7
Insert the delivery system into the vasculature until the distal
radiopaque marker of the extension is aligned at the distal target. Use
continuous fluoroscopic guidance to ensure proper positioning of the
stent graft.
8
Verify the appropriate position of the extension relative to the iliac limb
and vasculature.
9
Retract sheath to deploy stent graft while maintaining catheter handle
position.
10
Maintain position of sheath and use catheter handle to retract
nosecone to sheath.
11
Remove delivery system from vasculature while maintaining guidewire
position.
12
Advance and inflate an appropriate size non-compliant balloon in the
overlap region. Follow the manufacturer’s recommended method for
size selection, preparation, and use of balloons.
13
Re-insert angiographic catheter and advance to the suprarenal aorta.
Perform deployment completion angiography as described above.
11. Follow-up Imaging Recommendations
TriVascular recommends the following imaging schedule for patients treated with the
Ovation Abdominal Stent Graft System.

Patients should be counseled on the importance of adhering to the recommended
follow up schedule during the first year and annually thereafter. More frequent follow-
up may be required for some patients based on clinical evaluation.
TriVascular recommends contrast enhanced Spiral CT data for reconstruction. The
requirements are outlined in Table 7.
