  • Glass-to-metal feedthrough seals having improved durability particularly under AC or DC bias
    Publication number: 20060247714
    Abstract: A hermetic implantable medical device (IMD) is provided with a single or multi-pin arrangement including selected glass to metal seals for a feedthrough including a ceramic disk member coupled to the sealing glass surface in potential contact with body fluids. By judicious selection of component materials (ferrule, seal insulator and pin) provides for either compression or match seals for electrical feedthroughs (having a single or multi-pin array) provide corrosion resistance and biocompatibility required in IMDs. The resultant feedthrough configuration accommodates one pin within a single ferrule or at least two pins in a single ferrule having a pin surrounded by insulator material (e.g.
