Abstract:
1. A filtering capacitor feedthrough assembly for an implantable active medical device comprising: an electrically conductive feedthrough ferrule or housing of an implantable active medical device a capacitor having an aperture defined by an inner capacitor surface, the capacitor electrically grounded to the electrically conductive feedthrough ferrule or housing of the implantable active medical device; a terminal pin extending into the aperture; and an electrically conductive split ring sleeve disposed within the aperture and between the terminal pin and the capacitor, the split ring sleeve includes a first end, a second end, a sleeve length therebetween, and a longitudinal slit though the sleeve extends from the first end to the second end, the electrically conductive split ring sleeve mechanically securing and electrically coupling the terminal pin to the capacitor and the split ring sleeve first end has a circumference that is greater than the second end; wherein the split ring sleeve comprises two or more metallic layers.
