A stent (1) is a vascular prosthesis for a constricted body vessel. The sten t (1) comprises a tubular supporting structure (2) consisting of annular segments (3, 4, 5), which follow one another in an axial manner and which, i n an initial state, are formed from segment braces (6, 7) continuously joined to another via transition sections (8, 9). Adjacent annular segments (3-5) are linked by connector braces (10). The segment braces (6, 7) are curved in a wave-like manner. Each front transition section (8) on at least one annular segment (3), which is located at the end with regard to longitudinal axis (L ), has an axially protruding widened head end (22, 23). Head ends (22, 23) that are adjacent in the peripheral direction (U) are offset from one another alo ng the longitudinal axis (L) of the stent and are connected to the adjacent annular segment (4) via connector braces (10). Each connector brace (10) comprises a wave-like curved axial section (11) and a V-shaped compensating section (12) oriented in the peripheral direction (U) of the supporting structure (2). |
