POSSIBLE SHUNT COMPONENTS

The paediGAV is available with different shunt
accessories. These variants consist of a varie-
ty of components, which are described briefly
below:
The Burrhole reservoir is positioned in the
cranial burrhole. It allows measuring the in-
traventricular pressure, injecting drugs and
extracting CSF. Its solid titanium base is high-
ly puncture-resistant. All reservoirs are availa-
ble with integrated catheters or connectors.
A special Burrhole reservoir is the SPRUNG
RESERVOIR. As additional new feature of this
reservoir CSF can be flushed towards the val-
ve because of a one-way valve in the bottom
of the reservoir. By this mechanism a flow
in the direction of the ventricular catheter is
avoided during the pumping procedure. The
opening pressure of the shunt system is not

increased by the implantation of the SPRUNG
RESERVOIR.
The prechamber is positioned on the craniu m.
It allows measuring the intraventricular pressu-
re, injecting drugs, extracting CSF and perfor-
ming a palpatory ventricle inspection. Its solid
titanium base is highly puncture-resistant.
A puncture of the prechamber or the CONTROL
RESERVOIR should be performed as perpendi-
cular to the reservoir surface as possible with
a cannula of max. 0,9 mm. 30 times of punc-
tures are able without any restrictions. A special
prechamber is the CONTROL RESERVOIR. As
an additional new feature of this reservoir, CSF
can be flushed towards the valve because of a
one-way valve in the proximal inlet of the reser-
voir. By this mechanism a flow in the direction
of the ventricular catheter is avoided during the
pumping procedure. The opening pressure of
the shunt system is not increased by the im-
plantation of the CONTROL RESERVOIR.
Warning note: Frequent pumping can lead
to overdrainage and thus to unphysiological
pressure conditions. The patient should be
informed about the risk.
Due to its tight fit on the ventricular catheter, the
deflector allows choosing the length of catheter
penetrating into the skull prior to implantation.
The ventricular catheter is deflected at a right
angle in the burrhole

TUBE SYSTEMS

The paediGAV has been designed to ensure the
optimal ventricular pressure. It is available as a
shunt system or as individual valve units with
or without an integrated distal catheter (internal
diameter 1.2 mm, external diameter 2.5 mm).
Individual valve units should be used with ca-
theters of approx. 1.2 mm internal diameter and
approx. 2.5 mm external diameter.
The connector on the valve allows using ca-
theters of 1.0 mm to 1.5 mm internal diameter.
The external diameter of the catheter should
be about double the internal diameter. In any
case, the catheters must be carefully fixed, with
a ligature, to the valve connectors. Kinks in the
catheter have to be avoided.
The provided catheters have virtually no effect
on the Pressure-flow characteristics.
