Abstract

A device for supplying energy to hydraulically or pneumatically actuated active implants. The device can take the form of pumping systems, metering systems, and/or occlusion systems. The device comprises a receiving coil for generating an electric voltage due to a changing magnetic flux that is generated by an extracorporeal transmitting coil. The receiving coil is designed such that said coil can be implanted into subcutaneous tissue. Furthermore, an electric line is provided for transmitting the electric current that is generated by the receiving coil from the receiving coil to the active implant. The device further comprises a compensation container for temporarily receiving a transmitter fluid, by means of which the active implant is activated. The compensating container is mounted on the receiving coil and/or on the electric line such that the compensating container together with the receiving coil and/or the electric line can be implanted into a common tissue or muscle pocket in the body of a patient.
