INSTRUCTIONS FOR USE |

CONTRAINDICATIONS

The adjustable DP-unit should not be implan-
ted within an area which makes locating and
sensing the valve more difficult (e. g. under a
scar). The valve should lie on the periost or the
bone to make an adjustment after implantation
possible.
INTERACTIONS WITH PRODUCTS FROM
OTHER MANUFACTURERS
The proGAV with gravitational unit should not
be used under any circumstances in conjunc-
tion with hydrostatic valves, as this can bring
about abnormally high ventricular pressure
outside of the normal physiological range. Hy-
drostatic valves allow for changes in hydrosta-
tic pressure in the drainage system caused by
changes in position. If in doubt, please contact
the medical pro duct consultants at Christoph
Miethke GmbH & CO. KG.

RE-IMPLANTATION

Under no circumstances should products that
have had previously been implanted in a pati-
ent be subsequently reimplanted in another,
because a successfull decontamination of the
device cannot be reached without functional
degradation.

SAFETY MEASURES

The patients must be carefully monitored after
the implantation. Reddened skin and tension in
the area of the drainage tissue could indicate
infections at the shunt system. Symptoms such
as headache, dizzy spells, mental confusion or
vomiting are common occurrences in cases of
shunt dysfunction. Such symptoms, as well as
shunt system leakage, necessitate the imme-
diate replacement of the shunt component re-
sponsible, or of the entire shunt system
