Bioprosthetic heart valves and production methods

The present invention discloses a bioprosthetic heart valve and manufacturing method thereof. The bioprosthetic heart valve comprising a valve frame, a valve leaflet and an auxiliary structure, which is connected to the valve leaflet auxiliary structure, the auxiliary valve flap is connected to the frame structure, and the auxiliary structure and the valve leaflets are made of biological material. Flap holder are integrally made of elastic material, and the valve is preset identification sewn secondary structure. Bioprosthetic heart valves of the present invention, increases biocompatibility with the human body, reducing the overall height of the valve, reducing the sewing time, reduces the probability of thrombi or bacteria adhering thereto, and the production process is simple, and the cardiac tissue compliance, extended the life of the valve.
