Unique self adjusting gravitational valve for the treatment of adult hydrocephalus

The MIETHKE GAV® is a unique gravitational valve for the treatment of adult hydrocephalus. It automatically varies its opening pressure as soon as this becomes necessary due to alterations in the patient’s body position. Thus it effectively prevents symptoms of overdrainage. Thanks to the physiological drainage and its variable concept, the MIETHKE GAV® is well suited for the treatment of NPH patients, as well as for extreme forms of hydrocephalus in adults.
The MIETHKE GAV® is made from titanium, a material that guarantees outstanding precision, reliability and biocompatibility.


  • Automatic adjustment of opening pressure
  • Effective protection against overdrainage
  • MRI compatible
  • Very slim, streamlined valve design


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