A strut, or beam, is provided for intraluminal devices. Strain which is introduced into a stent or other intraluminal device is distributed more evenly along the length of the improved strut by maintaining a substantially constant strain level along the length of an end portion. This may increase fatigue life or improve the performance of devices using the improved strut. The strain along the length of the end portion may be maintained substantially constant by varying a section property of the strut, including the width, thickness, cross-sectional area, material property or other characteristic of the end portion.
La présente invention concerne une poutre destinée à des dispositifs intraluminaux. La contrainte exercée sur une endoprothèse ou tout autre dispositif intraluminal est répartie régulièrement sur la longueur de la poutre par le maintien d~un niveau de contrainte sensiblement identique sur la longueur d~une partie terminale. Cela peut augmenter la durée de vie ou l~efficacité des dispositifs employant des poutres perfectionnées. La contrainte le long de la partie terminale peut être rendue sensiblement constante en faisant varier les propriétés de ladite contrainte, telles que la largeur, l~épaisseur, la section transversale, les propriétés matérielles ou tout autre caractéristique de la partie terminale.
