Abstract
In a method and apparatus for forming a hermetically sealed bond for use in implantable medical devices, a first structure, made from a first material, is positioned against a second structure, made from a second material. A compressive force directed at the second structure is applied to the first structure, and an equal force directed at the first structure in a direction opposite the compressive force is applied to the second structure so that the first and second structures are isodynamically pressed together. The first and second structures are heated to a diffusion temperature whereat the first material and the second material undergo diffusion, thereby forming a hermetically sealed bond between the first and second materials.
