Abstract

A stimulation lead to be implanted into a patient's body includes at least one distal stimulation electrode and at least one conductive filer electrically coupled to the distal stimulation electrode. A jacket houses the conductive filer and provides a path distributed along at least a portion of the length of the lead for conducting induced RF energy from the filer to the patient's body.
