Distributed implant systems

摘要

A distributed implantable neurostimulation system. One or more electrode arrays each have at least one electrode configured to be positioned at a desired implant location within the body. An implantable control unit is configured to selectively direct stimulus and/or telemetry instructions and power to each electrode of each array. A shared bus extends to each of the plurality of electrode arrays, the bus interconnecting each array with the implantable control unit. There is at least one electrode cell associated with each electrode array. The electrode cell obtains electrical power and command signals from the shared bus, and controls operation of each electrode associated with that electrode cell. The bus is connected to the control unit and/or the electrode cell by docking contacts of the bus to form electrical contact with contacts of the control unit and/or electrode cell.
