Abstract: This invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more links. A Y-shaped member is comprised of a U-shaped member and a link having a curved portion and a straight portion to improve the flexibility and thereby improve the fatigue performance of the Y-link junction.

Abstract: A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by one or more of a mechanical interference fit, a polymer coating or melt, and/or by friction. The marker can take the form of a bead, rivet or snap-in marker, or a tube deformed when attached to the strut. The strut is made from a tube. The strut has a thickness of about 100 microns.
