This invention relates generally to expandable intraluminal medical devices for use within a body passageway or duct, and more particularly to an optimized stent having asymmetrical strut and loop members. In one embodiment of the invention the stent includes one or more members each having at least one component such as an arc or a strut. The component has non-uniform cross- sections to achieve near-uniform stress distribution along the component when the component undergoes deformation.

L'invention concerne d'une manière générale des dispositifs médicaux intraluminaux extensibles utilisés à l'intérieur de passages ou de conduits corporels, plus précisément une endoprothèse optimisée ayant des éléments supports et boucles asymétriques. Dans un mode de réalisation, l'endoprothèse comporte au moins un élément ayant au moins un composant. Ledit composant présente des sections transversales non uniformes, ce qui permet d'obtenir une distribution de contrainte quasi-uniforme le long du composant lorsque celui-ci subit une déformation.
