Abstract

A stent graft system for intraluminal deployment in an aorta and a branch vessel includes an aorta stent graft with a fenestration aligned with a branch vessel and a branch vessel prosthesis with a flaring portion at a proximal end and a tubular portion. When deployed, the flaring portion of the branch vessel prosthesis is retained within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel. The system includes at least one positional indicator, including a positional indicator associated with the branch vessel prosthesis for indicating the position of a point along the branch vessel prosthesis predetermined for optimal alignment with the fenestration during deployment.

Claims

1. A stent graft system for intraluminal deployment in an aorta and a branch vessel comprising:

an aorta stent graft with a fenestration aligned with a branch vessel;

a branch vessel prosthesis with a flaring portion at a proximal end and a tubular portion, wherein, when deployed, the flaring portion is retained within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel; and

a first positional indicator associated with the branch vessel prosthesis for indicating the position of a point along the branch vessel stent graft predetermined for optimal alignment with the fenestration during deployment.

2. The system of claim 1 further comprising a second positional indicator on the aorta stent graft indicating the position of the fenestration.

3. The system of claim 2 further comprising a third positional indicator associated with the branch vessel prosthesis for indicating the position of a distal end of the branch vessel prosthesis during deployment.

4. The system of claim 3 further comprising a fourth positional indicator associated with the branch vessel prosthesis for indicating the position of a proximal end of the branch vessel prosthesis.

5. The system of claim 2 further comprising a fourth positional indicator associated with the branch vessel prosthesis for indicating the position of a proximal end of the branch vessel prosthesis.

6. The system of claim 1 wherein the first positional indicator is located on the branch vessel prosthesis.

7. The system of claim 1 wherein the first positional indicator comprises a radiopaque material.

8. The system of claim 1 wherein the first positional indicator is located on a device for deploying the branch vessel prosthesis.

9. The system of claim 7 wherein the first positional indicator comprises a radiopaque material.

10. The system of one of claims 1, 2, 3, 4 or 5 wherein at least one of the positional indicators is shaped so as to indicate position and orientation of the branch vessel prosthesis.

11. The system of one of claims 1, 2, 3, 4 or 5 wherein at least one of the positional indicators is v-shaped with one leg longer than the other.

12. A stent graft system for intraluminal deployment in an aorta and a branch vessel comprising:

an aorta stent graft with a fenestration aligned with a branch vessel;

a branch vessel prosthesis with a flaring portion at a proximal end and a tubular portion, wherein, when deployed, the flaring portion is retained within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel; and

a first positional indicator associated with the branch vessel prosthesis for indicating the position of a point along the branch vessel prosthesis predetermined for optimal alignment with the fenestration during deployment.
