STENT AND SECURELY-INSTALLED ARTIFICIAL VALVE REPLACEMENT DEVICE HAVING SAME |
摘要 |
A stent and a securely-installed artificial valve replacement device having the same, the stent being of a cylindrical structure; the top of the stent is provided with a fixed ear (60); the fixed ear (60) has a neck portion (601) connected to the top of the stent, and a head portion (602) engaged with the fixed head of the stent; the head portion (602) has a bending structure for improving the overall radial thickness; and the artificial valve replacement device is comprised of a stent and a prosthetic valve fixed on the stent. The stent with a bending structure overcomes the problem of easily disengaging from the fixed head of the stent, while not affecting the release of the stent. |
