Medical device packaging systems including electrical interfaces

An electrical interface includes a contact surface and a connector structure supporting the contact surface for electrical coupling with an electrical contact of a medical device, which device is contained within a package. The electrical interface facilitates coupling of the electrical contact of the packaged medical device to an electrical contact of another medical device, which is located outside the package. If the electrical contact of the packaged device is mounted within a bore of the device, then the connector structure allows for passage of a sterilizing gas into the connector bore, and past the connector contact, within the bore.
