  • Filtered feedthrough assembly for implantable medical device
    Patent number: 5735884
    Abstract: A feedthrough configuration for a hermetically sealed implantable medical device which includes a metal case having an aperture and a feedthrough in the aperture which includes an electrically conductive pin, an insulating material supporting the pin, a block spaced from the case and in electrical continuity with the pin and a device for electrical protection connected to the block and to the case. The device for electrical protection preferably includes two zener diodes, a first diode connected at the block and a second diode connected to the case with an electrical conductor connecting the two diodes in a back-to-back configuration.
