Stent graft

Stent graft comprising a stent (1) having a plurality of ring segments (3) the ring segments having a meandering pattern and being arranged side by side, adjacent ring segments (3) being connected with each other by connecting webs (7), the stent graft further comprising at least one membrane (2), characterized in that a plurality of connecting webs (7) between two adjacent ring segments (3) are provided with flexible tongues (6), which are arranged in a form-closed manner in the connecting webs (7) and which are resiliently movable with respect to the connecting webs (7), wherein the at least one membrane (2) is clamped between the flexible tongues (6) and the connecting webs (7), and wherein at least one of the two adjacent ring segments (3) between which the connecting webs with flexible tongues extend has freely ending webs which are aligned in parallel to the flexible tongues and are arranged at turning points of the at least one of the two adjacent ring segments, each of the freely ending webs (9) projecting into a gap between two connecting webs (7), said freely ending webs (9) serving to additionally secure the at least one membrane (2).
