Integra™ Flow Regulating Valves helps in minimizing the potential risks related with both postural and vasogenic overdrainage. They are the only hydrocephalic shunt valves that use variable resistance to flow to make sure that the flow of cerebrospinal fluid (CSF) is maintained at a physiologic rate of production. A close balance between CSF production and drainage rate is provided by Integra's unique flow regulating technology. Also, by reducing the size of the valve opening as pressure increases Integra Flow Regulating Valves are able to move from a valve with a low opening pressure to one with a higher pressure. As a result of regulating the CSF flow rate in response to differential pressure, the valve ensures that CSF flow does not attain an excessive rate. Therefore, it limits the risks associated with overdrainage and the size of the ventricles is gradually reduced. Flow Regulating Valves are considered as Magnetic Resonance which are safe in accordance with ASTM F203 and it address the patient's changing pressure needs without manual adjustments.
