Abstract
A medical electrical electrode includes an elongated conductive coil located over a lead body, and a conductive polymer material in contact with the lead body and located between individual coils of the elongated conductive coil. In certain embodiments, the conductive polymer is a polymer (e.g., silicone) implanted with a conductive filler (e.g., carbon black). In certain embodiments, the conductive polymer material is generally isodiametric with an outer diameter of the individual coils of the elongated conductive coil. A medical electrical electrode is fabricated by sliding an elongated conductive coil over a length of a lead body, dispersing a conductive polymer on the helical coil, inserting a tubing over the elongated conductive coil, distributing the polymer material between individual turns of the elongated conductive coil, heating the tubing so the tubing shrinks around the elongated conductive coil, and removing the tubing.
