The invention relates to a stent graft comprising a stent () having a plurality of ring segments () disposed adjacent to one another and connected to one another and at least one membrane () having at least one marginal ring segment () having a meandering web configuration, wherein web loops () which point inwards or outwards are cut in such a way as to produce spring tabs () which are disposed so that they engage positively in the web loops () and are resiliently movable against the web configuration, wherein the membrane () is gripped between the spring tabs () and the web.

Stent graft

A medical implant for the expansion and support of a body vessel is formed as elongate struts in a shape of a tube. The struts are plastically deformable at least in sections so that the implant remains permanently expanded in the radial direction transversely to a longitudinal axis of the struts in the expanded state. A course of the expandable element has a plurality of direction changes with respect to the longitudinal axis. The expandable element has a constriction point in the contracted state designed as an intended breaking point for the expandable element. The constriction point breaks upon application of excessive force applied in the radial direction preventing further expansion of the expandable element.
