Abstract

One aspect is a feedthrough for a medical implantable device including a ferrule having a metal that is configured to be welded to a case of the implantable device. The ferrule substantially surrounds an insulator and shares an interface therewith, the insulator having a glass or ceramic material. Conductive elements are formed through the insulator providing an electrically conductive path through the insulator. There is no braze or solder at the interface between the ferrule and the insulator and that there is no braze or solder adjacent the conductive elements.
