1. A process for supplying an electrical energy converting implant with electrical energy comprising the steps of:
- (a) providing an electrical voltage source by generating electrical voltage by the linear movement of a piston 7 of a free-piston generator 2,wherein the free-piston generator 2 comprises a guide cylinder 6, in which a piston 7 with at least one permanent magnet is located, and at least one coil 8,the guide cylinder 6 is introduced into a blood vessel 1 and the at least one coil 8 is located outside the blood vessel 1,the piston 7 is being moved within the guide cylinder 6 of the free-piston engine 2 by the periodically pulsating blood in the blood vessel 1 linearly relative in the direction of the respective blood flow F, andas a function of this linear movement of the piston 7 an electrical voltage is induced in the at least one coil 8, and(b) withdrawal of electrical energy from the electrical voltage source of step (a) by the current control unit of the electrical energy converting implant.
