    摘要： A stent configured to closely contact tissue in vivo by being deformed when set indwelling in vivo. The stent has a plurality of axially arranged annular members, with axially adjacent annular members being interconnected by at least one link part; and a metallic wavy-linear annular member positioned at each end of the stent. The plurality of axially arranged annular members include a plurality of linear components, the linear components including a plurality of metallic linear components and a plurality of biodegradable material-made linear components. The at least one link part is defined by one of the metallic linear components. After a predetermined period of time when the stent is left indwelling in vivo and biodegradation of the biodegradable material-made linear components proceeds, the plurality of metallic linear components and the at least one link part remain intact such that a unitary metallic structure is maintained in vivo.

    摘要： 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.
