A stent with a preferably cylindrical circumferential wall (1) designed as an open, lattice-like, expandable supporting structure with a longitudinal axis (L) is provided, said stent comprising - helix webs (2.1, 2.2, 2.3) running around helically in windings (W) about the longitudinal axis (L) with a helical primary form and a meandering secondary form, which forms meander bends (3.1, 3.2) with a direction of curvature alternating in the circumferential direction (U) and also forms sub-webs (4.1, 4.2) connecting the meander bend (3.1, 3.2), and - connection webs (7) bridging the helix webs (2.1, 2.2, 2.3) of two adjacent windings (W) with a primary direction of extension (H) parallel to the longitudinal axis (L), said connection webs being joined at their sub-web-side ends (8) to adjacent sub-webs (4.1) of the respective helix web (2.1, 2.2, 2.3) and having a flat, zigzag-like shape with two end branches (9.1, 9.2) and an intermediate central branch (10), wherein the end branches (9.1, 9.2) each lead via a termination bend (12) at least approximately at right angles into the respective sub-web (4.1) and the comers in the mouth region (M) between the termination bends (12) and the sub-webs (4.1) are provided with a recess (14). |
