| description | The invention discloses a self-expanding double-layer tower type covered stent and a delivery device thereof. Compared with a traditional covered stent, the double-layer tower-shaped covered stent has the advantages that the effect of isolating an aneurysm cavity is enhanced by adding a layer of covered structure, the burr structure capable of inducing thrombus is arranged on the covered film between the double-layer tower-shaped covered structure, thrombus formation can be quickly induced, and the thrombus formed through induction can be quickly released. According to the invention, reflux blood from the external iliac artery and (or) internal iliac artery can be further blocked, and finally, the purposes of avoiding extending a far-end anchoring area of the EVAR to the external iliac artery, improving the isolation efficiency of an aneurysm cavity, reducing post-operation Ib type internal leakage, avoiding gluteus ischemia and pelvic organ ischemia and increasing the treatment success rate are achieved.
