ABSTRACT:
Implanted medical devices such as heart assist devices powered by electric motors or solenoids require a high amount of power compared to other electric implants such as pacemakers which do not use motors. A percutaneous power transmission system for use with implanted motors includes a skull-mounted post and a highly flexible array of wires implanted in a serpentine configuration to enhance flex life and prevent failure due to excessive longitudinal tension. In the preferred embodiment, a cable passed across the neck in zig-zag fashion includes a separable implanted connector removably attachable within a post fixed by bone screws and a flange to the skull. The implanted connector is passed through smaller incisions and a smaller subcutaneous tunnel then would be required to fit the flange. This reduces surgical trauma, and facilitates healing without infection and with minimal scarring on the neck.
