Abstract: In some examples, a feedthrough assembly for a medical device may include a ferrule. The ferrule defines an aperture extending through the ferrule from an outer end surface defined by the ferrule to an end inner end surface defined by the ferrule. The aperture includes a first portion having a first diameter and a second portion having a second diameter less than the first diameter. The aperture defines a longitudinal axis extending therethrough and the ferrule defines a ledge between the first and second portions of the aperture that extends radially inward toward the longitudinal axis. The feedthrough assembly further may include a conductive pin within the aperture and an insulating member surrounding at least a portion of the pin. The insulating member may electrically insulate the conductive pin from the ferrule, and the ledge and a surface of the insulating member adjacent the ledge may define a space therebetween.

Abstract: In some examples, a feedthrough assembly a ferrule including a base portion and at least one projection extending from the base portion; a capacitive filter positioned adjacent the base portion of the ferrule such that an outer wall of the capacitive filter faces an inner wall of the at least one projection of the ferrule; a conductive pin extending through an aperture in the ferrule and an aperture in the capacitive filter; and an electrically conductive material between the inner wall of the at least one projection of the ferrule and outer wall of the capacitive filter that electrically couples the ferrule and the capacitive filter to ground the capacitive filter, wherein the inner wall of the at least one projection of the ferrule and the outer wall of the capacitive filter are tapered.
