Abstract
An implantable lead includes a lead body and at least one safety element. The lead body has a distal end and a proximal end. The lead body defines at least one lumen extending along at least a portion of the lead body. The lead body includes a plurality of electrodes disposed on the distal end of the lead body, a plurality of terminals disposed on the proximal end of the lead body, and a plurality of conductors disposed in the lead body, each conductor electrically coupling at least one of the electrodes to at least one of the terminals. The at least one safety element is disposed along at least a portion of the lead body and is configured and arranged to reduce damage to patient tissue adjacent to the plurality of electrodes due to heating, induced electrical signals, or both when the lead is exposed to radio frequency irradiation.
