Pediatric VP shunt systems paedi-GAV
1) Paedi-GAV Operating Principles
Paedi-GAV shunt systems: Paedi-GAV specially developed for the treatment of pediatric hydrocephalus. As seen figure 1 in the two-valve consists of a combination.( ball-in-cone valve and gravitational valve ) This structure, Paedi-GAV of the patient’s hospital stay or automatically detect the position of the foot and again automatically appropriate opening ( pressure ) values allows you to run.
Paedi-GAV designed and produced a very small size and slightly larger than a catheter. Thanks to slippery surface is placed under the skin easily and much shorter duration of implantation. Although the valve sizes too small CSF in a relatively large flow channels and thus the risk of clogging the lowest level.
Picture 1: Paedi-GAV valve
In recent years, major advances in material technology with the recorded PaediGAV is made of titanium.
The advantages of titanium are:
- High bio-compatibility
- MRI compatibility
- High precision and reliability of production
- Durability
- The valve serial number on the opportunity to write the hard way
- With the material strength and durability and the functionality of the valve mechanism of internal and external (sc) not effected by pressure.
How does PaediGAV work?
In parallel to the axis of the valve implanted in the patient’s body works in a sensitive and reliable. When child lying PaediGAV is in a horizontal position. Ball-in-cone valve with IVP are controlled reliable. Gravitational valves in the open position because of the nature and not apply a force against so just ball-in-cone valve is working setpoint. Figure 2 in a horizontal position and the valve is closed.
Figure 2: PaediGAV horizontal position / off
Figure 3 in a horizontal position and the valve is open. With the increase IVP, conical valve spring force applied to bow the opening of the valve by pushing the cause and begin to drain.
Figure 3: PaediGAV horizontal position / on
The pressure in horizontal position ( during hospitalization )
Vertical case, located tantalum ball in the gravitational valve force creates an extra weight. So PaediGAV in vertical position of the valve as a combination of two separate works. When childres stood up gravitational valve automatically closes ( tantalum ball go down the hole closed down due to weight ) and cut off drainage. (Figure 4.) If the IVP and because of standing hydrostatic pressure of increases in total and compressive force both the ball-in-cone valf at the bow and the defeat tantalum ball weight in that part of the gravitational valve, drainage begins again so that the two valve become clearly (figure 5). When after drainage the pressure desired level, valves will be closed again.

Paedi-GAV models:
1. Paedi-GAV Flushing with Resorvoir (4062 Series)
Resorvior ventricular is on the catheter.
Flushing with resorvoir (with pes planus resorvoir) this model shunt has two parts and it needs to be one ligature. Body of valve and distal catheter are together.Resorvoir and right angle are on the ventricular catheter Ventriküler.Morover;stylet helps for the positioning.They have many kinds of this about the different pressure.

3. Paedi-GAV Borehole with Resorvoir (4071 Series)
Flushing with resorvoir (with pes planus resorvoir) this model shunt has three parts and it needs to be two ligature. Morover;stylet helps for the positioning on the ventricular catheter.There is the 20 cm catheter of ligature on the Borehole resorvoir’s borehole at the cusp of disatl. Body of valve and distal catheter are together. They have many kinds of this about the different pressure.
