    摘要： An optical window assembly for use in implantable medical devices includes a generally U-shaped ferrule having a strain relief channel to accommodate residual stresses remaining in the ferrule after welding the ferrule to the housing of an implantable medical device. The assembly may be used to transmit optical energy and/or electrically insulate a feedthrough. The assembly can be mounted in a window opening in a housing. The ferrule can include a ferrule body forming a lens opening, the ferrule body having a generally U-shaped cross-section with an inner leg, an outer leg, and a strain relief channel in the ferrule body between the inner leg and the outer leg. A lens is mounted in the lens opening of the ferrule. The ferrule can also include a lens flange on the inner leg of the ferrule body, a support flange on the outer leg of the ferrule body, and/or a braze stop to control flow of the braze. The ferrule and housing can be constructed of titanium. Also disclosed are methods of manufacturing the optical window assemblies and implantable medical devices including the optical window assemblies.

    摘要： Implantable medical devices (IMDs) and their various components, including flat electrolytic capacitors for same, and methods of making and using same and providing for outgassing of gases released during capacitor charge and discharge cycles are disclosed. A gas vent and liquid electrolyte barrier into the electrolyte fill tube lumen that is used to fill the interior case chamber with electrolyte and then needs to be closed to prevent leakage of electrolyte. The fill port is shaped to comprise a fill port tube having interior and exterior tube ends and a fill port ferrule intermediate the ends of the fill port tube and comprising a fill port ferrule flange extending transversely to and away from the fill port tube. The fill port ferrule is mounted in an opening disposed in one of the case wall and the cover wall with the ferrule flange in sealing engagement therewith to locate the exterior tube end extending outwardly away from the fill port ferrule flange and the interior tube end within the interior case chamber. A microporous plug is injected into and fills the fill port lumen, the plug formed of a microporous material allowing the escape of gas released from the liquid electrolyte during capacitor charging while preventing escape of liquid or vaporized electrolyte.

    摘要： A feed-through assembly for an IMD and a method for fabricating the same are provided. The feed-through assembly has a ferrule having a first aperture disposed therethrough. An insulating member is disposed at least partially within the first aperture. The insulating member has a second aperture, an inside surface and an outside surface. A metallization region overlies at least a portion of the inside surface and at least a portion of the outside surface of the insulating member. The metallization region is formed of a first layer of titanium and a second layer of niobium. A portion of a terminal pin of platinum is disposed through the second aperture. A first brazing seal is disposed between the insulating member and the ferrule and a second brazing seal is disposed between the insulating member and the terminal pin. The first and second brazing seals are formed of gold.
