Abstract:
Apparatus for interacting with electrically excitable tissue of a patient comprising:a group of implantable electrodes adapted to interact with said tissue, said group of electrodes being arranged on at least one implantable lead to form at least one array wherein each electrode is adjacent at least one other of said electrodes;a main cable having at least one power conductor adapted to extend to a site adjacent said tissue wherein the number of said power conductors is fewer than the number of said electrodes;a source of data;a data conductor adapted to extend to said site adjacent said tissue from said source of data; andimplantable controller means in communication with said source of data and responsive to said data for gating to said main cable at least one pair of nonadjacent electrodes within said group to establish an anode and cathode relationship between said pair of nonadjacent electrodes.
