Abstract: 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.

Abstract: A stent graft (40) for treating Type-A dissections in the ascending aorta (22) is provided with a plurality of diameter reducing suture loops (56-60) operable to constrain the stent graft during deployment thereof in a patient's aorta. The diameter reducing loops (56-60) allow the stent graft (40) to be partially deployed, in such a manner that its location can be precisely adjusted in the patient's lumen. In this manner, the stent graft can be placed just by the coronary arteries (26, 28) with confidence that these will not be blocked. The stent graft (40) is also provided with proximal and distal bare stents (44,52) for anchoring purposes.

Abstract: A balloon expandable covered stent consists of a plurality of primary stent units, each having an undulating shape defined by a series of primary strut members converging to form peaks and valleys. The primary stent units are assembled into a single cylindrical structure of the stent by connecting corresponding peaks with secondary strut members. Generally, surfaces of the stent may then coated with a polymeric, hyper-elastic material, preferably Thoralon®, by pre-expanding the stent prior to coating.

Abstract: A perfusion device and a delivery system for repair of a damaged portion of a body vessel. Perfusion device can include a tubular body that is self-expandable, having a proximal portion, a distal portion, and an intermediate portion. One or more series of barbs can be disposed circumferentially along the intermediate portion. Barbs are capable of penetrating into the tunica intima and tunica media of said vessel wall upon insertion of said device into said body vessel, and not into said tunica adventitia. A graft can be associated with the tubular body. Graft has a proximal end and a distal end, and preferably extends entirely along a luminal wall of the tubular body. Graft may also extend along an exterior surface of the tubular body at the proximal and distal portions. A remodelable covering can be applied along the intermediate portion. Delivery devices for the perfusion implant and methods of delivering the perfusion implant are also provided.
