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 undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and sufficient radial strength to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since the inside radii of curvature of some of the peaks and valleys allow the stent to be crimped to a very low profile onto a catheter and increase radial strength over prior art stents.
