Abstract: An expandable stent for implantation in a body lumen, such as an artery, is disclosed. The stent consists of a plurality of radially expandable cylindrical rings generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting links placed so that the stent is flexible in the longitudinal direction. The link pattern is optimized to enhance longitudinal flexibility and high longitudinal strength compression of the stent.

Abstract: A thin-walled scaffold includes a radiopaque marker connected to a link. In a first example, the marker is retained on the strut by a head at one or both ends by swaging. In a second example of a thin-walled scaffold the link is modified to avoid interference during crimping. In a third example a distal end of the thin-walled scaffold is modified to improve deliverability of the thin-walled scaffold. These features are combined in a fourth example.

Abstract: Methods are disclosed including thermally processing a scaffold to increase the radial strength of the scaffold when the scaffold is deployed from a crimped state to a deployed state such as a nominal deployment diameter. The thermal processing may further maintain or increase the expansion capability of the scaffold when expanded beyond the nominal diameter.
