Abstract: A clamp includes upper clamp assemblies, lower clamp assemblies, a base, a locking unit, a connecting rod arm, expandable arms and a central occluding woven net. The upper clamp assemblies and the lower clamp assemblies are quantitatively identical and cooperate in opening and closing to form a clamping portion. The clamp can effectively occlude the regurgitation on two sides of the clamp through the expandable arms on the two sides. By means of the central occluding woven net, the clamp can further reduce the central regurgitation, decrease the stress on the leaflet and prevent the damage to the leaflet; and the clamp firmly closes the lower clamp assemblies in a mechanical locking manner, such that the clamp does not drop easily after implanted into the body. The clamp can be implanted through the femoral vein puncture and transseptal puncture (TSP) with minimal invasion, to repair the mitral valve.

Abstract: The present invention discloses a novel valve clamping device and a valve clamping system. The valve clamping device includes a first clamping component, a second clamping component, and a fixing component for fixing the first clamping component and the second clamping component. The first clamping component has at least two first clamping arms. The second clamping component has a corresponding number of second clamping arms. Each of the first clamping arms and the corresponding second clamping arm may be combined into a pair of clamps. The clamping device may adopt designs of a smooth transition at the top, the clamping teeth having high clamping stability, and the fixed ring achieving the purpose of “one thread for two uses”.
