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.

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 translation: 公开的方法包括当支架从卷曲状态展开到展开状态（例如标称展开直径）时，热处理支架以增加支架的径向强度。 热处理可以进一步维持或增加支架在膨胀超过公称直径时的膨胀能力。
