ADVERSE REACTIONS
In the treatment of hydrocephalus with shunts,
the following complications may arise (as
described in the literature): infections, block-
ages caused by protein and/or blood in the
cerebrospinal fluid, over-/underdrainage or in
very rare cases noise development.
Violent shocks from the outside (accident, fall
etc.) may put the integrity of the shunt system
at risk.
STERILISATION
The products are sterilised with steam under
closely monitored conditions. The expiry date
is printed on the wrapping of each individ-
ual product. Products taken from a damaged
wrapping must not be used under any circum-
stances.
RESTERILISATION
The functional safety and reliability of rester-
ilized products cannot be guaranteed, there-
fore resterilisation is not recommended.
PRESSURE-FLOW CHARACTERISTICS
The diagrams below show the pressure-flow
characteristics for the pressure ratings in
which the miniNAV is available.
INSTRUCTIONS FOR USE | GB
Fig. 6: The total opening pressure refers to a ref-
erence flow of 5 ml/h. When the flowrates reach
20 ml/h, the opening pressures are approximately
1 to 2 cmH 2 O higher.
