Attorney, Agent or FirmInternational ClassA61N 001/08AbstractMethods and apparatus for providing a sufficiently stable power to a load in an energy transfer system that transfers energy from one side of a physical boundary to another side of the boundary. In one example, a power supply and a primary winding are located on a first side of a physical boundary (e.g., external to a body), and a secondary winding and the load are located on a second side of the physical boundary (e.g., internal to the body). A primary voltage across the primary winding is regulated so as to provide a sufficiently stable output power to the load notwithstanding changes in the load and/or changes in a relative position of the primary winding and the secondary winding. One aspect of the invention relates to energy transfer methods and apparatus for use in connection with the human body. In particular, one example of the invention includes a transcutaneous energy transfer (TET) system for transferring power from a power supply external to the body to a device implanted in the body.Field of SearchElectrical therapeutic systemsParameter control in response to sensed physiological load on heart Communicating with pacer (e.g., telemetry) Energy source external of generator or body Energy source outside generator body Output controlled by sensor responsive to body or interface condition | |
