7. DIRECTIONS FOR USE, CORONARY MEASUREMENTS
7.1.
Engage the guiding catheter using standard practice. Flush the catheter.
CAUTION:
A guiding catheter with 6F (2 mm) size or larger should be used to prevent
damping of the arterial pressure signal. Larger size should be considered when
large interventional catheters are used.
7.2.
Carefully insert the distal tip of the guidewire into the hemostatic valve of
the Y connector and then advance the wire into the catheter.
7.3.
Position the sensor element of PressureWire
guiding catheter.
7.4.
Pull back the insertion tool out of the hemostatic valve.
7.5.
Tighten the hemostatic valve.
7.6.
Place the aortic pressure transducer at the same height as the patient´s
heart. Make sure there is no remaining contrast fluid in the catheter, flush if
necessary.
7.7.
Verify that the aortic pressure from the guiding catheter and the

To remove any residual pressure difference between aortic and

monitor system or use the plus (+) and minus (–) buttons on
PressureWire
monitor or the Instructions for use for PressureWire
WARNING:
When introducing the guidewire, confirm that the catheter tip is free within the
vessel lumen and not against the vessel wall. Failure to do so may result in vessel
trauma upon guidewire exit of the catheter. Use the radiopaque marker of the
catheter to confirm position.
7.9.
Advance PressureWire
to steer PressureWire
measurement.
WARNING:
Observe all PressureWire
