Figure 9: Hold the green stability sheath. DO NOT hold or touch the brown moving sheath.
Note: DO NOT constrict the delivery system during stent deployment. If excessive force is felt during stent deployment, do
not force the stent system. Remove the stent system and replace with a new unit.
• Initiate stent deployment by rotating the large thumbwheel (labeled 2 on the system grip) in the direction of the arrows,
while holding the handle in a fixed position (Figure 10).

• While using fluoroscopy, maintain position of the distal and proximal stent radiopaque markers relative to the targeted
site.
• Watch for the distal stent radiopaque markers to begin separating; separation of the distal stent radiopaque markers
signals that the stent is deploying. Continue turning the large thumbwheel until the distal end of the stent obtains
complete wall apposition (Figure 11).

3. Introduce Stent System
• Advance the stent system over the guidewire through the introducer sheath. For contralateral access, always use a long
introducer sheath that covers the aortic bifurcation.
Note:
If resistance is met during stent system introduction, the stent system should be withdrawn and another stent
system should be used.
Caution: Always use an introducer sheath for the implant procedure to protect the vasculature and the puncture site.
• Position the tip of the stent system past the target site.
4. Deploy Stent
• Confirm that the introducer sheath is secure and will not move during deployment.
• Pull back the stent system until the distal stent radiopaque marker is placed distally to the target site to ensure full
coverage of the lesion.
• The second hand should be used to support the stent delivery system. Gently hold the stability sheath close to the
introducer sheath and keep it stationary and under tension throughout deployment (Figure 7).
• Remove slack from the stent system held outside the patient.
Caution:
Any slack in the stent system (outside the patient) could result in deploying the stent beyond the target site.
• Unlock the safety lock slider by pulling it back towards the wheels from the locked position into the unlocked position.
Ensure that the red safety lock slider is completely pulled back (Figure 8).
