Bioprosthetic valve and preparation method thereof |
| abstract |
A bioprosthetic valve and a preparation method thereof are provided. The bioprosthetic valve includes a stent and a functional biological tissue material attached to the stent. The functional biological tissue material is a biologicaltissue covalently bonded with an active group and a functional molecule or group. The method improves the anti-thrombosis and anti-calcification functions by covalently modifying the surface of a biological valve using an active group and a functional molecule or group with a substantial degree of grafting. The new bioprosthetic valve does not include aldehyde residues, exhibits excellent biocompatibility, optimal mechanical properties, high stability, and can meet the performance requirements of a biological valve delivered through a catheter. |
