Device for supplying energy to hydraulically or pneumatically actuated active implants

A device for supplying energy to a hydraulically or pneumatically actuated active implant, wherein hydraulic or pneumatic actuation of the active implant is effected via a transmitter fluid, and wherein the device comprises:

• a receiving coil for generating an electric voltage caused by a changing magnetic flux generated by an extracorporeal transmitter coil, the receiving coil being designed such that it is adapted for implantation in subcutaneous tissue,
• an electric line for transmitting electric current generated by the receiving coil from the receiving coil to the active implant, and
• a compensation container for temporarily storing the transmitter fluid via which the active implant is actuated,
• wherein the compensation container is arranged at the receiving coil and/or at the electric line such that the compensation container is adapted to be implanted, together with the receiving coil and/or the electric line, in a common tissue or muscle pocket in a patient's body,
• wherein the compensation container and the receiving coil are arranged in an incompressible housing, wherein the incompressible housing is filled with a medium for adjusting compliance of an outer wall of the compensation container, wherein the medium surrounds the compensation container, and
• wherein the compliance is adjustable independently of wall tension of the compensation container by changing a volume, a density and/or a compressibility of the medium in the incompressible housing.
