Abstract:
1. An implantable medical lead comprising: a conducting electrode comprising: a conductive polymer connected to provide an electrically conductive path from the proximal end to the distal end; an insulating sheath surrounding the conductive polymer to electrically insulate a surface of the conductive polymer; a second conducting electrode comprising a second conductive polymer positioned along the insulating sheath; a second insulating sheath surrounding the second conductive polymer to electrically insulate a surface of the second conductive polymer, wherein either: (a) the conductive polymer penetrates the insulating sheath to a depth that is equal to or less than the wall thickness of the insulating sheath; (b) the conductive polymer penetrates a length equal to or less than a total length of the insulating sheath; or (c) the conductive polymer penetrates a surface area equal to or less than a total surface area of the insulating sheath.
