Title:
HEART VALVE
Document Type and Number:
WIPO Patent Application WO/2022/141789
Kind Code:
A1
Abstract:
An at least partially degradable heart valve, wherein by setting the heart valve to be at least partially degradable, a degradable part of the heart valve can be selected according to the actual application scenario, and the size of the part is gradually reduced until it is completely degraded and disappeared. In practical applications, a heart valve can be tightly connected and fixed by means of an endothelialized density and a primary tissue. In this way, the obstruction of the outflow tract can be effectively reduced, and the influence on the hemodynamics is reduced, so that the occurrence probability of thrombi and hemolysis is avoided.
