Integra® Flow Regulating Valves
Integra® Flow Regulating Valves are the only hydrocephalic shunt valves that use variable resistance to flow to ensure that the flow of cerebrospinal fluid (CSF) is maintained at a physiologic rate of production, thus minimizing the potential risks associated with both postural and vasogenic overdrainage.
Integra's unique flow regulating technology provides a close balance between CSF production and drainage rate. Integra Flow Regulating Valves are able to transition from a valve with a low opening pressure to one with a higher pressure by reducing the size of the valve opening as pressure increases.
By adjusting the CSF flow rate in response to differential pressure, the valve ensures that CSF flow does not reach an excessive rate. Thus the size of the ventricles is gradually reduced and limits the risks associated with overdrainage.
