Codman offers a complete line of CSF Shunting products to aid in the management of Hydrocephalus. We use the proven ball and cone design to offer precise control in both our fixed pressure and programmable valves. The SIPHONGUARD Anti-Siphon device uses a unique dual pathway to reduce the effects of siphoning, while BACTISEAL Antimicrobial impregnated catheters prevent the colonization of gram positive bacteria on the catheter surface. Our shunts come in a variety of configurations to meet your specific needs.

The CODMAN HAKIM Programmable
Valve offers the ability to optimize the opening pressure
of a shunt system before and after implantation. A shunted
patient's condition will often change over the course
of their treatment. The programmable valve allows a surgeon
to non-invasively change the opening pressure between
30mm H2O and 200 mm H2O in 18 steps; negating the need
for revision surgery to alter the valve pressure. The
programmability of the valve may allow for the development
of specialized treatment regimes. The opening pressure
of the CODMAN HAKIM Programmable Valve is changed
through the use of an externally applied, codified magnetic
field. The spring in the ball and spring mechanism of
the valve sits atop a rotating spiral cam which contains
a stepper motor. Applying a specific magnetic field to
the stepper motor will cause the cam to turn slightly,
increasing or decreasing the tension on the spring and
ball, thus changing the opening pressure of the valve.
The CODMAN HAKIM Programmable Valve is available in eight
basic configurations, and each of these configurations
can be purchased with a unitized distal catheter or valve
only.

The CODMAN HAKIM Precision Fixed Pressure valve offers
5 distinct and narrow bandwidths to assure the correct
pressure setting for each individual case. It also uses
the proven ball and cone technology to insure that each
pressure range is correct within a + / -10mm H2O variance.
The CODMAN HAKIM Precision Fixed Pressure Valve is available in eight
basic configurations, and each of these configurations
can be purchased with a unitized distal catheter or as
a valve only.
A technically innovative anti-microbial
impregnated catheter system designed to reduce gram positive
bacteria on catheter tube surfaces. BACTISEAL silicone
catheters have been shown in laboratory studies to reduce
the colonization of gram positive bacteria on the tubing
surface.

SIPHONGUARD Anti-Siphon device
is a unique new device for preventing excessive CSF flow
during positional changes. The SIPHONGUARD device
is integrated into the current Programmable and Precision
Fixed Pressure Valve technologies, as well as a stand-alone device. The
SIPHONGUARD device can be placed anywhere distal
to the valve and is unaffected by scar tissue encapsulation
or external pressure. The mechanical design detects the
difference between the normal and excessive flow and closes
the primary pathway only when excessive flow occurs. The
secondary pathway is always open and allows for the slow
release of CSF when the primary pathway is closed.
The SIPHONGUARD Anti-Siphon device never totally
closes the shunt system but instead uses resistance to
impede flow. The SIPHONGUARD device utilizes proven
ball and cone technology, which is highly reliable.
