SHUNTASSISTANT® & paediSHUNTASSISTANT®

The gravitational assistants for children and adults

FEATURES

  • two product variants: for children and adults
  • more protection against overdrainage complications due to position-dependent function
  • MRT compatible up to 3 Tesla
  • compatible for a complementary partnership with other valves
  • slim, cylindrical and small design for a better flow
  • precise precision engineering
  • robust and durable due to the use of titanium

FUNCTIONALITY

The SHUNTASSISTANT and the paediSHUNTASSISTANT are used to control overdrainage. Their strengths are particularly evident in combination with other valves.

Both valves are separate gravitational valves which automatically adjust their opening pressure to the body position and thus counteract possible overdrainage in the upright body position. Like all position-dependent valves, they should always be implanted parallel to the body axis. Both can be ideally combined with other, conventional valves (e.g. differential pressure valves). It does not matter whether the MIETHKE SHUNTASSISTANT is placed before or after the differential pressure valve. Also the installation height has no influence on the mode of operation.

Horizontal Position

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

 

 

 

 

 

 

 

 

 

Vertical Position

When the patient stands up, the SHUNTASSISTANT is activated: The balls inside the housing close the passage of the valve due to the gravitational forces, thus automatically increasing the opening pressure and protecting 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 pushed upwards and release the passage until the cerebral pressure has decreased accordingly. In the vertical position of the body, the total opening pressure is the sum of the opening pressure of the gravitational valve and the opening pressure of another differential pressure valve in use.

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 (10, 15, 20, 25, 30 and 35 cmH2O):

 

pressure stage 10 cmH2O (paediSA)

 

 

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.

+ free for Apple and Android
