Abstract: A method of interconnecting a conductor and a hermetic feedthrough of an implantable medical device includes welding a lead to a pad on a feedthrough. The feedthrough includes a ceramic insulator and a via hermetically bonded to the insulator. The via includes platinum. The pad is bonded to the insulator and electrically connected to the via, includes platinum, and has a thickness of at least 50 μm. The lead includes at least one of niobium, platinum, titanium, tantalum, palladium, gold, nickel, tungsten, and oxides and alloys thereof.

Abstract: An implantable medical leads has a conductor that includes one or more metal wires and one or more carbon nanotube wires extending in substantially the same direction as the one or more metal wires. Such conductors may result in less MRI-induced heating at electrodes of leads than conductors that do not contain carbon nanotubes.
