Device for supplying energy to hydraulically or pneumatically actuated active implants

摘要

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.

主权项

1. 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.
