1. A stent for treating a vascular bifurcation, comprising:

  • a first proximal end, a second distal end and a longitudinal axis therebetween;

    a plurality of segments extending coaxially end to end along the longitudinal axis, each segment consisting of a single ring which forms a circumference of the stent, wherein each single ring comprises a plurality of struts extending in an end to end manner creating a zig zag pattern in which each strut extends from a proximal end of said each single ring to a distal end of said each single ring,wherein the stent is expandable from a reduced diameter to an expanded diameter and configured to provide support to the vascular bifurcation when expanded, the second distal end having a larger diameter than the first proximal end when expanded;

    wherein the plurality of segments consists of four segments and adjacent segments of said four segments are connected to each other by only straight links; and

    wherein one of the single rings is positioned adjacent the second distal end and comprises three and no more than three eyelets integrally formed on a distal end of said single ring, and one of the single rings is positioned adjacent the first proximal end and comprises one and no more than one eyelet integrally formed on a proximal end of said single ring, wherein each eyelet comprises an opening configured to receive a radiopaque marker therein, and the opening is oval in shape and has a circumferential dimension greater than an axial dimension.
