A self-expanding stent (10), which is created by laser-cutting a Nitinol alloy tubing. A strut pattern of the stent (10) is formed from a continuous helical band that proceeds circumferentially and longitudinally along the length of the stent (10). The helices are formed by repetitions of sinusoidal forms, with a bridge (12) linking the apexes of struts on neighboring adjacent rows directly opposite of each other, for every 4-8 apexes. The linking bridges are substantially straight such that non off-setting pitches is created at the two connected apexes, resulting in a substantially diamond space (71,72,73) between adjacent rows of the struts, instead of a substantially interdigitated space. The strut repetitions are substantially sinusoidal or in a zigzag fashion. The bridges link the apexes of the repetitions forms directly on adjacent rows of struts. The ends of the stent (10) may be formed by using a transition zone on each end that employs gradually decreasing lengths of struts to complete the transition to an even end. The stent (10) made with this pattern and a suitable material has an optimal combination of torsional flexibility, high radial strength and good resistance to longitudinal compression.Linvention concerne une endoprothèse auto-expansible (10), créée par découpe au laser dune tubulure en alliage de Nitinol. Un modèle dentretoise de lendoprothèse (10) est formé à partir dune bande hélicoïdale continue qui passe, au plan circonférentiel et longitudinal, le long de la longueur de lendoprothèse (10). Les hélices sont formées par répétitions de formes sinusoïdales, avec un pont (12) qui relie les sommets des entretoises sur des rangées voisines adjacentes, directement opposées les unes aux autres, tous les 4 à 8 sommets. Les ponts de liaison sont sensiblement droits, de sorte que des pas de décalage soient créés au niveau des deux sommets connectés, ce qui crée un espace sensiblement en forme de losange (71, 72, 73) entre des rangées adjacentes des ent
