Abstract
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.
Claims15
An internal duct and fixing system for branches for endovascular endoprostheses for endovascular treatment of aortic aneurysms or dissections, said system comprising:
- (i) a endoprosthesis provided with fenestrations;
- (ii) one or more occlusions, fixed to the endoprosthesis by means of suture, reversibly occluding the fenestrations, and
- (iii) a set of fixing and duct elements that forms one or more internal channels of the endoprosthesis.
An endoprosthesis for endovascular treatment of aortic aneurysms or dissections, wherein said endoprosthesis comprises:
- (i) a structure and a coating forming a cylindrical or conical, single or bifurcated tubular body, wherein the outer mantle of the coating is provided with fenestrations;
- (ii) one or more occlusions, fixed to the coating by means of suture, reversibly occluding the fenestrations, and
- (iii) a set of fixing and duct elements, which can be:
- (iii-a) a set of flexible fixing and conducting arches, individually fixed to the coating;
- and/or
- (iii-b) a set of rigid fixing and conducting rings, individually fixed to the coating;
- wherein the set of fixing and duct elements forms one or more internal channels of the endoprosthesis.
