Integrated multi-branched stent graft aortic arch intervention

The present invention discloses an integrated multi-branched stent graft aortic arch involved, the stent-graft is a crank-shaped structure includes a front bow region, a rear region and a bow Bow: the bow section of the front region of the tubular film along one end thereof extension forming a coating film by an end region of the bow before the start arcuate bent portion extending arch region is formed, the film is formed continues to extend from the rear end region of the bow region of the bow portion; large curvature region of the bow portion ellipsoidal projection, in fixing projection is provided with a branch and the brachiocephalic trunk body with fixed aperture disposed successively on a side branch of the artery with two left common carotid artery and the left subclavian; are fixing film and the branch liner has coating a plurality of rows for supporting and fixing the metal frame branches. Advantage of the present invention is capable of anatomically characteristic aortic arch, by using a combination of different types of activities and branch stent body frame, completely cover the body of the aortic arch, aortic protect, continued expansion and prevention of rupture of a blood vessel.
