摘要： According to one embodiment, a feedthrough includes a sheet having a hole, where the sheet includes a first material that is a ceramic comprising alumina. The feedthrough further includes a second material substantially filling the hole. The second material is different than the first material and includes platinum and an additive that includes alumina. The first and second materials have a co-fired bond therebetween that hermetically seals the hole. According to another embodiment, a hermetic feedthrough for an implantable medical device includes a sheet having a hole, where the sheet includes a ceramic comprising alumina. The feedthrough also includes a second material substantially filling the hole, where the second material includes a platinum powder mixture and an alumina additive. The platinum powder mixture includes a first platinum powder having a median particle size of between approximately 3 and 10 micrometers and a second platinum powder that is coarser than the first platinum powder and has a median particle size of between approximately 5 and 20 micrometers. The platinum powder mixture includes between approximately 50 and 80 percent by weight of the first platinum powder and between approximately 20 and 50 percent by weight of the second platinum powder. The first and second materials have a co-fired bond therebetween that hermetically seals the hole.

摘要： A hermetic feedthrough for an implantable medical device includes an insulator, a conduit integrated with the insulator, and a pad coupled to an exterior surface of the insulator. The insulator includes a first material and the conduit includes a second material that is electrically conductive. The pad is configured to receive a lead coupled thereto. Further, the pad is electrically conductive and coupled to the conduit. The pad includes a first layer and a second layer overlaying at least a portion of the first layer.

摘要： A hermetic feedthrough for an implantable medical device includes an insulator, a conduit configured to conduct electricity through the insulator, and a ferrule coupled to the insulator. The insulator is formed from a ceramic material and the conduit and insulator have a co-fired bond therebetween, which hermetically seals the conduit with the insulator. The insulator is elongate and has opposing ends that include flat surfaces and the ferrule includes a frame for receiving the insulator.
