摘要： 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.

摘要： An intravascular stent is provided to be implanted in coronary arteries and other body lumens. The transverse cross-section of at least some of the stent struts have a ratio of polar and bending moments of inertia, which results in optimal resistance to stent twisting. This resistance to twisting ratio for the stent struts minimizes out of plane twisting of the struts or projecting edges of the struts when the stent is expanded from a compressed diameter to an expanded diameter in a coronary artery.

摘要： A stent or scaffold has a tapered end or ends. The scaffold is made using an additive manufacturing technique such as stereolithography (SLA). The scaffold may take the shape of a frustum, or a scaffold having one or both of its ends flared. The scaffold has varying mechanical properties over its length, such as a varying ring stiffness, porosity or elasticity modulus. In one embodiment the strut and link widths change linearly from the distal to proximal ends.
