  • Patent number: 6497723
    Abstract: The invention relates to a stent for transluminal implantation in a hollow organ, comprising a plurality of circumferentially interconnected stent members forming at least two chains. The chains are linked together via several intermediate members having at least a section disposed at a slant angle relative to the stent longitudinal axis, in order to compensate, at least partly, for the longitudinal shortening upon expansion of the stent. This longitudinal shortening, occurring during stretching of the stent, is reduced owing to the provision, between the chains which are close to the first stent members and linked by intermediate members, of at least one other stent member having a higher elastic deformability than the first stent members.

  • Patent number: 6159237
    Abstract: A vascular or endoluminal stent adapted for deployment in a vessel or tract of a patient to maintain an open lumen therein is formed from a metal open-ended tube which is the single component of the stent. The tube has a multiplicity of holes cut by laser through its wall. The through-holes are encompassed by serpentines that constitute the wall, the serpentines extending sinusoidally each in multiple 360.degree. wavelengths in a single turn about the axis of the tube and juxtaposed in plural substantially identical segments disposed with regularity along the axis. Each segment has a length equal to the distance between crests and troughs of the sinusoid. Adjacent serpentines are joined together at crest and trough, respectively, so that their interconnections are 180.degree. out of phase relative to their wavelength.
