ABSTRACT:
A physiological shunt system for draining fluid from one region of the human body and discharging it into another in which means is included to resist overdrainage or siphoning of the region as a consequence of low downstream pressures, and a valve to provide such means. The system includes a collector catheter and a discharge catheter, and the valve interconnects these catheters to open the system to flow, or to close it to flow, as a consequence of the position of its closure means which is responsive to the pressure differential between the pressure in the valve as transmitted by the catheters, and a reference pressure such as the atmosphere.
