Patent ID: 8521304

Claim:
An implantable lead, comprising: a lead connector; an electrode configured to perform at least one of a sensing operation and delivery of electrical energy; a lead body having a proximal end portion and a distal end portion, the connector located at the proximal end, the electrode located at the distal end, the lead body having a length that includes a lumen that extends longitudinally between the distal and proximal end portions; a coil conductor having spiral sections that are wound within the lumen and extending from the lead connector along the lumen, the coil conductor coupling the lead connector to the electrode, the coil conductor having an insulation material provided on at least a segment of the coil conductor, the insulation material having a dielectric constant set to at least 5 and up to 100 such that the coil conductor forms a distributed band stop filter when exposed to a known RF magnetic field.
