  • METHOD FOR CROSSLINKING ARTIFICIAL BIOLOGICAL TISSUE
    Publication number: 20200147265
    Abstract: The present disclosure provides a method for crosslinking an artificial biological tissue. The method may include: providing an artificial biological tissue and crosslinking agent solution, wherein the crosslinking agent includes an imide structure; immersing the artificial biological tissue into the crosslinking agent solution to produce a crosslinking reaction. In this way, the anti-calcification capacity of the crosslinked artificial biological tissue may be improved in the present disclosure.

  • PROSTHETIC TISSUE VALVE AND METHOD OF PREPARING THE SAME
    Publication number: 20200147268
    Abstract: The present disclosure provides a prosthetic tissue valve and a preparation method thereof. The preparation method consists of a lyophilization process of soaked biological tissues under preset condition to obtain a lyophilized prosthetic tissue valve, which provides a technical support for pre-loading the lyophilized prosthetic tissue valve onto the delivery device immediately after manufacture. The preset conditions may include a cooling process with a cooling rate of which the temperature decreases from room temperature to a lyophilization temperature, the lyophilization temperature of ?200° C.-0° C., and a pressure of 1 Pa-102 kPa. In such a way of preparation, the present disclosure can provide a lyophilized prosthetic tissue valve.
