摘要： An implantable valved stent for a patient's heart is formed by a stent supporting a cloth structure. The valved stent includes an upper mounting portion and a lower valved portion. The upper mounting portion has an upper side and a lower side supporting a plurality of hooks extending downwardly from the lower side whereby the implantable valved stent is mounted to the heart when heart tissue is captured between the hooks and the lower side. The lower valved portion extends downwardly from the upper mounting portion and includes a check valve that allows downward flow of the blood and checks upward flow of blood.

摘要： A prosthetic tissue valve and a method of treating the prosthetic tissue valve are provided. The method includes: decreasing a temperature of a chamber carrying the prosthetic tissue valve from a first preset temperature to a second preset temperature in a first cooling rate (S102); decreasing the temperature of the chamber carrying the prosthetic tissue valve from the second preset temperature to a third preset temperature in a second cooling rate (S102); and performing a drying process to the prosthetic tissue valve (S103). The second preset temperature is a critical crystallization temperature and is greater than a crystallization temperature of the prosthetic tissue valve. The third preset temperature is lower than the crystallization temperature of the prosthetic tissue valve, and the second cooling rate is greater than the first cooling rate.
