Aortic Stent Graft with Chimney Stent Support Tube

The invention discloses an aorta covered stent with a chimney stent supporting pipe. The aorta covered stent comprises a main stent, at least one supporting pipe for releasing a chimney stent is arranged in the main stent, arranged close to the front end of the main stent and tightly and fixedly connected with the inner wall of the main stent, and the wall of the main stent is provided with a through hole communicated with the supporting pipe. By means of the aorta covered stent of the structure, the at least one supporting pipe is reserved in the aorta covered stent, after the aorta covered stent is released and attached to the wall, the chimney stent is then released by the reserved supporting pipe into important branch blood vessels, and blood flow supplying to the important branch blood vessels is accordingly guaranteed. Due to the fact that the chimney stent is released to the inner side of the aorta covered stent, wall attaching of the aorta covered stent cannot be influenced, and inner leakage can be accordingly and effectively avoided; in addition, the aorta covered stent cannot press the chimney stent, and decreasing of cross sections of blood flow channels or blocking of the blood flow channels formed by the chimney stent can be effectively avoided.
