1. A stent, particularly a coronary stent, comprising at least one thin-walled, tubular element, the generated surface of which is in the form of an open network and has apertures bounded by narrow, strap-like elements, the strap-like elements being formed from the remaining material of the tubular wall from which the material in the area of the apertures was removed, characterised in that pairs of transversely expandable elements are directly joined at the ends longitudinally of the stent, each of the two expandable elements, in the form of a flattened ring element made up of straps, being joined transversely by a strap-like element to another transversely expandable element, which is itself not directly joined at the end to another expandable element, which is in turn joined by a strap-like element to one of the first-mentioned, transversely expandable elements, the strap-like elements each being inclined to the transverse direction at an angle such that this angle is reduced on expansion of the stent, and the non-joined adjacent ends of transversely expandable elements thus move away from each other.
