HEART VALVE ANCHORING MECHANISM AND HEART VALVE PROSTHESIS DEVICE

WIPO Patent Application WO/2022/166062

A1

A heart valve anchoring mechanism (220) and a heart valve prosthesis (100) device. An end of a heart valve is provided with a connector (210) extending in an axial direction; and the anchoring mechanism (220) is configured to be fixed to an end of the connector (210), and comprises a spacer (221) and an anchoring member, with the spacer (221) comprising a first surface (2211) attached to tissue and a second surface (2212) opposite the first surface (2211), and the anchoring member comprising a plurality of anchoring units (222). The plurality of anchoring units (222) of the anchoring member are respectively attached and anchored to the tissue, and are also attached to the surface of the tissue by means of one surface of the spacer (221); the spacer (221) can provide a relatively large surface area, such that stress concentration can be prevented, and thus preventing the tissue from being worn by the anchoring member; in addition, when the anchoring units (222) are attached to the tissue, an action force is generated for the spacer (221), which action force can make the spacer (221) tightly attach to the tissue, thereby realizing the effects of sealing a wound and enhancing the anchoring, and the matching between the spacer (221) and the anchoring units (222) can provide a better anchoring effect.
