    摘要： An abdominal aortic aneurysm endoprosthesis having a reduced profile for percutaneous delivery of the endoprosthesis. The endoprosthesis provides a cranial section supported by a stent, and a bifurcated caudal section having at least two legs each of which are supported by individual stents. The individual stents of each leg of the caudal section are staggered so as not to line up with one another. Altering the lengths of the legs permits nesting of the endoprosthesis. Optimizing the expansion ratio and radial strength of the endoprosthesis is achieved by altering the dimensions of the starting material from which the stent segments are fabricated, by altering the final austentite temperature of the starting materials, or by changing the structural configuration of the stent segments. A graft material is attached to at least a portion of the cranial section and to all of the caudal section of the endoprosthesis.

    摘要： The present invention relates to an intraluminal thin film medical device particularly well suited for occlusion of an aneurysm, vessel side branch or dissection of a body lumen or duct, such as an artery or vein. The medical device has a thin film tube capable of being longitudinally stretched by the application of mechanical energy to achieve a smaller circumferential profile, and self-expand to the pre-stretched length and diameter upon release of the mechanical energy. To assist the thin film during expansion a plurality of slots are incised in the tube wall. The slots open and assist the thin film tube to longitudinally stretch, and substantially close when the thin film tube self-expands to the pre-stretched length and diameter.

    摘要： A method of occluding a defect in the wall of a body vessel is provided. An outlet portion of a microcatheter is delivered to the defect, then at least a body portion of a thin film occlusion device is radially expanded from a collapsed orientation to a deployed orientation for engaging the microcatheter and covering at least a portion of the defect. Thereafter, an embolic media is released into the defect from the microcatheter for facilitating thrombosis. The body portion of the occlusion device is substantially porous in the collapsed orientation, but substantially non-porous in the deployed orientation for preventing prolapse of the embolic media into the body vessel.

    摘要： Thin film devices implantable within a human subject for occlusion of an aneurysm or body vessel are provided. The devices are movable from an elongated, collapsed configuration for delivery to a deployed configuration within the body. Open slots in selected portions of the device telescope as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while also decreasing in porosity for preventing blood flow. Closed slits in other portions of the device open as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while remaining open for fluid flow or endothelialization. The occlusion devices may be either self-supporting or supported by a strut structure. Additionally, the occlusion devices may comprise a plurality of mesh layers having unaligned pore systems which further reduce porosity in desired portions of the deployed configuration.
