An apparatus having a foil pack defining a device enclosure and a fluid conduit defining a fluid channel. The device enclosure may be configured to hold an energy storage device such as a battery or capacitor. The fluid conduit defines a fluid channel configured to allow a flow from the device enclosure through a test port defined by the fluid conduit. The apparatus is configured to establish a vacuum in the device enclosure when a vacuum is established in the fluid channel (e.g., during leak testing of the device enclosure). A scaffolding within the fluid conduit is configured to configured to resist a collapse of the fluid channel when the vacuum is established in the fluid channel.

Foil pack

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.

Feedthrough assembly with feature for controlling component position

A feedthrough component includes a feedthrough ferrule including a ferrule body extending from a proximal end to a distal end along a longitudinal axis of the feedthrough ferrule and a ferrule passageway extending through the ferrule body and defined by a plurality of sidewalls. The ferrule passageway includes a proximal passage portion defined by one or more proximal sidewalls of the plurality of sidewalls and extending along the longitudinal axis, a distal passage portion defined by one or more distal sidewalls and extending along the longitudinal axis, and a beveled ledge disposed between the proximal passage portion and the distal passage portion and extending from the one or more distal sidewalls toward the longitudinal axis of the feedthrough ferrule. The beveled ledge includes a beveled surface extending toward the longitudinal axis, where a normal to the beveled surface intersects the longitudinal axis.
