CO-FIRED HERMETICALLY SEALED FEEDTHROUGH WITH ALUMINA SUBSTRATE AND PLATINUM FILLED VIA FOR AN ACTIVE IMPLANTABLE MEDICAL DEVICE |
摘要 |
A co-fired hermetically sealed feedthrough is attachable to an active implantable medical device. The feedthrough comprises an alumina dielectric substrate comprising at least 96 or 99% alumina. A via hole is disposed through the alumina dielectric substrate from a body fluid side to a device side. A substantially closed pore, fritless and substantially pure platinum fill is disposed within the via hole forming a platinum filled via electrically conductive between the body fluid side and the device side. A hermetic seal is between the platinum fill and the alumina dielectric substrate, wherein the hermetic seal comprises a tortuous and mutually conformal interface between the alumina dielectric substrate and the platinum fill. |
