Abstract:
1. A stent having a length and a plurality of interconnected circumferential bands, each circumferential band having a plurality of interconnected struts formed in a serpentine pattern, each of the plurality of interconnected struts having a length and a width as measured along the surface of the stent and a thickness as measured in a radial direction, the interconnected struts comprise longer struts and shorter struts, the longer struts and shorter struts being alternatingly arranged in a circumferential direction about the stent, the longer and the shorter struts being substantially parallel to a longitudinal axis of the stent, the interconnected struts further comprising joining struts, the joining struts having one of a first slant direction relative to the longitudinal axis and a second slant direction relative to the longitudinal axis that is different from the first slant direction, the first and second slant directions alternating along the length of the stent, the circumferential bands including a plurality of first circumferential bands and a plurality of second circumferential bands, the plurality of second circumferential bands having fewer circumferential bands than the plurality of first circumferential bands, the interconnected struts of the second circumferential bands being wider than the interconnected struts of the first circumferential bands, the width of the interconnected struts in each first circumferential band being the same width and the width of the interconnected struts in each second circumferential band being the same width, wherein one of the plurality of second circumferential bands forms one end of the stent, each second circumferential band is engaged only to one or two first circumferential bands and adjacent circumferential bands are engaged by a plurality of connector struts.
