Problems solved by technology

[0002] Aortic valve stenosis is one of the most common adult valvular diseases. The most effective way to treat aortic valve stenosis is to install an artificial stent in the aortic valve stenosis. The traditional artificial stent has implantation and installation during the installation process. Inconvenient and risky during the installation process, which is not conducive to the rapid, efficient and safe implantation and installation of artificial stents

Abstract

The invention discloses a trans-catheter implanted artificial aortic valve stent and a delivery system thereof. The artificial aortic valve stent comprises a stent unit and supporting airbags; the stent unit includes a main supporting network pipe, connecting network pipes and auxiliary supporting network pipes; the connecting network pipes are distributed at two ends of the main supporting network pipe; the auxiliary supporting network pipes are distributed at the ends, away from the main supporting network pipe, of the connecting network pipes; ring surfaces formed by the main supporting network pipes and the auxiliary supporting network pipes at opposite sides of ring surfaces formed by the connecting network pipes are concave; the supporting airbags penetrate through the stent unit; the front end of each supporting airbag is provided with an opening and is connected with a mounting shell head, and the rear end of each supporting airbag is provided with an opening and is connected with an air tube; and the end, away from the supporting airbag, of the air tube is provided with a detachable air sealing nozzle. During application of the artificial aortic valve stent, the artificialaortic valve stent can be quickly and safely transplanted to an aortic valve stenosis position through the delivery system, and the difficulty of implantation is reduced, thus being beneficial to realizing rapid, efficient and safe implantation installation of the entire artificial aortic valve stent.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an artificial aortic valve stent implanted through a catheter and a delivery system thereof. Background technique [0002] Aortic valve stenosis is one of the most common adult valve diseases. The most effective way to treat aortic valve stenosis is to install an artificial stent in the place of aortic valve stenosis. The traditional artificial stent has implantation and installation during the installation process. It is inconvenient and the risk in the installation process is relatively high, which is not conducive to the rapid, efficient and safe implantation and installation of the artificial stent. To this end, we propose a transcatheter implanted aortic valve stent and its delivery system. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a transcatheter-implanted artificial aortic v...
