ABSTRACT:
An implantable electrical lead having an elongated insulative lead body with a longitudinal lumen therein extending from the proximal end of the lead body to a distal portion of the lead body and having an elongated stranded electrical conductor located in the lumen, the conductor having a distal end which exits the lumen at the distal portion of the lead body and which is curved to form a loop exterior to the distal portion of the lead body and which then re-enters the lead body. In some embodiments, the strands of the conductor are twisted helically in a first direction and the conductor is twisted in a second, opposite direction in that portion of the conductor located exterior to the lead body to separate strands of the conductor. The stranded conductor may exit the lumen at the distal end of the lead body or at one or more locations proximal to the distal end of the lead body.
