Adjustable Pressure Hydrocephalus Shunt Valve

MIETHKE proGAV® 2.0

Hydrocephalus treatment involves the use of an adjustable valve with a gravitational unit.input:
output:MIETHKE gravitational valves offer a dependable solution for the prevention of overdrainage complications [1, 2] that are associated with the management of hydrocephalus.

proGAV® 2.0 is the most recent advancement in our existing proGAV® technology, which has been refined to more effectively meet the needs of our customers and their patients.

With the addition of a new tactile "Feedback" mechanism and "Soft-Touch" instrumentation, proGAV® 2.0 maintains the same level of reliability as our current technology.

The special valve surface of the adjustable unit is designed to release the "Active-Lock" mechanism of the valve and provide tactile feedback when slight pressure is applied with the finger.input:
