ABSTRACT:
A feedthrough configuration for a hermetically sealed implantable medical device includes a metal case having an aperture and a feedthrough in the aperture which includes a ferrule sealed in the aperture, a pin extending through the ferrule and the aperture, an insulating material supporting the pin within the ferrule and an electrically conductive block spaced from the ferrule and in electrical connection with the pin. A device for electrical or electromagnetic protection can be connected to a peripheral upstanding portion of the ferrule and a peripheral skirt portion of the block. This arrangement of feedthrough elements can be particularly useful if the protective device is a chip capacitor which typically has a flat-sided configuration that can bridge the space between the ferrule and the block and be connected at one end to the block and at the other end to the ferrule.
