The suturing means comprise a suturing ring (20), from which at least one suturing member (21) extends radially in order to penetrate the vessel wall. On at least the first outer end the tubular body (10) is double-walled, with an inner wall (11) and an outer wall (12) between which the suturing ring (20) lies enclosed. The suturing ring preferably comprises three such suturing members (21) and a closing ring (40) is arranged locally round the vessel.
