AI Technical Summary
Technical Problem
Incomplete closure caused by too short mitral valve leaves and incomplete closure caused by enlarged valve annulus, which in turn cannot eliminate regurgitation.
Method used
Through the leaflet augmentation enhancement device, artificial leaflets are fixed to the native leaflet using catheters and support arms, and the length of the leaflets is increased by the anchor to solve the problem of incomplete closure.
Benefits of technology
It effectively solves the problem of incomplete closure caused by too short mitral valve leaflets, reduces regurgitation, and improves the function of the leaflets.

Abstract
The invention provides a valve leaflet involution enhancing device which comprises a catheter and a bearing arm, a containing opening is formed in the far end of the catheter, the bearing arm is connected to the catheter, the containing opening is used for containing the bearing arm, the bearing arm has an unfolded state and a closed state, when the bearing arm is in the closed state, the bearing arm is embedded in the containing opening, and the far end of the bearing arm is connected with an artificial valve leaflet. The far end of the bearing arm is used for supporting the native valve leaflet, a puncture channel for the puncture tube to pass through is arranged in the bearing arm, the puncture tube is arranged in the catheter and / or the bearing arm, the puncture tube can puncture the artificial valve leaflet and the native valve leaflet after penetrating out of the puncture channel, an anchoring part is arranged in the puncture tube, and the anchoring part can fixedly connect the artificial valve leaflet and the native valve leaflet. According to the valve leaflet involution enhancing device, the catheter and the bearing arm are arranged, the artificial valve leaflet can be fixed to the original valve leaflet through the anchoring piece in the bearing arm, then the length of the valve leaflet is increased, and the technical problem of incomplete involution caused by the fact that the mitral valve leaflet is too short can be solved.
