Disclosed is a stent (1) representing a prosthesis for a constricted body vessel. Said stent (1) comprises a tubular support frame (2) composed of ring segments (3, 4, 5) which succeed each other in an axial direction and are formed by segmented braces (5, 6) that are continuously joined to one another in the neutral state via transfer sections (8). Adjacent ring segments (3-5) are coupled to each other using connecting braces (9, 10). In order to prevent notch stress in the segmented braces (5, 6), the width thereof increases from the central zone (16) in the direction of the transfer sections (8), the segmented braces (6, 7) being curved in an wavelike manner.

L'invention concerne un tuteur intravasculaire (1) qui constitue une prothèse vasculaire pour un vaisseau rétréci. Le tuteur intravasculaire (1) comprend une ossature support (2) tubulaire, à base de segments annulaires (3, 4, 5) successifs dans le sens axial, qui se composent, à l'état initial, d'entretoises segmentées (5, 6) se jouxtant en continu par l'intermédiaire de sections de transition (8). Des segments annulaires adjacents (3 à 5) sont accouplés par des entretoises de connexion (9, 10). Afin d'éviter des phénomènes d'entaille en fatigue dans les entretoises segmentées (5, 6), la largeur desdites entretoises augmente dans chaque cas à partir de leur zone médiane (16), en direction des sections de transition (8). A cet effet, les entretoises segmentées (6, 7) sont cintrées de manière ondulée.
