direction until a stable pressure of 230-240 mmHg is obtained
(Fig. 9). Ensure that the catheter remains in position during
the duration of the treatment. Misplacement of the catheter
during the treatment may lead to cervical canal burn.
CautioN
In case of unaddressed loss of pressure, abort the procedure
and do not reinsert the catheter. Determine the cause of loss
of pressure before considering further treatment ; please see
Warnings section.
14 Press the GREEN start key on the central unit once.
The circulation and the heating of the liquid in the balloon
will start (Fig. 10). The temperature will stabilise within the
operating mean temperature range of 70-80°C.
CautioN
Constantly maintain a balloon pressure of 230-240 mmHg
by gently turning the plunger clockwise (to increase the
pressure) or counter clockwise (to decrease the pressure).
A maximum volume of 30 ml must not be exceeded.
15 The heating and circulation continue until the treatment
time has elapsed.
END of proCEDurE
1 At the end of the treatment, the circulation and heating of
the liquid in the balloon stop automatically and a buzzer

4 Press the YELLOW stop keys on the central unit ; wait until
the pump compartment has opened completely ; a humming
sound should be heard; when the humming sound has
stopped, remove the catheter from the central unit.
CautioN
If the pump compartment does not open and the catheter
is not released, then make sure that the system pressure is
below 30 mmHg.
5 Press BLUE power on/off key on the central unit to switch
off the system.
6 The catheter connector contains a memory chip which
records treatment data. Should you desire to have the
memory chip analysed by Veldana Medical SA, then return
