Beschreibung
Zusammenfassung:	A self-expanding biological valve, comprising a fixed support (1), an inflow end support structure (5), an outflow end support structure (3) and a silica gel suture ring (4). The fixing support (1) comprises a stretching part (2), which is disconnected after being subjected to an expansion force, and then the valve expands at a predetermined position. In an unfolded state, the inflow end support structure (5) and the outflow end support structure (3) extend outwards relative to the fixing support (1) in the radial direction for supporting the valve at the preset position, and continuously applying outward and/or downward force to surrounding tissues, so as to ensure reliable fixation of the valve. The present valve can achieve valve replacement without a complex suture, the operation time is shortened, the risk of complications after operation is reduced. By means of the design, rapid release of the valve support can be achieved, and reliable fixing of the valve support can be achieved.
