Membrane coating stent for aortic arch part integral three-branch endovascular repair treatment

The utility model relates to a membrane coating stent for aortic arch part integral three-branch endovascular repair treatment. The membrane coating stent for theaortic arch part integral three-branch endovascular repair treatment is composed of a first naked multi-waveform columnar single-ring, a second multi-waveform columnar single-ring covered by a tubular membrane and third multi-waveform columnar single-rings. A wedge-shaped groove is arranged on the membrane coating stent among the third multi-waveform columnar single-rings from the first one to the fifth one, and a straight-branch stent, a first sloped-branch stent and a second sloped-branch stent are arranged in the wedge-shaped groove. Blood flow channels of the aortic arch brachiocephalic trunk, the left carotid artery and the left subclavian artery are reserved by using a three-branch stent in the wedge-shaped groove, and release position of the three-branch stent is designed in the aortic arch part blood vessel. The membrane coating stent for the
