Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
113 words
Tubular member (1) for an intraluminal endoprosthesis, of the type which is obtained by cutting from a tube and which can be expanded by application of a force, comprising longitudinal portions (2, 22, 32) which are connected in pairs successively by at least one transverse portion (3, 23, 33) having the same thickness as the longitudinal portions and a width less than the longitudinal portions, characterized in that the said transverse portion comprises at least one undulation which is deformable during expansion of the member, this deformable undulation being provided in such a way that the deformation of the transverse portions has an effect exclusively on the radial dimension of the tubular member.
