Abstract
An implantable stimulation lead includes a lead body having a proximal end and a distal end; a plurality of electrodes disposed along the distal end of the lead body; a plurality of terminals disposed along the proximal end of the lead body, and a plurality of conductors disposed in the lead body and including a first conductor and a second conductor. Each conductor electrically couples at least one of the electrodes to at least one of the terminals. The first conductor has a RF impedance that is at least 25% greater in magnitude than the second conductor.
