Abstract
In a method of accessing and closing a vessel, a vessel is percutaneously accessed through a first opening in the vessel wall at a first location. A stent-graft is delivered through the first opening to a second location. The stent-graft is deployed at the second location. The vessel is then accessed through a second opening through the vessel wall at the second location, wherein the second opening is generally aligned with a fenestration through the graft material of the stent-graft. A delivery device is advanced through the second opening, the fenestration, and the stent-graft lumen to a third location spaced from the first location and the second location. After the delivery device is retracted through the lumen of the stent-graft and out of the fenestration and the second opening, the stent graft is rotated or translated such that the fenestration is not aligned with the second opening.
