Do not use any of the CODMAN CERTAS Tool
Kit components on a metal surface, such as
a Mayo stand as this could interfere with the
Indicator Tool magnets.
Note: the Adjustment Tool contains
powerful magnets.
Inspect the CODMAN CERTAS Tool Kit
components before each use. Check for
damage, such as cracks. Do not use the Tool Kit
if damage is present. Contact your local Codman
sales representative for a replacement kit.
Carefully monitor the patient during the first
24 hours after adjusting the performance
setting of the valve. It is recommended that
each adjustment be limited to an increase or a
decrease of one setting, since setting changes
can range between 15 and 50 mmH
Confirm the valve performance setting after
an MR procedure.
Excessive swelling may make it difficult to
determine and/or adjust the performance setting.
See Step 4 in SECTION B: Post-
o
Implantation Adjustment Procedure for
instructions for using the Low Profile
Locator Tool in these instances.
If difficulty correctly positioning both Locator
o
Tools persists, wait until the swelling is
reduced or confirm the valve setting with
x-ray. See SECTION D: Confirming the
Current Valve Setting for more information.
Failure to accurately position the Locator
tool could result in an inaccurate indication of
the performance setting, potentially leading to
a false reading (i.e. an incorrect number may
appear in the window of the Indicator Tool).
The Locator Tool must be precisely aligned
with both the valve's direction of flow and the
center of the hard valve mechanism for an
accurate indication reading. Alignment can be
more challenging if tissue thickness is >10 mm
