Method and Apparatus for Implantable Lead
First Claim
1. A method for use with a first implantable lead, the first lead having a length and having at least first, second, and third satellites along its length, each satellite having at least one electrode, each satellite having a chip, the first lead having at least one conductor communicatively coupled with the chip of each satellite and extending to an end of the first lead, the at least one conductor connected to a respective connector at the end of the first lead, the method comprising the steps of:
- transmitting a control signal through the connector of the first lead and along the at least one conductor to the chips of the at least first, second, and third satellites, thereby configuring at each chip a respective impedance between the at least one conductor and the respective at least one electrode;
passing a pacing current 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.

Abstract
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.
