Possible Shunt Components - MIETHKE proGAV 2.0 Mode D'emploi

GB | INSTRUCTIONS FOR USE
If the pressure configuration of the valve can-
not be determined with complete certainly by
the proGAV 2.0 Compass, the use of imaging
techniques is recommended.
proGAV Check-mate
The proGAV Check-mate is delivered sterile
and is intended to be re-sterilised. It is possi-
ble to change and to verify an applied pres-
sure setting on the valve directly. To verify
the actual pressure setting the proGAV Check-
mate has to be put centrally over the valve.
The proGAV Check-mate will immediately start
to move. If it remains stable, the pressure set-
ting can be read in alignment to the inlet con-
nector. To adjust a new pressure setting, the
proGAV Check-mate has to be placed cen-
trally over the valve. The new pressure set-
ting has to point towards the proximal catheter
(leading to the ventricle). By pressing down
slightly the proGAV Check-mate, the brake of
the valve is decoupled, the rotor turns and
the opening pressure of the proGAV 2.0 is
changed.
Please be aware that the steps for changing
the pressure setting should not be more than
8 cmH O per step.

CAUTION
Due to magnets inside the proGAV 2.0 Tools,
do not use the proGAV 2.0 Tools nearby pace-
makers. Further more do not use the proGAV
2.0 Tools nearby MRI scanner, since ther is a
danger of damaging the MRI-scanner.
M.blue plus Instruments
In addition to the described proGAV 2.0 Tools,
the M.blue plus Instruments can also be
used for locating, reading and adjusting the
adjustable differential pressure unit of the pro-
GAV 2.0.

When combining proGAV 2.0 with M.blue
(adjustable gravitational unit), the M.blue plus
Instruments can also be used to locate, read
and adjust the pressure level of the M.blue
(adjustable gravitational unit).

POSSIBLE SHUNT COMPONENTS

The proGAV 2.0 can be ordered as a shunt
system in a range of configurations. The
configurations can be combined with the
accessories presented in brief below. In
each case, versions for paediatric hydro-
cephalus and for normal pressure hydro-
cephalus (NPH) in adults are available.
Reservoirs
The use of a reservoir in combination with
shunt systems provides options for the with-
drawal of cerebrospinal fluid, administration of
drugs and pressure control.
Due to the non-return valve of the SPRUNG
RESERVOIR and the CONTROL RESERVOIR,
cerebrospinal fluid can be pumped towards
the valve, thus making it possible to check
the distal part of the drainage system as
well as (proximal) ventricular catheter. Dur-
ing the pump action, access to the ventricular
catheter is closed. The use of reservoirs does
not increase the opening pressure of the shunt
system. A puncture should be performed as
perpendicular as possible to the reservoir sur-
face with a maximum cannula diameter of 0.9
mm. 30 punctures are possible without any
restrictions.
WARNING
Frequent pumping can result in excessive
drainage and thus lead to pressure condi-
tions outside the normal physiological range.
The patient should be properly informed
about this risk.
