Devices and methods for treatment of the aortic arch
First Claim
1. An endoprosthetic assembly for treating a main vessel and at least one branch vessel extending from the main vessel, the endoprosthetic assembly comprising:
- a first expandable device and a second expandable device, each having a generally tubular shaped wall comprising a trunk portion configured for engaging the main vessel;
reduced diameter portions of each of the first and second devices having reduced diameters relative to their respective trunk portions, at least one of the reduced diameter portions being concentrically offset from a trunk portion to which it is coupled, and the first and second devices being configured to engage each other telescopically; and
at least one branch for treating the at least one branch vessel and extending through a fenestration in one of the reduced diameter portions.

Abstract
The present disclosure includes an endoprosthesis comprising a descending stent-graft, an ascending stent-graft, and/or a side-branch stent-graft. In various embodiments, an ascending stent-graft is capable of being coupled to a descending stent-graft, and/or a descending stent-graft can comprise a fenestration capable of being coupled to a side-branch stent-graft. In addition, in various embodiments, a descending and/or ascending stent-graft can comprise a reduced diameter portion that, when implanted within an aortic arch, recedes from a luminal surface of the aortic arch to allow a side-branch stent-graft to be maneuvered within the aortic arch.

12. A method comprising:
-
precannulating a side-branch artery with a guidewire prior to deploying a descending stent-graft, wherein the guidewire abuts a luminal surface of the side-branch artery to facilitate deployment of the descending stent-graft; deploying the descending stent-graft within the descending portion of an aortic arch; deploying an ascending stent-graft within an ascending portion of the aortic arch; and deploying a side-branch stent-graft through a fenestration in one of the ascending stent-graft and the descending stent-graft. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
