Abstract

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