AI Technical Summary

Technical Problem

In existing technologies, the anchoring methods for artificial heart valves are prone to damaging the native leaflets or compressing the native annulus. Furthermore, the anchoring ring delivery system is complex, increasing the difficulty and time of the surgery and affecting the patient's health.

Method used

Design a valve anchor, including an elastic wire, a receiving part, and a traction body, capable of switching between contraction and expansion states, controlling the direction of movement of the anchor through the traction body, simplifying the implantation process, avoiding damage to the native valve leaflet, and adapting to the external contour of the artificial heart valve during expansion.

Benefits of technology

It simplifies the implantation process of valve anchors, reduces the difficulty of the surgery, improves the success rate of artificial heart valve implantation, reduces harm to patients, and enhances the reliability and safety of the surgery.

Abstract

The application provides a valve anchor and a valve system, the valve anchor comprising an elastic wire, a containing part and a traction body; the containing part is arranged outside the elastic wire and connected with the elastic wire; the containing part is distributed along the extension direction of the elastic wire and has a cavity; the traction body is partially arranged in the cavity of the containing part, and after being wound into a closed loop at the end of the containing part corresponding to the distal end of the elastic wire, the traction body is divided into two parts, the two parts extend along the axis of the containing part in the containing part, and the two ends of the traction body extend out of the containing part at the end of the containing part corresponding to the proximal end of the elastic wire; the traction body can be pulled to control the moving direction of the distal end of the valve anchor. The application can make the valve anchor precisely surround the native valve leaflet under the cooperation of the elastic wire and the traction body, thereby simplifying the implantation step of the valve anchor and reducing the implantation difficulty.
