Description

The NOVUS and NOVUS Mini Valves
are silicone elastomer valves used for
the treatment of hydrocephalic patients
when shunting cerebrospinal fluid
(CSF) from the ventricles of the brain.
The valves incorporate an internal low,
medium or high pressure valve
assembly which is mounted distal to an
integral pumping reservoir for proximal
control of CFSF flow. The devices also
provide one-way flow control. An
integral occluder is incorporated on the
proximal end of the valves, while an
integral Physiological Flow Device is
mounted on the distal end and also
serves as an occluder. The occluder
and Physiological Flow Device are
designed to manually control the
flushing or pumping of CSF proximally
or distally. The devices are fitted with a
polypropylene needle guard, designed
to prevent inadvertent needle puncture
during percutaneous injection. The
valves contain an integral plastic
connector on each end to simplify the
assembly procedure. The valves
contain no metal parts to interfere with
computerized axial tomography. Due to
the internal reservoir capacity, no
separate reservoir is usually required
(Figures 1 and 2).
