  • a thin, tubular member, the thin tubular memberbeing cut from a seamless, thin-walled metal tube in such a manner that two axially outer, and one or more axially inner, expandable rings of net-like or meander-like webs result, any two adjacent rings being interconnected with each other by only a pair of stretchable connecting webs curved in the axial direction of the tubular member with the stretchable connecting webs of the pair being angularly offset from each in a first radial direction at an angle of less than 180°

    , having a first diameter for the intraluminal conveyance of the tubular member, which may be expanded to a variable second diameter by exerting a radial, outwardly directed force from inside the tubular member, and which is inserted into the blood vessel by means of a balloon-tipped catheter and expanded therein, and wherein connecting web pairs succeeding each other in the axial direction being disposed angularly offset with respect to the preceding ones.
