Single-side branch stent-graft with ring

The utility model discloses a single-side branch stent-graft with a ring. The single-side branch stent-graft comprises a film-coated stent-graft, wherein the film-coated stent-graft consists of a metal stent made from a cobalt-chromium-nickel-molybdenum-iron alloy and a film coating made from polyester; a single-side branch vascular graft made from polyester is arranged at one end of the film-coated stent-graft; a vascular ring made from the cobalt-chromium-nickel-molybdenum-iron alloy is arranged at a middle joint with the single-side branch vascular graft on the film-coated stent-graft. The single-side branch stent-graft has the beneficial effects that the vascular ring is arranged, so that suture is not required in an operation, and operation time is greatly saved; an operation and circulation arresting process can be finished within 1 minute, the distal port anastomosis of the artery under deep hypothermic circulatory arrest in a conventional total aortic arch replacement and stent elephant trunk method is replaced, and by the step, the hemoperfusion of the head and systemic circulation is recovered.
