Patent ID: 8620453

Claim:
A medical lead for use in an implantable neurostimulation system of the type which includes a neurostimulator for generating electrical stimulation therapy, the lead comprising: an implantable elongate insulating body; a connector on a proximal end of the insulating body configured to be electrically coupled to the neurostimulator; a distal electrode on a distal end of the insulating body; and at least one filer within said insulating body, said filer having a DC resistance in the range of 375-2000 ohms and having a proximal end being electrically coupled to the connector, the filer being helically coiled relative to the insulating body along the length of the insulating body, the helical coil of the filer extending uninterrupted with a same diameter and same number of turns per unit of length from the connector to the distal electrode, and the helical coil of the filer creating an inductance that is distributed along the length of the insulating body.
