MIETHKE M.blue®

Adjustable gravitational valve for the treatment of hydrocephalus

M.blue® is the essence of over 28 years of experience with valve technology for the treatment of hydrocephalus and is based on feedback from numerous doctors and patients worldwide. 
M.blue® focuses on the patient's active time, which is mostly spent sitting or upright and takes up about 2/3 of a day. This is where the greatest risk of positional overdrainage exists. 
With its adjustable gravitational unit and a wide adjustment range of 0-40 cmH2O, the valve can be adapted to the individual requirements in life with hydrocephalus: mobility, growth and changes in the course of the disease ^{[1], [2], [3], [4]} 
The M.blue® is a position-dependent hydrocephalus valve. It consists of an adjustable gravitational unit and a fixed differential pressure unit. 
Particularly challenging and difficult forms of hydrocephalus require a much higher degree of flexibility in treatment. This is what the M.blue® plus stands for: a combination of adjustable gravitational unit and adjustable differential pressure unit (proGAV® 2.0).
