Abstract

Overdrainage from siphoning, a result of negative distal pressure, has been a major problem with the existing differential pressure shunt devices. The antisiphon/siphon control devices used to reduce siphoning often malfunction owing to fibrous scar formation around the valve. Similarly, the functioning of gravity-actuated systems is adversely affected by body movements. Constant flow shunt systems may not be superior to existing differential pressure valves,as has been shown in a recent multicenter study. In view of these difficulties, we investigated the possibility of developing a shunt valve based on the Starling resistor concept of flow regulation that allows proximal pressure-dependent and distal pressure-independent flow. The valve designed is capable of proximal pressure-dependent and distal pressure-independent flow. The valve allows for adjustable negative pressure in the vertical position.
