Patent ID: 10314708

Abstract:
An adaptively positioned mitral valve closure plate blocker for repairing mitral regurgitation, comprising a suture and shaping ring (4.1) sutured on a mitral ring (2.1) and a closure plate (4.2); the closing plate (4.2) comprises a tongue-shaped plate and a strut (4.3) located at the top of the tongue-shaped plate and connected to the suture and shaping ring; the closing plate (4.2) can be connected to the suture and shaping ring (4.1), being capable of flapping back and forth and twisting left and right. The suture and shaping ring is sutured on the valve ring (2.1) of the mitral valve (2) of a patient in a thoracotomy and open heart surgery, thus shaping the disease expanded mitral ring (2.1), and supporting the closing plate (4.2); when a heart contracts and valve leaflets close, the closing plate (4.2) flaps and twists depending on the position of a regurgitation opening at the free edge of the valve leaflets to realize adaptive positioning of the closing plate (4.2), so that the closing plate (4.2) is at the free edge when two valve leaflets are closed, covering the regurgitation opening, and is tightly attached to the free edge of the valve leaflets, reducing or avoiding regurgitation of the mitral valve (2).
