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: A balloon comprising: a center portion having a proximal end, a distal end opposite the proximal end, and a length between the proximal end and the distal end. The center portion comprises: a first nominal diameter and a first radial modulus at the proximal end; a second nominal diameter and a second radial modulus at the distal end; further wherein, the first nominal diameter is equal to the second nominal diameter, such that, when the balloon is inflated to a nominal pressure, the center portion has a constant diameter over the length; and further wherein, the first radial modulus is smaller than the second radial modulus, such that, when the balloon is inflated above a nominal pressure, the center portion adopts a tapered shape in which the proximal end has a first stretched diameter and the distal end has a second stretched diameter, the first stretched diameter being larger than the second stretched diameter.

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.
