The procedure steps can be summarized as follows:
(1) The delivery catheter is inserted and advanced from the femoral artery at the top of the leg into position in the aorta. The stent graft is positioned using fluoroscopy.

(2) When the stent graft is in the correct position, the main body is deployed. Channels in the main body are then filled with polymer to create a seal against the aorta and provide support for the graft.

(3) The limbs are then inserted into the main body and deployed in position. This completes the stent graft and creates a new path for the blood to flow.
