    摘要： A feedthrough assembly, as well as a method of forming a feedthrough assembly, including a metallic ferrule, and a biocompatible, non-conductive, high-temperature, co-fired insulator engaged with the metallic ferrule at an interface between the ferrule and the insulator. The insulator includes a first surface at the interface and a second surface internal to the insulator. At least one conductive member may be disposed at the second surface, wherein at least the first surface of the insulator is devoid of surface cracks greater than 30 μm. The first surface of the insulator may also be devoid of a surface roughness greater than 0.5 μm.

    摘要： A method for making a feedthrough assembly for an implantable electronic medical device comprises providing a metallic ferrule having an outer surface and an aperture defined by an inner lumen surface; providing an insulator, the insulator having a first surface and a second surface. At least one of the first surface and the second surface of the insulator includes a brazing region disposed thereon. The braze material is applied to the brazing region and the insulator is positioned within or around the metallic ferrule such that the positioned insulator brazing region and the metallic ferrule outer surface or inner lumen surface defines a braze gap. The braze gap has a width ranging between 10 μm to 50 μm. The feedthrough assembly is then heated at a temperature conducive to melt the braze material in the braze gap thereby forming a hermetic seal between the ferrule and said insulator.

    摘要： A titanium silicide material based on Ti.sub.5 Si.sub.3 intermetallic compound exhibits substantially improved oxidative stability at elevated temperatures. In particular, carbon is added to a Ti.sub.5 Si.sub.3 base material in an amount (e.g. about 0.3 to about 3.6 weight % C) effective to impart substantially improved oxidative stability at elevated temperatures, such as about 1000.degree. C. Boron is added to a Ti.sub.5 Si.sub.3 base material in an amount (e.g. about 0.3 to about 3.3 weight % B) to this same end.
