  • Drug administration device over full protection valve
    Patent number: 5158547
    Abstract: A technique for protecting an implantable drug administration device from damage caused by over filling. The protection is implemented using an automatic valve positioned between the puncturable sealing septum and the reservoir. This automatic valve is operated volumetrically by coupling the valve actuator to the diaphragm which separates the drug chamber from the fluid volume compensation chamber. When the diaphragm flexes to the maximum fill position, the valve actuator closes the automatic valve, thus prohibiting any further transfer to the reservoir.
