    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: A hermetic feedthrough for an implantable medical device includes an insulator body and a ferrule. The insulator body includes ceramic material and one or more electrically conductive conduits extending through the insulator body. The insulator is disposed in an opening of the ferrule. The insulator body includes a plurality of substantially flat surfaces that each include a plurality of edges. A rounded corner extends between adjacent edges of any two adjacent substantially flat surfaces. Each corner between any two adjacent substantially flat surfaces that face toward the ferrule has an average radius that is less than approximately 25% of a length of the corresponding edges.

    Abstract: A method of manufacturing an implantable medical device includes manufacturing a hermetic feedthrough by providing a first sheet of unfired ceramic material, forming one or more holes through the sheet, inserting a first conductive material into one of the holes, and forming a pad in electrical contact with the first conductive material in one of the holes, wherein the pad comprises a plurality of layers and has a thickness of at least 50 micrometers, at least one layer comprising a second conductive material having a different composition than the first conductive material. The method further includes co-firing the unfired ceramic material, the first conductive material, and the second conductive material. The method further includes coupling the feedthrough to an encasement structure of the implantable medical device.
