Valve Flushing (Clearing Obstructions); Codman Certas Tool Kit Replacement; Warranty; Appendix A - DePuy Synthes Codman Neuro CERTAS Plus Manual Del Usario

CAUTION: A needle guard has been included in the
valve housing to provide tactile feedback during
needle insertion but is not intended to prevent
puncturing through the back of the valve under
forceful pressure.

Valve Flushing (Clearing Obstructions)

(Valves without SIPHONGUARD Device only)
CAUTION: While flushing may be used as a method
for determining patency, it is not recommended.
Use clinical judgment and imaging studies or
other techniques to confirm suspected cases of
shunt malfunction.
To flush the ventricular (proximal) catheter:
• Occlude the catheter distal to the reservoir with finger
pressure, then depress the reservoir.
• Failure of the reservoir to refill might indicate proximal
catheter blockage.
To flush the distal catheter:
• Occlude the catheter proximal to the reservoir with
finger pressure, then depress the reservoir.
• Failure of the reservoir to depress easily might indicate
distal catheter blockage.
Note: While proximal pressure is maintained, reservoir
will not refill with fluid.

Appendix A

Optional Manometer Testing

Although Codman does not recommend functional
testing, some surgeons might choose to do so. Before
testing, it is extremely important that a CODMAN CERTAS
Programmable Valve with or without SIPHONGUARD
Device be flushed of all air bubbles. Air bubbles within the
valve or SIPHONGUARD Device will produce inaccurate
manometer test results. The presence of air bubbles can
reduce the cross-sectional area of the flow path, increase
system resistance, and impede the flow of fluid through
the system during testing.

SIPHONGUARD Device Functional Testing

Equipment Required (use all sterile equipment, perform
testing under sterile conditions)
One sterile manometer, wide-bore (e.g. 3.5 mm),
graduated in mm (available in lengths from 38 to 60 cm)
