A prosthetic valve, solving the technical problem of an existing prosthetic valve, when implanted in a certain valve site, not being adaptive to the physiological anatomy condition of the heart, being difficult to mount and fix properly and being easy to become displaced, and consequently affecting the function of the valve. The prosthetic valve comprises an annular frame () which has a mesh structure and can radially expand to deform; a connection line () is provided on the frame (); the prosthetic valve is connected and fixed to an anatomical structure of a mounting position of a human body by means of the connection line (); the connection line () surrounds the outside of the frame () to form several connection portions which extend out along the radial direction of the frame (); the space surrounded by the connection portions can receive the thickness of the anatomical structure. The prosthetic valve is connected and fixed by means of the connection line () to an anatomical structure of a mounting position in a human body, e.g. a vessel wall, being mounted stably and being applicable to a patient on whom a valve replacement surgery is difficult to perform, e.g. a pulmonary artery stenosis patient.

Prosthetic valve and prosthetic valve implanting method

A device for treating regurgitation of a tricuspid valve (). The device comprises a tricuspid valve plug () capable of compressing and expanding and a tricuspid valve plug fixing device used for anchoring the tricuspid valve plug () to an orifice of the tricuspid valve (). The tricuspid valve plug () is provided with an inflow end () and an opposite outflow end (), and a prosthetic valve () capable of being opened and closed is disposed in the tricuspid valve plug (). When the tricuspid valve () is closed, the prosthetic valve () is automatically closed, and when the tricuspid valve () is opened, the prosthetic valve () is automatically opened. The device for treating regurgitation of a tricuspid valve () and the implantation method therefor help to treat regurgitation of a tricuspid valve and do not block the flow of blood in a heart, and the device can be recycled, has the characteristics of high operationality and high safety in minimally-invasive repair, and has high clinical value.

Artificial heart valve

A device for treating regurgitation of a tricuspid valve () is disclosed. The device comprises a tricuspid valve plug () capable of compressing and expanding and a tricuspid valve plug fixing device used for anchoring the tricuspid valve-in-plug () to an orifice of the tricuspid valve (). The tricuspid valve plug () is provided with an inflow end () and an opposite outflow end (), and a prosthetic valve () capable of being opened and closed is disposed in the tricuspid valve plug (). When the tricuspid valve () is dosed, the prosthetic valve () is automatically closed, and when the tricuspid valve () is opened, the prosthetic valve () is automatically opened.
