Our smallest hydrocephalus shunt

The MIETHKE miniNAV® was developed as a compact differential pressure valve which, due to its small design, is particularly suitable for the treatment of pediatric hydrocephalus, especially in premature and newborn infants.[1] Another area of application is hydrocephalus in bedridden patients.

The valve is made of titanium, a material that allows excellent precision, stability and biocompatibility.


  • Very small, slim, cylindrical design for easy implantation ​
  • MRI compatible upto 3 Tesla​
  • Smallest differential pressure valve [1]


The MIETHKE miniNAV® is available as a single product or as a shunt system with different components.
