The present invention refers to a tubular support prostheses (stent) for vessels or intercorporeal lumina comprising at least two adjacently arranged expandable support rings connected to one another on at least one joint, said support rings being formed by a filament wound in a meander-like manner to form several arcs of curvature. The expansion behavior of such a support prosthesis is to be improved. For this purpose at least one arc of curvature of a first support ring and an arc of curvature of an adjacent second support ring overlap laterally, whereby the joint in the overlapping portion is formed.
La présente invention se rapporte à une prothèse de soutien tubulaire (endoprothèse) pour les vaisseaux sanguins ou autres conduits intracorporels comprenant au moins deux anneaux de soutien extensibles disposés de manière adjacente l'un par rapport à l'autre, les anneaux étant en outre raccordés l'un à l'autre en au moins un point de jonction. Ces anneaux de soutien sont formés d'un filament enroulé en méandre pour former plusieurs courbes arquées. La caractéristique d'extension de cette prothèse de support reste à améliorer. € cette fin, au moins une courbe arquée du premier anneau de support et une courbe arquée du second anneau adjacent se chevauchent latéralement; c'est dans ce chevauchement que se forme la jonction.
