Abstract

An implantable stimulation system comprises a stimulator (138) for generating electrical stimulation and a conductive stimulation lead (134) having a proximal end electrically coupled to the stimulator (138), wherein at least a first component of the impedance looking into the stimulator (138) is substantially matched to the impedance of the stimulation lead (134). At least one distal stimulation electrode (132) is positioned proximate the distal end of the stimulation lead (134).
