First Claim
Patent Images
1. An endoluminal vascular repair system comprising:
- an aorta stent graft having a fenestration and a first reinforcement around the fenestration, wherein the fenestration is aligned with a branch vessel when deployed;
a branch vessel stent graft having a flaring portion at a proximal end of the branch vessel stent graft, and a tubular portion, wherein the flared portion retains the proximal end within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel when deployed, and wherein the flaring portion comprises a second reinforcement around its circumference adapted to engage the reinforcement around the fenestration.

Abstract
An endoluminal vascular repair system includes an aorta stent graft having a fenestration with a first reinforcement around the fenestration. The fenestration aligns with a branch vessel when deployed. A branch vessel stent graft has a flaring portion at a proximal end of the branch vessel prosthesis that has a second reinforcement around its circumference to engage the reinforcement around the fenestration, and a tubular portion. When deployed, the flaring portion retains the proximal end within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel.

20. A method of effecting an endoluminal vascular repair comprising:
-
deploying an aorta stent graft having a fenestration and a first reinforcement around the fenestration, so that the fenestration is aligned with a branch vessel;
deploying a branch vessel stent graft having a flaring portion with a second reinforcement around a proximal end of the branch vessel stent graft, and a tubular portion, so that the flared portion retains the proximal end within the aorta stent graft, and so that the tubular portion extends through the fenestration and into the branch vessel, and so that the second reinforcement engages the first reinforcement.
