    摘要: Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft comprises first and second stents, which each may comprise a series of distal apices disposed distal to a proximal end of the graft, and a series of proximal apices disposed proximally beyond the proximal end of the graft. In one example, the first stent comprises a first uniform segment, and the second stent comprises a second uniform wire segment, where the first uniform segment comprises portions disposed both internal and external to the second uniform wire segment.

    摘要: The present examples provide a stent for use in a medical procedure that comprises at least one apex having first and second generally straight portions and a curved portion disposed between the first and second straight portions. The curved portion may comprise at least one region having a cross-sectional area that is less than a cross-sectional area of the first and second straight portions, which may facilitate compression of the stent and insertion of the stent into smaller vessels. The stent may be used alone, or in conjunction with a stent-graft, and may comprise one or more barbs configured to engage an inner wall of a vessel or duct.

    摘要: The present invention provides a system and a method for forming in vivo a junction between a first and a second element of a modular endovascular prosthesis used for repairing defects in vessels and other lumens within the body of a patient. The first element is adapted to have a receiving element, and the second element is adapted to have a protruding element. In the final deployed configuration of the endovascular prosthesis, the protruding element of the second element is adapted to be engaged with the receiving element of the first element, substantially preventing axial separation of the elements relative to each other. The receiving element of the invention may have various forms, and may include a fold in the wall of the first element, an expandable framework having protruding struts, or a flexible thread. The protruding elements of the invention may be formed from an expandable framework having protruding struts, or may be formed from a fold in the wall of the second element, or may comprise a flexible thread.
