and the entry into, the peritoneum by means of
a trocar, the peritoneal catheter (shortened, if ne-
cessary) is pushed forward into the open space
in the abdominal cavity.

PreoPeratIve valve test

Isotonic sterile sodium chloride solution
Fig. 19: Patency test
The proGAV 2.0 can be filled by aspiration through a sterile, single-
use syringe attached to the distal end of the catheter. The proxi-
mal end of the valve is immersed in a sterile, physiological saline
solution. The valve is patent if fluid can be extracted in this way
(see fig. 19).
Caution: Pressure admission through the single-use syringe
should be avoided, both at the proximal and the distal end.
Contaminations in the solution used for the test can impair the
product's performance.

Vertical position
The opening pressure of the proGAV 2.0 in the vertical position
is the sum of the opening pressure of the adjustable dP-unit and
the gravitational unit.
