Abstract
(EN)
[Problem] To affix an intersection section of a stent. [Solution] A stent in which a plurality of element wires are spirally interwoven, wherein two intersecting element wires are affixed by an affixing material having rubber elasticity in a section in which the element wires intersect.
(FR)
Le problème décrit par la présente invention est de fixer une section d'intersection d'un stent. La solution selon l'invention porte sur un stent dans lequel une pluralité de fils d'élément sont entrelacés en spirale, deux fils d'élément d'intersection étant fixés par un matériau de fixation ayant une élasticité de caoutchouc dans une section dans laquelle les fils d'élément se croisent.
