ABSTRACT:
A vascular endoprosthesis intended to maintain the walls of anatomic channels. The endoprosthesis is formed by a combination of longitudinal juxtaposed unitary assemblies (1) having flexible, elastic longitudinal ribs (3, 4, 5) connected to each other by transverse strands (2) which are also flexible and elastic and are fastened on an intermediate rib (3) in such a manner as to form "V's" with the intermediate rib (3). The combination forms a herringbone structure, the assembly of which by juxtaposition with other such assemblies forms an openwork cylinder (53).
