Leaflet augmentation device

By using the clamping components and puncture structure of the leaflet enhancement device, the problem of unstable adhesion between the original leaflet and the lateral area of ​​the artificial leaflet is solved, resulting in better leaflet closure, reducing the possibility of blood backflow, and improving the outcome of cardiac valve repair surgery.

AI Technical Summary

Technical Problem

In existing heart valve repair surgeries, the lateral areas of the original leaflet and the artificial leaflet cannot fit stably, which increases the likelihood of blood backflow.

Method used

The device employs a leaflet enhancement mechanism, which uses a clamping assembly to stably hold the original leaflet. A puncture structure is used to puncture and connect the original and artificial leaflets in the middle region. The fixing components of the fixing structure cover the middle region of the artificial leaflet and extend to the side region to provide support and ensure stable fit.

Benefits of technology

It reduces the likelihood of separation between the original leaflet and the lateral region of the artificial leaflet during blood flow impact, improves the stability of leaflet closure, and enhances the effectiveness of cardiac valve repair surgery.

Abstract

The application belongs to the technical field of medical devices, and particularly relates to a leaflet reinforcing device, which comprises a catheter component, a clamping assembly, a puncture structure and a fixing structure. The clamping assembly is used for clamping a native leaflet. The fixing structure comprises a fixing member, and the fixing member comprises a first part. The first part is fixed on an artificial leaflet, covers a middle area of the artificial leaflet, and extends to side edge areas on both sides of the artificial leaflet along a width direction of the artificial leaflet. A buckling member of the puncture structure is used for puncturing a middle area of an overlapping part connecting the native leaflet and the artificial leaflet. The technical scheme is applied to solve the problem that the side edge areas of the native leaflet and the artificial leaflet cannot be stably attached after a heart valve leaflet repair surgery, which may cause blood reflux.
