ARTIFICIAL MITRAL VALVE INTERVENTION REPLACEMENT DEVICE AND INTERVENTION METHOD THEREOF

摘要

Provided is an artificial valve intervention replacement device applied to mitral insufficiency, comprising a supporting body (1) and artificial valves (2), the lower edge of the supporting body (1) is a conical cylinder structure with a D-shaped cross section, multiple stopping ropes (4) are arranged in the supporting body (1), and the multiple artificial valves (2) are connected to the lower edge and can move along with motion of the natural valve (3) of a patient. The intervention replacement device does not affect the functions of the left chamber outflow channel and the aortic valve, the function of the natural valve (3) of the mitral valve is reserved, the natural blood flow is used for driving the artificial valve (2) and the aortic valve (3) to move in the same direction, and the artificial valve (2) can be completely closed at the contraction period to prevent backflow of the mitral valve.
