Embodiment Construction

[0052] See attached figure 1 - attached Figure 8 , the horizontal and vertical mitral valve clip of the present invention includes the implementation of the upper and lower valve clips, the vertical arm clip and the components of the delivery system, showing the specific structure and its key connections. How to achieve horizontal and vertical anastomosis can effectively prevent two cusp regurgitation.

[0053] Refer to attached figure 1 The upper valve clip 1 of the mitral valve clip is provided with the clip arm 1-1 that is symmetrically strip-shaped straight neck section and arc section, and the butting surface of the clip arm can be provided with convex nail 1-2, and the clip arm root can be thinned. It is elastically deformed and connected to the rectangular sheet-shaped socket section 1-3, and the lower end of the lower flap jacket stage corresponding to the two sides is provided with a spring clip 1-4, and the lower part is a sliding section 1-5, and the tail section...

Abstract

The invention discloses a mitral valve clamp capable of realizing horizontal and vertical clamp and a conveyor system. A main body of the system comprises the mitral valve clamp capable of realizing horizontal and vertical clamp and a conveyor; the mitral valve clamp is composed of an upper valve clamp member, a lower valve clamp member and a vertical arm clamp member; a clamp arm of the mitral valve clamp includes a straight neck section and an arc section, and vertical and horizontal anastomosis or clamping two clamp valve leaflets can be formed under assisted clamp of a vertical arm clamp;and the conveyor is composed of an outer push-pull tube, a vertical arm clamp push tube, a clamp tube or a screw rod and a sheath tube, the conveyor components support the mitral valve clamp and are put in the sheath tube, the conveyor realizes minimally invasive intervention from a chest and the tip of a heart, and can clamp mitral valve leaflets horizontally and vertically and effectively prevent backflow.

Description

[0001] field of invention [0002] The invention belongs to the field of implanted medical devices, in particular to a mitral valve clamp and a delivery system for horizontal and vertical clamping, which are used for treating heart mitral valve regurgitation. Background technique [0003] Cardiac mitral regurgitation can cause heart failure. Seriously, it can cause death. It is estimated that there are nearly ten million patients with mitral regurgitation in China. Surgical treatment is performed for patients, and edge-to-edge sutures and suture ring implantation are mostly used. Surgical operations require thoracotomy, large surgical trauma, high cost, slow recovery, and high surgical mortality for elderly and seriously ill patients. [0004] Inspired by the treatment of mitral regurgitation by the double border suture of the mitral valve margin, Mitra Clap was invented abroad in the early years to intervene in the mitral valve clip and delivery system for the treatment of...
