proGAV ® 2.0 XABO ®
The proGAV 2.0 Adjustment Instrument is cen-
tred over the valve. The recess in the middle of
the tool makes it easy to identify the valve by
touch using the index finger to place the tool
correctly Fig. 13). When doing so, the required
pressure level must be displayed on the scale
in the direction of the valve inlet or the Ventric-
ular Catheter.

proGAV 2.0 Adjustment Instrument
Lightly pressing the index finger on the
adjustable unit releases the rotor brake and
changes the pressure level of the proGAV 2.0
(Fig. 14).

The differential pressure unit of the proGAV 2.0
is fitted with a feedback mechanism. Due to
the valve housing design, targeted pressure on
the valve produces an audible acoustic sig-
nal (a clicking sound) and/or palpable resis-
tance as soon as the rotor brake has been
released. The valve thus shows both acousti-
cally and haptically when the pressure is suf-
ficient for uncoupling. Once this pressure has
been released, the rotor is once again adjust-
ment-proof. Although the click caused by
releasing the rotor brake is easily audible before
implantation, it may be considerably reduced

after implantation and the filling of the valve
depending on its position and the condition of
the implant surroundings. Normally, however, it
should be audible to the patient or by using a
stethoscope.
After adjusting the valve opening pressure, it is
recommended to check the set pressure level.
To do this, proceed as in Points 1 and 2. Should
the measured value not correspond with the
required pressure level, the adjustment process
should be repeated. To do this, start again at
Point 3.
proGAV Checkmate
The proGAV Checkmate (Fig. 15) is supplied
sterile and can be re-sterilised. The proGAV
Checkmate can be used to change and check
the pressure level before and during valve
implantation directly on the proGAV 2.0. To
determine the pressure level, the proGAV
Checkmate is placed centrally on the proGAV
2.0. The proGAV Checkmate automatically
aligns itself over the valve. The pressure level
can be read from the direction of the proximal
catheter (leading towards the valve). For pres-
sure level adjustment, the proGAV Checkmate
is placed centrally on the proGAV 2.0. When
doing so, the required pressure level must point
towards the proximal catheter (leading towards
the valve). Lightly pressing the proGAV Check-
mate onto the valve releases the rotor brake in
the proGAV 2.0 and sets the pressure level.

To protect the impregnation, the proGAV 2.0
XABO is wrapped in opaque packaging. How-
ever, it is still possible to check and adjust the
setting of the proGAV 2.0 XABO.
