The proGAV 2.0 is a valve system made of
titanium. It consists of an adjustable differen-
tial pressure unit (1) and a gravitational unit (5)
(Abb. 1).
The adjustable differential pressure unit (1) in
the proximal part of the valve system consists
of a stable titanium housing with an integrated
ball-cone valve (3) in the front section. A torsion
spring (2) determines the opening pressure of
this unit. The pretension of the spring, and thus
the valve opening pressure, can be adjusted
post-surgically through the skin using a pivoted
rotor (4).
Major components of the gravitational unit (5)
are a tantalum ball (6), which defines the open-
ing pressure for this valve depending on body

position, and a sapphire ball (7), which ensures
precise closure.
The proGAV 2.0 XABO consists of an proGAV
2.0 valve system in combination with XABO
Catheters.
XABO Catheters are made from silicone, they
are impregnated with antibiotics in a spe-
cial treatment process and contain 0.054%
rifampicin and 0.15% clindamycin hydrochlo-
ride. Laboratory test have shown XABO
Catheters to reduce colonisation with gram-
positive bacteria of the silicone catheter sur-
face. The laboratory tests were performed with
Staphylococcus aureus, Staphylococcus epi-
dermidis and Bacillus subtilis. Systemic thera-
peutic e ects are highly unlikely as the amounts
of rifampicin and clindamycin hydrochloride
