Abstract
First and second members spaced from each other are hermetically sealed by fused insulating materials. The insulating materials are partially amorphous and partially crystalline. The insulating materials have substantially identical characteristics. However, a first one of the insulating materials is more crystalline than a second one of the insulating materials. A third insulating material may also be included and may be more crystalline than the first insulating material. The first, second and third crystalline materials may have substantially identical compositions. The second insulating material may have nonwetting characteristics relative to the second member. This causes the second insulating member to have a domed configuration to increase the length of the dielectric leakage path. The third insulating material may be spaced from the second insulating material and may be provided with a flat surface to receive other members in abutting relationship. The first and second members and the insulating materials may be disposed on a lid in a heart pacemaker. The first member may be a terminal pin made from a noble metal and the second member may be a ferrule made from titanium or …
