SYSTEM FOR BRANCHES FOR ENDOVASCULAR ENDOPROSTHESES AND CORRESPONDING ENDOPROSTHESIS FOR ENDOVASCULAR TREATMENT OF AORTIC ANEURYSMS OR DISSECTIONS

摘要

An internal duct and fixing system for branches for endovascular endoprostheses, and a corresponding endoprosthesis, for endovascular treatment of aneurysms or dissections of the aorta, including (i) an endoprosthesis provided with windows, (ii) one or more occlusions, fixed to the endoprosthesis by a suture, reversibly occluding the windows, and a set of fixing and duct elements that forms one or more internal channels of the endoprosthesis, preferably in the region adjacent to one of the windows.
