DIRECT INTEGRATION OF FEEDTHROUGH TO IMPLANTABLE MEDICAL DEVICE HOUSING USING A GOLD ALLOY |
摘要 |
One aspect provides a method of attaching a feedthrough to a titanium housing of an implantable medical device. The method includes providing the housing with a flange forming a recess about an opening through the housing, the opening disposed within the recess. A feedthrough is positioned within the recess so as to form a gap between the flange and an insulator of the feedthrough. A braze preform is then positioned within the recess about the insulator, the braze preform comprising a biocompatible braze material having a melting point less than a β-transus temperature of the titanium of the housing. The preform is melted at a temperature less than the β-transus temperature of the titanium of the housing such that the melted braze material fills at least the gap, and then cooled to form a braze joint which bonds the insulator to the housing and hermetically seals the opening. |
