ABSTRACT:
A body implantable medical infusion system including an infusate reservoir, a system for regulating infusate discharge and a catheter for delivery of discharged infusate to the desired infusion site. An unregulated infusate discharge is prevented, in a preferred embodiment, by a normally open valve positioned intermediate the pump and the catheter, the valve closing in response to the sensing of unregulated infusate. A sensor, to which the valve responds, may be positioned at the output of the pump or at any other location within the system to sense infusate leakage. The valve may be additionally closed in response to an externally generated signal.
