Abstract

A valve leaflet obstruction repair clip and a repair system thereof include a clamping component and a flow obstruction component. The clamping component and the flow obstruction component are assembled and clamped to fix the incomplete closure between the valve leaflets. The upper clamping arm and the lower clamping arm are engaged together in a natural state, and the upper clamping arm undergoes unilateral movement in an extended state. The present application enables edge-to-edge repair of the valve leaflets and adopts unilateral clamping, effectively preventing the problem of valve leaflet stenosis caused by the implantation of the repair device.
