Adjustable valve with gravitational unit for the treatment of hydrocephalus

MIETHKE gravitational valves provide a reliable solution in prevention of overdrainage complications [1, 2] associated with the management of hydrocephalus.
proGAV® 2.0 represents the latest development by refining our existing proGAV® technology to better meet the needs of our customers and their patients.
proGAV® 2.0 offers the reliability of our existing technology with a new tactile “Feedback” mechanism and “Soft-Touch” instrumentation. 
The adjustable unit is equipped with a special valve surface: By using slight pressure with your finger, the “Active-Lock” mechanism of the valve is released and a tactile feedback is received.
The combination of the refined proGAV® technology and “Soft-Touch” instrumentation provides comfort for patients and security against inadvertent readjustment caused by magnetic fields up to 3 Tesla [3].
With the new proGAV® 2.0 Compass the opening pressure of the adjustable unit can be identified quickly, without having to expose the patient to X-ray.

Advantages

  • 3-tesla MRI Conditional
  • Pressure levels for continuous adjustment between 0 and 20 cmH2O
  • X-ray-free verification of opening pressure setting
  • Tactile feedback
  • Soft and secure adjustment by “Soft-Touch” Adjustment and Measurement Tools

Note

The MIETHKE proGAV® 2.0 is available as a single valve or as a shunt system with different components.

Indication

  • Treatment of Hydrocephalus
