Abstract
A radially expandable stent for implantation within a body vessel, comprising a first and second elongated element having a series of peaks alternating with valleys forming a wave shape therein. The first elongated element is interwoven with the second elongated element in a series of crossovers, with each crossover forming a symmetrical intersection and each successive pair of crossovers defining a loop. The interwoven first and second elongated elements are wound into a hollow cylindrical shape with at least one longitudinal strut extending parallel to a longitudinal axis of the hollow cylindrical shape and passing through at least one of the loops along the hollow cylindrical shape.
