Medtronic PS Medical Pressure Differential Valves

The Medtronic PS Medical CSF-Flow Control valve is a pressure differential valve built to open at a set pressure.  In vivo, the pressure that the valve responds to is the difference between the intracranial pressure and the pressure of the space into which the distal end of the system is draining into (e.g., the intraperitoneal pressure).
