    摘要： Universal endovascular grafts are provided for evaluation and repair of damaged or aneurismal blood vessels. More particularly, the present invention relates to universal fenestrated and universal branched endografts for repair of blood vessels with branches, methods for implanting the endografts in the vessel and for making connection with one or more branches. The universal fenestrated endografts have a body with a first end, a second end, a first wall, a second wall, and an interior passage or lumen. The body further includes openings in communication with the passage at the first and second ends and one or more lateral fenestrations in communication with the lumen. The body further has a necked portion between the ends and a cannulation member. The universal branched endografts have a tubular body with a main lumen and four branch lumens. A large branch extends from the body. The four lumens are positioned about a circumference of the tubular body.

    摘要： A system and method of remote guidance and alignment for endovascular fenestration of a vascular prothesis placed intraluminally that includes a flexible magnetic guide sheath having a magnetic distal end. An implantable magnetic stent for intraluminal placement in proximal end of a target artery providing magnetic guidance outside the endovascular aortic stent graft prothesis for accurate aperture formation in the vascular prothesis for subsequent placement of covered branch stents thereto.

    摘要： A covered stent (100A), including a mesh-shaped support structure, and further including a first section (10A) and a second section (20A) connected to a proximal end and/or a distal end of the first section. The first section includes a plurality of first corrugated rings (11A), and a first covering film (12A) which covers surfaces of the first corrugated rings; the second section includes a plurality of second corrugated rings (21A), two adjacent second corrugated rings being fixedly connected to each other; a plurality of windows (201A) are formed between the plurality of second corrugated rings; and the plurality of first corrugated rings and the plurality of second corrugated rings form the support structure. The second section of the covered stent will not block an opening of a branch vessel (400), and thus it is not necessary to reduce the length of the covered stent in a main branch vessel, such that the covered stent has a sufficiently long anchoring area in the main branch vessel so as to ensure that the covered stent has sufficient anchoring force and thus prevent the displacement or endoleak of a distal end of the covered stent, thereby ensuring a good occluding effect.
