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.
