Abstract
An implantable medication dispensing system includes an integral reservoir from which medicament is dispensed by a manually actuated micro-infusion pump system. Medicament is added to and removed from the reservoir as required through a liquid-sealed fill port having a integral needle-actuated safety valve. Upon introduction of the needle through a self-sealing septum, the safety valve is actuated open to allow medicament to be introduced and withdrawn by the needle. Upon removal of the needle the septum is closed by radial compression and the safety valve is actuated closed to prevent pressure flow through the fill port.
