    • A modular intraluminal stent graft. The intraluminal stent graft is bifurcated having a primary section and a secondary section extending therefrom. The primary section tapers from a larger diameter at an upstream end to a smaller diameter at a downstream end. The downstream end of the primary section has a pair of independent openings each having an expanded diameter. The secondary section provides a first endoleg having an upstream end that is received through the expanded diameter of one opening of the primary section, and a second endoleg having an upstream end that is received through the second opening of the primary section. The upstream ends of each endoleg, in its expanded state, is larger than the downstream portion of the respective endolegs and expands within the primary section to help assemble the graft in situ. The first and second endolegs also expand within the respective openings each is received within to assemble the stent graft in situ as well. The primary section is positioned within a blood vessel trunk, whereas the endolegs of the secondary section are positioned within a blood vessel branched from the blood vessel trunk. A typical application would be to place the primary section within the abdominal aorta infrarenally, with the endolegs positioned in the ipsilateral and contralaterial iliacs, respectively. By minimizing the number of stent segments in the primary section of the stent graft a lower delivery profile is achieved.
    • 模块化腔内支架移植物。 管腔内支架移植物分叉具有从其延伸的初级部分和次级部分。 初级部分从上游端的较大直径到下游端的较小直径变细。 初级部分的下游端具有一对独立的开口,各自具有扩大的直径。 次级部分提供第一内燃,其具有通过主部分的一个开口的扩展直径接收的上游端,以及具有通过主部分的第二开口接收的上游端的第二内燃。 在其膨胀状态下,每个内燃料的上游端大于相应内固体的下游部分,并且在初级部分内膨胀以帮助原位组装移植物。 第一和第二内固定体还在相应的开口内扩张,每个开口都被接收在内,以便在现场组装支架移植物。 主要部分位于血管干内,而第二部分的内固定体位于从血管干线分支的血管内。 典型的应用是将主要部分置于腹主动脉内,腹内主动脉分别位于同侧和对侧髂骨中。 通过最小化在支架移植物的主要部分中的支架段的数量,实现较低的输送曲线。

    • 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.
    • 本发明涉及一种特别适用于闭塞动脉瘤,血管侧分支或体腔或管道如动脉或静脉的解剖的管腔内薄膜医疗装置。 该医疗装置具有能够通过施加机械能纵向拉伸以获得更小的圆周轮廓并且在释放机械能时自扩张至预拉伸长度和直径的薄膜管。 为了在膨胀期间辅助薄膜,多个槽被切割在管壁中。 狭缝打开并帮助薄膜管纵向拉伸,并且当薄膜管自膨胀至预拉伸长度和直径时基本上闭合。

    • 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.
    • 提供了植入人体受试者内用于闭塞动脉瘤或体内血管的薄膜装置。 这些装置可以从细长的,折叠的构型移动,以便输送到主体内的展开构型。 当设备移动到其展开的构型时,在设备望远镜的选定部分中开放狭槽,这导致相关部分纵向缩短并且径向膨胀,同时孔隙度也降低以防止血液流动。 当装置移动到其展开构型时,装置的其它部分中的封闭狭缝打开,这导致相关部分纵向缩短并径向膨胀,同时保持开放以用于流体流动或内皮化。 闭塞装置可以是自支撑的或由支柱结构支撑。 另外,闭塞装置可以包括具有未对准孔系统的多个网眼层,其进一步降低展开构型的期望部分中的孔隙率。
