first form wirelessly transmitted by the energy transmission means into energy of the second form, which is used for operating the medical device,wherein the energy transforming means comprises at least one element having a positive region and a negative region and adapted to create an energy field between said positive and negative region when exposed to wireless energy of the first form transmitted by the energy transmission means, so that the energy field produces energy of the second form, wherein the element comprises an electrical semi-conductor junction element capable of inducing an electric field between the positive and negative regions when exposed to energy of the first form transmitted by the energy transmission means,wherein the electrical semi-conductor junction element comprises a flat sheet, and wherein the electrical semi-conductor junction element is adapted to generate an electrical current whereby the energy of the second form comprises electric energy, wherein the medical device is electrically operated, and the positive and negative regions of the electrical semi-conductor junction element supply electric energy for the operation of the medical device, the medical implant further comprising an implantable motor, pump or motor and pump operably connected to the medical device, wherein the element is adapted to power the implantable motor, pump or motor and pump with energy of the second form, by at least one of;

    directly operating, with the energy of the second form as the energy transmission means transmits energy of the first form, andstoring energy in a comprised implantable energy storage device being an electric accumulator, the electric accumulator comprising at least one capacitor or battery for storing energy of the second form for indirect supply of energy.
