    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 system for controlling multiple guidewires comprises a guiderail, which has a housing that defines a first guidewire lumen and a second guidewire lumen. The guidewire lumens extend through the entire length of the guiderail. The guiderail housing further defines a first longitudinal opening that extends from the first guidewire lumen to the exterior of the guiderail, and a second longitudinal opening that extends from the second guidewire lumen to the exterior of the guiderail.

    摘要: In one embodiment, an apparatus for shaping an article may comprise a plurality of movable dies arranged to form a chamber whose size may be varied by moving the dies. Each of the dies may have a contacting surface for contacting the article to be shaped. The chamber may have a first portion having a first cross-section and a second portion having a second cross-section. Either portion may include a taper. The first portion may have a differently shaped cross-section than the second portion. The first portion may have a cross-section of greater area than the second portion. The longitudinal axis of the first portion may be offset from the longitudinal axis of the second portion.
