GB | INSTRUCTIONS FOR USE
CAUTION
The M.blue plus Adjustment Ring emits a mag-
netic field. Metallic objects and magnetic
storage media should be placed at a suffi-
cient safety distance.
4. Checking after adjustment
After adjusting the valve opening pressure, it
is recommended to check the selected open-
ing pressure. To do this, please proceed as in
Points 1 and 2. If the measured pressure does
not agree with the required pressure stage
the adjustment process should be repeated.
To do this, please start at Point 3 again.
Adjustment can be made difficult by swelling
of the skin for a few days after the opera-
tion! If checking the valve setting is not 100%
possible using the M.blue plus Compass, we
recommend carrying out a check using an
imaging method.
M.blue Check-mate
The M.blue Check-mate is supplied sterile and
can be re-sterilised. With the M.blue Check-
mate it is possible to carry out a pressure level
change and the check before and during valve
implantation directly on M.blue. To determine
the pressure level the M.blue Check-mate is
placed centrally on M.blue. The M.blue Check-
mate automatically aligns itself over the valve.
The pressure stage can be read off from the
catheter in the proximal (leading to valve)
direction. If the pressure level is supposed to
be adjusted, the M.blue Check-mate is placed
centrally on M.blue. When doing so, the
required pressure stage must point towards
the proximal catheter (leading to valve). If the
M.blue adjustment gyroscope is now pressed
lightly onto the valve, the rotor brake in M.blue
is released and the pressure level is set.
When adjusting, please ensure that the open-
ing pressure is changed by a maximum of
16 cmH O per adjustment process otherwise
2
errors can result (see Chapter "3. Adjustment
process").

CAUTION
Because of the magnets inside the M.blue
plus Instruments, M.blue plus Instruments may
not be used in the vicinity of active implants
such as heart pacemakers. Furthermore,
there is risk of damage to MRI instruments in
their vicinity. Therefore, usage of M.blue plus
Instruments is forbidden in such locations!
It is absolutely essential to use only the M.blue
plus Instruments to determine, adjust and
monitor the opening pressure of M.blue.

M.blue with proGAV 2.0 (M.blue plus)
The instruments can also be used for localis-
ing, reading and setting the adjustable differ-
ential pressure unit of proGAV 2.0. When com-
bining the M.blue valve with the adjustable
differential pressure unit of the proGAV 2.0,
the M.blue valve is localised, checked and
adjusted as described under points 1-4. The
adjustable differential pressure unit (proGAV
2.0) can also be localised, checked and
adjusted to a desired value between 0 and
O with the M.blue plus Instruments,

as described under points 1-4. For the open-
