9.7.4. Deploy the Contralateral Stub Leg of Bifurcated Component
While continuing to hold the Endurant Aortic Delivery System stationary with one hand on the front grip,
slowly rotate the slider counter-clockwise until the graft cover has withdrawn to the point that the
contralateral stub leg has been released from the delivery sheath as depicted in Figure 10.

9.7.5. Release Proximal End of Suprarenal Stent Crowns and Anchor Pins
Use angiography to verify the position of the bifurcated stent graft component in relation to the renal
arteries.
Continue to hold the Endurant Aortic Delivery System stationary with one hand on the front grip. With the
other hand, rotate the back-end wheel clockwise, moving the taper tip and metallic sleeve forward to
release the proximal end of the suprarenal stent as depicted in Figure 11. Observe the release of the
crowns and anchor pins at the proximal end of the suprarenal stent under fluoroscopy and continue turning
the back-end wheel until all parts of the suprarenal stent are completely clear from the spindle of the
delivery system. Confirm that the spindle has fully separated from the crowns of the suprarenal stent.
Note: In the unlikely event that the proximal end of the suprarenal stent cannot be released, refer
to Section 9.8 for bail-out techniques.
Note: It is recommended that the angiographic catheter be pulled down prior to release of the suprarenal
stent to prevent the anchor pins from binding the catheter shaft against the aorta.
Caution: When treating highly tortuous anatomy, in the unlikely event that the back-end wheel separates
during the rotation of the wheel, reassemble the wheel. A bail-out technique may be required. Refer
to Section 9.8 for bail-out techniques.
Caution: Make sure to stop rotating the back-end wheel when you reach the top of the back-end screw
gear.

9.7.6. Deploy Distal End of Bifurcated Component
There are two methods to deploy the distal end of the Bifurcated Component: either continue to rotate the
slider counter-clockwise or while holding the front grip of the delivery system stationary, use your thumb
to pull the trigger on the slider and pull the slider back all the way to finish deploying graft. Withdraw the
graft cover until the distal stent of the ipsilateral iliac component is completely deployed as depicted
in Figure 12.
