Christoph Miethke GmbH & Co. KG products

ONE valve for the unique requirements of a life with hydrocephalus: mobility, growth, changes in the course of disease. unique uncompromising pressure adaption to optimize individual patient needs. smallest adjustable gravitational valve worldwide. 2-in-1 technology: adjustable gravitational unit combined with fixed differential pressure unit in one valve. protected against over-drainage through individually and continuously adjustable opening pressure from 0-40 cmH2O. MRI-compatible up to 3 Tesla: no X-ray control after MRI necessary, no additional radiation exposure for the patient. protected against unintentional adjustment by means of exposure to magnets found in daily life, such as those used in smartphones, toys, induction cookers or safety barriers at the airport. Innovative M.blue plus Instruments for M.blue and proGAV 2.0. Intuitive, safe and comfortable adjustment. precise precision engineering. robust and durable: made of titanium.

More protection against over-drainage complications due to position-dependent function and infinitely variable pressure setting from 0-20 cmH2O. MRI compatible up to 3 Tesla: no X-ray control after MRI necessary, no additional radiation exposure for the patient. "Active-Lock" mechanism: protected against unintentional adjustment by means of exposure to magnets found in daily life, such as those used in smartphones, toys, induction cookers or safety barriers at the airport. "Soft Touch" instruments with enhanced magnetic force: intuitive, safe and comfortable adjustment. Precise precision mechanics. Robust and durable due to the use of titanium. Improvement of the X-ray recognition in the Scout View.

The GAV 2.0 is the consistent further development of the proven GAV and paediGAV and like its predecessors, it operates position-dependent and consists of a differential pressure and gravity unit. The GAV 2.0 must always be implanted parallel to the body axis for optimal function. It then automatically adapts its opening pressure to the different body positions of the patient and can thus meet the different requirements of a shunt system in lying and standing positions and, above all, counteract the risk of possible overdrainage in the upright body position.

The SHUNTASSISTANT 2.0 proves its strengths above all in partnership with other valves. Here, for example, it can be combined with a differential pressure valve to provide efficient overdrainage protection.

The paediGAV is the first pediatric valve for the treatment of pediatric hydrocephalus that works in a position-dependent manner and thus offers more protection against overdrainage complications.

The miniNAV was developed with the aim of offering the smallest possible valve with solid drainage control and at the same time avoiding the well-known problems such as blockage and dependence on subcutaneous pressure.

The DUALSWITCH-VALVE is the first MIETHKE valve. It was first implanted in 1995 at the Charité hospital in Berlin and quickly achieved very good results in clinical studies.

Hydrocephalus and subarachnoid hemorrhages may be associated with a life-threatening increase in intracranial pressure (ICP). Determining the ICP is an important requirement for proper application of ICP-lowering measures.¹⁰ To date, there is no way to adequately determine intracranial pressures based on symptoms or imaging methods alone. In addition to measurement for initial diagnosis, it may be necessary to monitor intracranial pressure repeatedly over a period of years to ensure the desired therapeutic outcome. The information gathered can help prevent time-consuming and costly examinations and hospitalizations, thus improving patient well-being. The M.scio is a long-term implant for simple, non-invasive telemetric measurement of intracranial pressure.
