Abstract
An anti-thrombotic and endothelialization-enhanced bioprosthetic valve material and preparation thereof are provided. The preparation method includes the following steps: immersing a glutaraldehyde cross-linked bioprosthetic valve material in functional reagent solution for 1-24 h, adjusting pH value of the solution to 3-8, removing it from solution and cleaning with deionized water. The new valve material of the present invention can effectively reduce the toxicity and side effects of the existing glutaraldehyde cross-linked bioprosthetic valve material and effectively reduce thrombosis, along with enhanced endothelialization. The material prepared can be used for pulmonary valve, aortic valve, mitral valve, tricuspid valve, venous valve and other cardiovascular implantable medical devices.
