Abstract:
1. Apparatus comprising a multi-component stent-graft system, which comprises: a first generally tubular stent-graft, which (i) when unconstrained in a radially-expanded state: (a) defines a first lateral opening having a first lateral opening perimeter, and (b) has a first perimeter of a first end thereof that equals at least 200% of a second perimeter of a second end thereof, and (ii) is configured for positioning the first end thereof in a descending aorta, and the second end thereof in one of the branches of an aortic arch, with the first lateral opening disposed in the aortic arch facing upstream; and a second generally tubular stent-graft, which is configured to assume a radially-expanded state, wherein 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, and the first and second stent-grafts are in their radially-expanded states.
