摘要:
The invention relates to a stent comprising terminal anchoring elements. Said stent (10) is provided with a tubular wall that extends along a longitudinal, flexible tubular axis (26), is formed from a flexible grid structure, and has tube ends (20) lying on opposing axis ends. Said wall consists of annular wall segments (11) that are lined up along the axis and are interconnected by means of connection segments (12). The annular wall segments (11) contain wall elements (14, 15) having an elastic structure. The inventive stent is characterized in that the wall comprises a flexible, arched anchoring element (22) on at least one tube end (20, 20′), said anchoring element being connected to at least two terminal wall elements (14, 15, 14′, 15′) in such a way as to form one component, bridging at least one elastic wall element (14, 15), and there is a larger radial distance between the ogive (24) of the arched anchoring element (22) and the tubular axis (26) than between the terminal wall elements (14, 15) and the tubular axis.
