Abstract
An implantable electrical lead having a lead body with a longitudinal lumen therein and a stranded electrical conductor located in the lumen and which exits the lumen at a distal portion of the lead body, the distal end of the conductor being curved to form a loop and reentering the lumen, terminating within the lumen alongside a more proximal portion of the conductor. The portion of the conductor exterior to the lumen is wound around the lead body to form a coiled electrode. In some embodiments the distal end of the conductor is coupled to a more proximal portion of the conductor to form a loop and the loop is wound around the lead body to form a bifilar coil. In other embodiments the conductor is wound around the lead body to form a mono-filar coil. The distal end of the conductor is mechanically and electrically coupled to a more proximal portion of the conductor, within the lumen.
