The invention relates to a stent with a substantially tubular body which can be converted from a compressed state with a first cross-sectional diameter into an expanded state with an enlarged second cross-sectional diameter. The stent comprises at least two support portions (12) and at least one connecting portion (14) which follow one another in the longitudinal direction of the stent. Each support portion has multiple openings (16) in the wall of the tubular body and border elements (18) which are formed by the tubular body and which surround the openings and together with said openings form support portion cells (20) in the expanded state. Two support portions which are adjacent to each other in the longitudinal direction are connected via a connecting portion lying between said support portions, and each of the mutually facing end faces (28) of the adjacent support portions are formed by a row (22) of end-face cells of the respective support portion. The connecting portion comprises one or more connecting elements which are formed by the tubular body and which connect the mutually facing end faces of the two adjacent support portions, and only some of the cells which form one of the two mutually facing end faces of the adjacent support portions are directly connected to the other of the two mutually facing end faces of the adjacent support portions via a connecting element. |
