  • Shunt infection: How it develops and how it can be prevented
    • Shunt therapy is the most common treatment for hydrocephalus, but carries the risk of serious complications such as shunt infections. Find out more about symptoms, causes, treatment options and preventive approaches such as antibiotic-impregnated catheters.
  • LP shunt vs. VP shunt
    • The choice between LP and VP shunt is essential for the successful treatment of hydrocephalus. This article provides a detailed comparison, looking at the indications, benefits and potential risks of both types of implantation - informed insights for better treatment decisions.
  • The measurement of intracranial pressure (ICP)
    • The measurement and interpretation of intracranial pressure (ICP) is a very helpful aid in the diagnosis and treatment of many brain diseases. The article explains the technical requirements for ICP measurements, the interpretation of ICP values in intracranial pressure measurements and their significance for effective treatment planning.
  • The Innovative Leap to Telemetric Pressure Sensors
    • Telemetric pressure sensors are setting new standards in the hydrocephalus shunt therapy. The article analyzes the technical limitations of conventional ICP sensors and presents trend-setting innovations in the field of measurement with telemetric pressure sensors - for more precise and efficient treatments.
  • Over- and underdrainage - the most common “side effects” of shunt systems
    • Shunt systems in hydrocephalus therapy have a long history, but over- and underdrainage are still common complications with their potential consequences, such as slit ventricle syndrome. The article looks at the causes, consequences and therapeutic approaches of both problems and discusses whether gravitational technology offers a possible remedy.
  • Foundations of fluid mechanics, or of beakers, bottles and people
    • The article introduces fluid mechanics and explains how the cerebrospinal fluid works in the human brain. It explains the hydrodynamics in the shunt system and shows why the circulation and pressure of the cerebrospinal fluid are important factors for optimizing shunt therapies.

FUNCTIONALITY

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 SHUNTASSISTAN 2.0 is the consistent further development of the proven SHUNTASSISTANT and paediSHUNTASSISTANT. Like its predecessor, it is a separate gravitational valve that automatically adjusts the valve opening pressure to the different body positions of the patient and can thus counteract possible overdrainage while standing.

The SHUNTASSISTANT 2.0 can be integrated into the shunt system at any position. The installation height has no influence on the functionality. However, the correct position parallel to the body axis is important for the proper functioning of this gravitational valve.

The slim, cylindrical design of the SHUNTASSISTANT 2.0 has been further optimized for a better flow and the valve has been reduced in size once again. Combined with the different pressure levels offered, this valve is equally suitable for the treatment of hydrocephalus in adults and children.

Horizontal Position

The SHUNTASSISTANT 2.0 is open in the lying body position and does not present any resistance. The opening pressure in the horizontal body position is determined exclusively by another differential pressure valve which is used.

Vertical Position

When the patient rises, the SHUNTASSISTANT 2.0 is activated: The balls inside the housing close the passage of the valve due to the gravitational force, automatically increasing the opening pressure and thereby protects the patient from overdrainage while standing. Only when the patient's cerebral pressure increases to such an extent that the opening pressure in the valve is reached, the balls are pressed upwards and open the passage until the cerebral pressure has fallen again. In the upright body position, the total opening pressure is the sum of the opening pressure of the gravitational valve and that of the additional differential pressure valve.

PRESSURE LEVEL DETECTION IN X-RAY IMAGE

Each preset pressure stage is specially coded and can be recognized postoperatively in imaging. The lower illustrations show the X-ray images of all available pressure stages of the SA 2.0 (10, 15, 20, 25, 30 and 35 cmH2O):

pressure stage 10 cmH2O

 

pressure stage 15 cmH2O

 

pressure stage 20 cmH2O

 

pressure stage 25 cmH2O

 

pressure stage 30 cmH2O

 

pressure stage 35 cmH2O

 

For detailed information on the optimum pressure stage setting, please refer to our pressure stage recommendation. 

 

 

MIETHKE APP - UNDERSTANDING VALVES EASILY


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.
