Stent-graft and method for percutaneous access and closure of vessels
First Claim
1. A method for accessing a vessel comprising the steps of:
- percutaneously accessing a vessel through a first opening in a wall of the vessel at a first location;
delivering a stent-graft in a radially compressed configuration through the first opening to a second location spaced from the first location, wherein the stent-graft includes at least one stent, graft material coupled to the at least one stent, a first end, a second end, a lumen, and a fenestration through the graft material between the first end and the second end;
deploying the stent-graft at the second location such that the stent-graft expands from the radially compressed configuration to a radially expanded configuration;
accessing the vessel through a second opening in the vessel wall at the second location, wherein the second opening is generally aligned with the fenestration in the stent-graft such that the lumen of the stent-graft can be accessed through the second opening and the fenestration;
advancing a delivery device through the second opening, the fenestration, and the stent-graft lumen to a third location spaced from the first location and the second location;
retracting the delivery device through the lumen of the stent-graft and out of the fenestration and the second opening; and
rotating or translating the stent-graft such that the fenestration is not aligned with the second opening.

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.
