Abstract
First and second stent-grafts are provided. The first stent-graft defines a first lateral opening, and is configured for positioning a first end thereof in a descending aorta, and a second end thereof in one of the branches of an aortic arch, with the first lateral opening disposed in the aortic arch facing upstream. The second stent-graft includes a second generally tubular support element and a second covering element that partially covers the second support element. The first and the second stent-grafts are configured such that the second stent-graft forms a blood-impervious seal with the first stent-graft around the first lateral opening when the second stent-graft is disposed therethrough such that a proximal portion of the second support element is disposed within the first stent-graft. The second covering element does not fully cover the proximal portion, thereby allowing blood flow through the first stent-graft. Other embodiments are also described.
