Step
Procedure
2
Prepare and insert the Edwards Expandable Introducer Sheath Set. Refer to the Edwards Expandable
Introducer Sheath Set IFU for information on device preparation and handling.
3
Insert the loader into the sheath until the loader stops.
4
Advance the N delivery system, with the Edwards logo facing up, through the sheath until the
valve exits the sheath. Retract the loader to the proximal end of the delivery system.
NOTE: Maintain the proper orientation of the flex catheter (with the Edwards logo facing up)
throughout the procedure.
CAUTION: If accessing femorally or via the iliac, the valve should not be advanced through the
sheath if the sheath tip is not past the aortic bifurcation.
CAUTION: To prevent possible leaflet damage, the valve should not remain in the sheath for over
2 minutes.
5
In a straight section of the aorta, initiate valve alignment by pressing the button, begin pull back of the
balloon catheter, and release the button.
Continue pulling back the balloon catheter until the delivery system locks into the valve alignment
position (Refer to
Figure
2c
).
Use the Valve Alignment Wheel to position the valve between the valve alignment markers.
CAUTION: Do not turn the Valve Alignment Wheel if the delivery system is not locked in the Valve
Alignment Position.
WARNING: Do not position the valve past the distal Valve Alignment Marker. This will prevent
proper valve deployment.
CAUTION: Maintain guidewire position in the left ventricle during valve alignment.
6
Advance the catheter and use the flex wheel, if needed, and cross the aortic valve.
NOTE: Verify the Edwards logo is facing up. The delivery system articulates in a direction
opposite from the flush port.
7
If additional working length is needed, remove the loader by unscrewing the loader cap and peeling the
loader tubing from the delivery system.
8
Press the button and retract the Flex Catheter to the Double Marker and position the valve within the
aortic annulus.
9
Verify the correct position of the valve with respect to the valve.
10
Begin valve deployment:
•
Unlock the Inflation device provided by Edwards Lifesciences.
•
Begin rapid pacing; once systolic blood pressure has decreased to 50 mmHg or below, balloon
inflation can commence.
•
Deploy the valve by inflating the balloon with the entire volume in the Inflation device provided by
Edwards Lifesciences, hold for 3 seconds and confirm that the barrel of the inflation device is empty
to ensure complete inflation of the balloon. Deflate the balloon. When the balloon catheter has been
completely deflated, turn off the pacemaker.
7.3.4 System Removal
Step
Procedure
1
Unflex the delivery system while retracting the device, if needed. Retract the flex catheter until it locks in
the default position and remove it from the sheath.
CAUTION: Patient injury could occur if the delivery system is not unflexed prior to removal.
2
Remove all devices when the ACT level is appropriate. Refer to the Edwards Expandable Introducer
Sheath Set instructions for use for device removal.
3
Close the access site.
