The invention belongs to the technical field of medical instruments, and particularly relates to a blood vessel inner false lumen blocking stent, comprising a stent body, a distal choke membrane, a proximal choke membrane, two circumferential blocking membranes, a release nut and a fixed bushing. The stent body is an expandable net body knitted by nickel-titanium alloy wire, and 2 to 4 layers of distal choke membrane are parallel mutually and are mounted inside the distal end of the stent body at intervals, thus, the multiple layers of distal choke membrane are used for preventing backflow ofdistal break blood; 2 to 4 layers of proximal choke membranes are parallel mutually and are mounted inside the proximal end of the stent body at intervals; the outer surfaces of two ends of the stentbody are covered with two circumferential blocking membranes circumferentially. The stent has excellent deformability and flexibility, good anchoring effect, cannot fall to aorta true lumen, can effectively prevent aorta distal break blood from flowing back to the false lumen, and is favorable for thrombus formation of the false lumen and remodeling of the true lumen.
