ABSTRACT:
A self-expanding stent is proposed for hollow organs for the bracing and/or for the holding open of a hollow organ. The stent comprises two bands 11 which span a tubular and self-expanding network. The network is stretched in an axial direction in a collapsed state of the lumen and, in an expanded state of the lumen, is foreshortened in an axial direction and the network comprises at least two bands 11. In accordance with the invention, each individual band 11 is fashioned from at least two filaments 13 which run parallel to each other, which are connected to each other in a point-like fashion, and which interlock at crossing regions 12.
