stays below the cut-out. If there is too much tissue
protrusion, use the Adjustable Height Locator
Tool instead.
CAUTION: 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
above the valve. In these instances, verify the
valve setting with x-ray or fluoroscopy. Refer to
SECTION D: Troubleshooting and SECTION E:
Confirming the Current Valve Setting.
so that the red markings are aligned (Figure 11). You
may hear a click when the tool seats. The indicator
tool will not rotate within the locator tool when
properly seated.
CAUTION: When reading the performance setting
with the Indicator Tool, make sure that the
Adjustment Tool and any other magnetic devices
are at least 36 cm (14 in.) away from the Indicator
Tool. Failure to do so can result in an inaccurate
indication of the performance setting.
moving, observe the number and its position within
the window to determine the performance setting.
A single number within the window that has the full
purple background and both gray side lines visible
(Figure 13) indicates the performance setting of the
valve when the tools are properly aligned. Once the
valve performance setting has been read, remove the
Indicator Tool.
Note: If a single number with the purple background
and both gray side lines are not fully visible, then
the Locator Tool is not accurately aligned with the
valve. Remove the Indicator Tool and reposition
the Locator Tool, ensuring the black center lines
are centered with the valve mechanism (Figure 10).
Repeat Steps 1 through 6.
CAUTION: Do not move the Locator and Indicator
Tools together to obtain or center a number in
the window as this could result in an inaccurate
indication of the performance setting.
that the arrow is pointing to the current performance
setting. With one hand holding the "petals" of the
Locator Tool, turn the Adjustment Tool with the
other hand until the arrow points to the desired
performance setting (Figure 12). The Adjustment Tool
will provide an audible click and a tactile response as
you turn to each setting.
CAUTION: Failure to accurately position the
Locator Tool could result in an inability to adjust
the performance setting. 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 adjustment. Alignment can be more
