Patent ID: 8738154

Claim:
An implantable device for target site stimulation, the device comprising: a multiplexed lead comprising at least one conductor; a plurality of multiplexed addressable units secured at predetermined locations along the conductor, wherein each addressable unit comprises: a multi-port connector defining a plurality of ports, wherein each port receives an electrode lead that is electrically coupled to and secured to the multi-port connector and each electrode lead includes a plurality of independently excitable electrodes; and a plurality of independently addressable integrated circuits corresponding to the number of defined ports in the multi-port connector, wherein each circuit is electrically coupled to the corresponding electrode lead at the corresponding port and wherein each circuit controls the power flowing to each of the plurality of independently excitable electrodes of the respective electrode lead in the corresponding port; and a hermetically sealed control unit electrically coupled to one end of the conductor distal from the addressable units, wherein the control unit provides control information and power to each of the plurality of multiplexed addressable units through the conductor, wherein the multiplexed addressable units are arranged and multiplexed in a linear configuration.
