摘要： A stent includes a series of helical windings defining an outer circumference of a cylinder. The helical windings include a plurality of struts having straight portions connected by curved portions. The straight portions may be substantially aligned with a longitudinal axis of the stent when the stent is in a reduced state. A plurality of bridges connect adjacent windings. The bridges may be substantially orthogonal to the longitudinal axis of the stent in the reduced state. A plurality of radiopaque members extend from a terminal helical winding. The radiopaque members include an extension portion and an end portion. The extension portion may have a first width and the end portion may have a second width greater than the first width. The end portion may include an extreme end substantially orthogonal to the longitudinal axis of the stent.

摘要： An implantable prosthesis designed to transition from a contracted state to an expanded state, including a continuous tubular helical winding and a plurality of bridges. The helical winding includes a plurality of circumferential sections spaced apart along a helical axis, each of the plurality of circumferential sections forming a non-orthogonal helical angle relative to the helical axis. The plurality of bridges connect adjacent circumferential sections, each having a length extending from a first end to a second end on a plane orthogonal to the helical axis, the length being equal to a circumferential offset between the adjacent circumferential sections in both the contracted state and the expanded state. The implantable prosthesis also includes a first annular ring orthogonal to the helical axis, and a first marker having a first end connected to the first annular ring, and a second end coupled to the first end of the helical winding.

摘要： Preferred embodiments of a stent with a high degree of flexibility are shown and described. The stent can include a continuous helical winding and at least one bridge. The continuous helical winding has a plurality of circumferential sections that circumscribe a longitudinal axis from a first end to a second end to define a tube. The circumferential sections are spaced apart along the axis. The at least one bridge is configured to connect one circumferential section to an axially-spaced adjacent circumferential section. The at least one bridge extends on a plane generally orthogonal with respect to the axis.
