Abstract

A stent for vascular interventions having a hybrid open cell geometry. Variants of the stent include bare metal stents and drug-eluting stents. Embodiments of the stent include end projections for radiopaque markers or a discontinuous partial radiopaque coating on low-stress or low-strain regions of the peripheral stent. The stents of the invention are characterized by having thin walls, nested rows of struts, high expansion ratio, high and uniform radial force over entire diametric size and length of device, crush resistance up to and including about 90% of its fully expanded diameter, high fatigue resistance and high corrosion resistance.
