4.
Ensure RHS marker red line containing red dot is aligned
with the RHS marker of the x-ray image (if present).
5.
The valve setting is determined by identifying the
region of the overlay that contains the majority of
the image of the magnet that has the tantalum ball
adjacent to it.
Injection
If hypodermic injection is required, inject with a 25-gauge
or smaller non-coring HUBER
®
type needle into the
reservoir
only
. The reservoir can be punctured up to
25 times with a 25-gauge or smaller non-coring HUBER
type needle.
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.
