METHOD OF MANUFACTURING A MEDICAL DEVICE HAVING A FEEDTHROUGH

摘要

A method of manufacturing an implantable medical device includes manufacturing a hermetic feedthrough by providing a first sheet of unfired ceramic material, forming one or more holes through the sheet, inserting a first conductive material into one of the holes, and forming a pad in electrical contact with the first conductive material in one of the holes, wherein the pad comprises a plurality of layers and has a thickness of at least 50 micrometers, at least one layer comprising a second conductive material having a different composition than the first conductive material. The method further includes co-firing the unfired ceramic material, the first conductive material, and the second conductive material. The method further includes coupling the feedthrough to an encasement structure of the implantable medical device.
