Abstract: The present application discloses at least an artificial heart valve prosthesis anchoring device comprising a memory metal wire, wherein the memory metal wire is bent and encircled to form a closed loop configured to anchor an artificial heart valve stent, and the closed loop comprises: at least two clamping portions configured to form an expansion force in a radial direction and a restraint force in a circumferential direction to anchor the anchoring device between a heart valve and an adjacent blood vessel wall; and connecting portions that quantitatively correspond to the clamping portions, are alternately arranged with the clamping portions, and are used for transition and connection of adjacent clamping portions.
