摘要： An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D−24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters.

摘要： Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system may comprise proximal and distal components, each comprising a graft having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component may comprise a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices may be greater than the radius of curvature of at least one of the distal apices. The distal component may comprise a proximal z-stent coupled to the graft, where the proximal end of the graft comprises at least scallop formed therein that generally follows the shape of the proximal z-stent. Further, the distal component may comprise at least one z-stent stent coupled to the distal end of the graft and extending distally therefrom that reduces proximal migration of the distal component.

摘要： An attachment system for attaching an intravascular device to a vessel wall of a body vessel is disclosed. The attachment system has an intravascular device having a first end and a second end. The intravascular device defines a longitudinal axis along a length thereof. Several struts are connected to one or more ends of the intravascular device. Each strut is configured to move along a strut path relative to the longitudinal axis between an expanded state for engaging the vessel wall and a collapsed state for delivery or retrieval. Each strut has a free end configured to engage the vessel wall in the expanded state.

摘要： A beam is provided for intraluminal devices. The beam is defined by a first side surface and a second side surface. The first side surface is tapered at a different rate than the second side surface. One advantage of the beam is that strain which is normally concentrated in adjacent, interconnected bends is redirected onto the length of the beam. This may increase the fatigue life of intraluminal devices or may be used to fashion new structures with improved performance.
