SYSTEM OF FIXATION AND INTERNAL CONDUCTION OF RAMS FOR ENDOVASCULAR ENDOPROSTHESIS AND CORRESPONDING ENDOPROSTHESIS FOR ENDOVASCULAR TREATMENT OF AORTA DISEASES OR DISEASES

摘要

The present invention relates to a system for fixation and internal conduction of branches for endovascular stent grafts for endovascular treatment of aortic aneurysms or dissections, comprising (i) an endoprosthesis (200) having fenestras (210, 220, 230, 240), (ii) one or more occlusions (215, 225, 235, 245) fixed to the stent graft (200) by suturing (216, 226, 236, 246) reversibly occluding the fenestras (210, 220, 230 240), and a set of fastening and driving elements (300) forming one or more internal channels of the stent graft (200), preferably in the region adjacent to one of the fenestras (210, 220, 230, 240). The present invention further relates to a corresponding stent graft (200).
