AI Technical Summary

Technical Problem

Existing artificial heart valves are complex and time-consuming when forming and connecting, and are prone to adverse wrinkles during the radial compression and expansion of the valve frame.

Method used

A blade assembly including a plurality of valve blades is adopted, which is connected to the valve frame through a slidable connecting element, ensuring that the height of the valve remains constant during the radial compression and expansion of the frame and avoids radial deformation.

Benefits of technology

The valve formation and connection process is simplified, the operating efficiency is improved, and the valve is maintained in the stable shape during the radial compression and expansion of the frame, reducing the occurrence of adverse wrinkles.

Abstract

The prosthetic heart valve can include an annular frame and a leaflet assembly. The frame can be radially expandable and compressible between a radially compressed state and a radially expanded state. The leaflet assembly can include a plurality of leaflets coupled to one another to form commissures, which can be coupled to the frame using a plurality of commissure linking members. The commissure linking members can be mounted to respective commissure supports for axial sliding movement between the commissure linking members and the commissure support members when the frame is radially compressed and expanded.
