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 segmen ts (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 transfe r sections (8). Adjacent ring segments (3-5) are coupled to each other using connecting brac es (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), th e segmented braces (6, 7) being curved in an wavelike manner. |
