Special valve design for patients with increased level of tumor cells, debris or blood cells Description A high protein level or tumor cells in the CSF can lead to valve blockage. These issues were given particular consideration in the development of the MIETHKE DualSwitch® Valve. The special design of the valve presents a very large surface area to the CSF, thus ensuring reliable operation even in contaminated fluid. Clinical studies also demonstrate successful treatment of patients with so-called normal pressure hydrocephalus (NPH). The MIETHKE DualSwitch® Valve is made from titanium, a material that guarantees outstanding precision, reliability and biocompatibility. Advantages - Automatic switch of opening pressure - Large surface area to CSF - Reliable even with contaminated fluid Indication - Treatment of Hydrocephalus Note The MIETHKE DualSwitch® Valve is available as a single valve or as a shunt system with different components.
