Medtronic PS Medical Delta Valves

The Medtronic Delta® valves is a siphon control device that resists siphoning of CSF from the brain’s ventricular system.  The valve is designed to be closed at its resting state and to not allow CSF to flow through it down a pressure gradient due to the shunt’s outlet being below its inlets.  Only when pressure builds proximal to the valve to a value in excess of the it’s opening presssure will the valve open to allow flow of CSF through the shunt.
