In one embodiment of the invention, an implantable lead is provided. It has a plurality of satellites along its length, each satellite having at least one electrode and having as many as four electrodes at each satellite. Each satellite has a chip which controls the manner in which electrodes are or are not connected with a conductor within the lead. In an embodiment a control signal is transmitted through the connector of the first and along the at least one conductor to the chips of the satellites, thereby configuring at each chip a respective impedance between the at least one conductor and the respective at least one electrode. Sub-sequently, a pacing current is passed through the connector of the first lead and along the at least one conductor, and at each chip passing a portion of the pacing current through the respective impedance to the respective at least one electrode. |
