Abstract: The present invention relates to an endoprosthesis for endovascular treatment of thoracic-abdominal aortic aneurysms or dissections, wherein the endoprosthesis has a proximal region, an intermediate region and a distal region, comprising five inner cylinders parallel to the longitudinal axis of the endoprosthesis, said inner cylinders, having elliptical apertures in the intermediate region. The present invention also relates to an endoprosthesis for endovascular treatment of abdominal aortic aneurysms or dissections which compromise the iliac arteries, wherein the endoprosthesis has a proximal region, an intermediate region and a distal region, comprising an inner cylinder parallel to the longitudinal axis of the endoprosthesis, said inner cylinder having an elliptical aperture in the intermediate region.

Abstract: A minimally invasive, percutaneous endovascular positioning device used for positioning or delivering other endovascular devices, such as staples, stents or bits, inside a blood vessel or hollow organ, comprises a cylindrical, catheter-like delivery device (1) that contains a guide tube (11), one, two, three or “n” delivery tubes (12) distributed uniformly around the guide tube (11), a head (14) at the top end of said guide tube (11) and articulated rods (13) that join the guide tube (11) to the delivery tubes (12), where the top end of the rod (13) is fitted into the head (14) and the lower end (131) of the rod (13) is hingedly connected to the delivery tube (12) or to supporting rods.

Abstract: “ENDOVASCULAR SUTURE STAPLE”, a component utilized for fastening a medical device to the wall of a blood vessel or inside a hollow body organ, may be specifically utilized for fastening vascular grafts on vessel walls, by means of endovascular sutures, comprised of a straight segment with its end trimmed to a pointed shape, and the posterior end(12) has a plain, straight, transversal section.
