    摘要: Techniques are disclosed that allow a stent to be folded within a balloon of a stent delivery system. In one example, a stent has first and second columns that extend from a proximal end to a distal end along a longitudinal axis. Each of the first columns extend substantially parallel to the longitudinal axis and comprise a plurality of elements that each have a substantially polygonal shape. Each of the second columns extend substantially parallel to the longitudinal axis and are between adjacent first columns. Each of the respective second columns include a plurality of first connectors that have a curvilinear shape and that extend in a substantially circumferential direction to connect adjacent first columns. The stent also has a plurality of second connectors, wherein at least one of the second connectors extends between a first element and a second element.

    摘要: An endoprosthesis includes an expandable tubular body defined by a plurality of struts. In some embodiments, the expandable tubular body includes a bioerodible metal that has at least a first surface region and a second surface region. The first and second surface regions can have different surface oxide compositions. In some embodiments, the first portion has a thermally altered microstructure and the second portion has a wrought microstructure. The thermally altered microstructure can be a cast microstructure comprising dendritic grains. The first portion forms at least a portion of an outer surface of the expandable tubular body. In some embodiments, the expandable tubular body includes iron or a bioerodible iron alloy and at least one surface of the expandable tubular body includes a substantially uniform coating of iron(III) oxide.

    摘要: A catheter assembly comprises a catheter having a catheter shaft with a first rotatable sheath rotatably disposed thereabout. A first guidewire housing which defines a first guidewire lumen for passage of a first guidewire therethrough is engaged to the first rotatable sheath. A first stent, which when in the reduced stent state, is disposed about at least a portion of the first rotatable sheath. A second stent, which when in the reduced stent state, is positioned adjacent to the first stent.
