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.

Claims

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.

2. The method of claim 1, wherein a stent-graft delivery device is used to deliver the stent-graft from the first location to the second location.

3. The method of claim 2, wherein the stent-graft is disposed within a sleeve of the stent-graft delivery device in the radially compressed configuration and the sleeve is retracted to deploy the stent graft from the radially compressed configuration to the radially expanded configuration.

4. The method of claim 2, wherein the step of rotating or translating the stent-graft comprises the steps of:

recapturing the stent-graft such that the stent-graft is radially compressed from the radially expanded configuration to a second radially compressed configuration;

rotating or translating the stent-graft while in the second radially compressed configuration; and

expanding the stent-graft from the second radially compressed configuration to a second radially expanded configuration such that the fenestration is not aligned with the second opening.

5. The method of claim 4, wherein a recapture catheter is used to recapture the stent graft.

6. The method of claim 5, wherein the recapture catheter and the stent-graft delivery device are the same device.

7. The method of claim 6, wherein the step of deploying the stent-graft at the second location such that the stent-graft expands from the radially compressed configuration to the radially expanded configuration comprises the stent-graft delivery device maintaining control of a distal stent of the stent-graft.

8. The method of claim 1, wherein the first opening is through a wall of the left brachial artery.

9. The method of claim 8, wherein the second opening is through a wall of the left subclavian artery or the left axillary artery.

10. The method of claim 9, wherein the third location is adjacent the aortic valve.

11. The method of claim 10, wherein after the step of advancing the delivery device to the third location, a prosthetic aortic valve is deployed from the delivery device.

12. The method of claim 1, wherein the first opening is through a wall of the right brachial artery.

13. The method of claim 12, wherein the second opening is through a wall of the right subclavian artery or the right axillary artery.

14. The method of claim 13, wherein the third location is adjacent the aortic valve.

15. The method of claim 14, wherein after the step of advancing the delivery device to the third location, a prosthetic aortic valve is deployed from the delivery device.

16. The method of claim 1, wherein a radiopaque ring is coupled to the graft material around a periphery of the fenestration.

17. The method of claim 16, wherein a portion of the graft material around the fenestration is folded over the radiopaque ring and the graft material is stitched to itself to capture the radiopaque ring.
