Adjustable valves

for more flexibility

Adjustable and individual

- as life itself

Hydrocephalus is a disease that occurs at any age and can be very restrictive for patients. Depending on the cause of the hydrocephalus, there is the desire for a valve to give back as much freedom and quality of life as possible. Against the background that not only is every person different, but no two hydrocephalus are alike - not even in the life of a single patient - it is becoming increasingly important for individual treatment that valves can be flexibly adjusted.

The adjustable valves from MIETHKE can be adjusted from 0 to 20 cmH2O (differential pressure valves) and 0 to 40 cmH2O (gravitational valves) postoperatively and non-invasively.® & plus®

The balanced way of life.

The is the essence of 26 years of experience with hydrocephalus and valve technology and the feedback of numerous doctors and patients worldwide. In developing this valve, we have paid particular attention to the needs of an active life with hydrocephalus. On average, we are active 16 hours a day and in very different ways. The is a gravitational valve that allows us to react flexibly to different requirements. Different from patient to patient and different within a life with hydrocephalus.

The is a combination of an adjustable gravitational unit and an integrated, fixed differential pressure unit - 2 in 1.

The plus is a combination of adjustable gravitational unit and adjustable differential pressure unit.

about the product


The MIETHKE App shows clearly and quickly understandable how our valves work:

+ Influence of the body position on the opening pressure: The motion sensor of the smartphone simulates the body position of the patient: upright - inclined - lying.

+ Pressure stage recognition in the X-ray image: Every set or preset pressure stage is shown here and can be easily recognized by means of templates.

+ Simulation of adjustability: Valves can be easily adjusted with the finger and thus help to understand what is happening inside the valve.

+ View into the inside of MIETHKE valves: All valves allow a view of their construction and thus the influence of the cerebrospinal fluid flow on the functioning can be shown in an easily understandable way.

The MIETHKE Journal is a platform for a broad spectrum of technologies and questions that doctors and patients inevitably encounter at some point in the treatment of hydrocephalus with shunt systems.
Hydrocephalus is our topic. Every day. Full-time.
