MIETHKE DUALSWITCH VALVE
Gravitational valve with extra large flow path

The MIETHKE DUALSWITCH is a valve for the different types of adult hydrocephalus. 
A high protein content or tumour cells in the CSF can lead to a blockage of a valve. These aspects were given special consideration in the development of the MIETHKE DUALSWITCH VALVE. The special design of the valve provides the CSF with a very large surface area, so that reliable function is guaranteed as far as possible even in contaminated fluid. [1,3]

To also reduce overdrainage complications, the valve is also equipped with gravitational technology. Clinical studies show good efficacy here. [1,2 3,4,5,6,7,8,9]

The MIETHKE DUALSWITCH VALVE is made of titanium, a material that allows excellent precision, reliability and biocompatibility.

Indication:

  • Treatment of Hydrocephalus
