Abstract:

The present invention relates to an internal duct and fixing system (100) for branches for endovascular endoprostheses for endovascular treatment of aneurysms or dissections of the aorta, comprising (i) an endoprosthesis (200) provided with windows (210, 220, 230, 240), (ii) one or more occlusions (215, 225, 235, 245), fixed to the endoprosthesis (200) by means of suture (216, 226, 236, 246), reversibly occluding the windows (210, 220, 230, 240), and a set of fixing and duct elements (300) that forms one or more internal channels of the endoprosthesis (200), preferably in the region adjacent to one of the windows (210, 220, 230, 240). The present invention also relates to a corresponding endoprosthesis (200).
