The invention relates to an implant having an openwork, hollow-cylindrical main body (10), which is assembled from a plurality of openwork, hollow-cylindrical segments (11,13), which are arranged in succession in the longitudinal direction (L) and which are connected to one another. The segments each comprise a terminal segment (11) at each end of the main body (10) arranged in the longitudinal direction and at least one inner segment (13), which is arranged in the longitudinal direction (L) between the two terminal segments (11), wherein each segment (11, 13) has a plurality of bars (21), which together form a meandering structure with maximum points (25) and minimum points (23) which runs around in the circumferential direction. The main body (10) assumes a compressed state and an expanded state. The meandering structure of at least one terminal segment (11) has a smaller number of maximum points (25) and minimum points (23) than the at least one inner segment (13), and the inner or outer diameter of this at least one terminal segment (11) in the compressed state or in the expanded state is substantially the same as the inner or outer diameter of the at least one inner segment (13) in the same state.L'invention concerne un implant comportant un corps principal (10), ajouré et cylindrique creux, qui est assemblé à partir d'une pluralité de segments (11,13) cylindriques creux ajourés, qui sont disposés en succession dans la direction longitudinale (L) et qui sont reliés les uns aux autres. Les segments comprennent chacun un segment terminal (11) à chaque extrémité du corps principal (10) disposé dans la direction longitudinale et au moins un segment interne (13), qui est agencé dans la direction longitudinale (L) entre les deux segments terminaux (11), chaque segment (11, 13) présentant une pluralité de barres (21) qui forment ensemble une structure formant des méandres avec des points maximaux (25) et des points minimaux (23) qui s'étendent dans la direction circon
