| 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. |
