Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by links. The links between adjacent rings provide axial strength when subjected to longitudinal compressive forces.

Abstract: A scaffold strut is shaped to improve hemocompatibility. The scaffold is made from a tube having variable wall thickness. Methods are disclosed for modifying the thickness of the tube in such a way as to achieve a reduced hemodynamic profile, but without significantly affecting strength properties in areas where stress concentrations exist when the scaffold is loaded.
