The stent (1) is a vascular prosthesis for a narrowed body vessel. The stent (1) has a tubular support frame (2) consisting of a plurality of axially continuous ring segments (3, 4, 5). These ring segments (3, 4, 5) are formed from segment struts (6, 7) which are connected to each other via a transition section (8) in the starting state in an endless manner. Adjacent ring segments (3-5) are joined by connector struts (9, 10). In order to avoid the notch stress in the segment struts (6, 7), the width of the segment struts (6, 7) is changed from the central region (16) of the segment struts (6, 7) to the transition section (8). Has been expanded towards. In this configuration, the segment struts (6, 7) are curved into a waveform. |
