An apparatus for filling a device having a penetrable septum and a sealed chamber. The apparatus includes a filling member engageable with the penetrable septum to penetrate the septum, port(s), and a closure. The closure and filling member are movable between (i) a first position wherein the closure closes the port(s), and (ii) a second position opening the port(s). The filling member and/or septum is movable relative to the other between (i) a first position wherein the filling member is spaced from the septum, and (ii) a second position wherein the filling member is penetrated through the septum and in communication with the sealed chamber. A locking device is movable between (i) a locked position locking the closure and/or filling member in the first position, and (ii) an unlocked position allowing movement of the closure and/or filling member relative to the other and into the second position.
