Claim Text:
1. An RF/MRI compatible lead having a proximal end and a distal end, the lead comprising: an outer layer of a biocompatible, non-conductive polymer material extending along a portion of the lead; at least one electrode disposed along the distal end of the lead; at least one insulated conductor extending along the lead and electrically coupled to the at least one electrode, each of the at least one insulated conductor having a length with opposing distal and proximal end portions, each of the at least one insulated conductor having at least one segment with a multi-layer coil configuration, each multi-layer coil configuration being covered by the outer layer of the biocompatible, non-conductive polymer material and being formed from a single one of the at least one insulated conductor and comprising a first forward coiled section that extends in a forward lengthwise direction for a first forward physical length, then turns to merge into a proximately positioned reverse coiled section that extends in a substantially opposing reverse lengthwise direction for a reverse physical length, then turns to merge into a proximately positioned second forward coiled section that extends in the forward lengthwise direction for a second forward physical length, wherein the first forward coiled section, reverse coiled section, and second forward coiled section of the multi-layer coil configuration are each part of the single one of the at least one insulated conductor, wherein the lead is flexible and is configured and arranged for insertion into a body of a patient.
