Mitral valve clamp capable of realizing horizontal and vertical clamp and conveyor system

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...

AI Technical Summary

Problems solved by technology

[0005] The structure of the mitral valve clip and its delivery system is extremely complex, and the intervention route; vein-right atrium-left atrium-left ventricle, must puncture the interatrial septum

This is a vertical clipping, the delivery system and interventional surgery are also very complicated, the operation is time-consuming, and the technology is difficult to master

[0006] There are recent patent applications for inventions or utility models in China. The clamping arms are all straight and cannot clamp the leaflets deeply. The leaflets can only be clamped horizontally or vertically. The former is not conducive to preventing the effect of valve edge regurgitation, and the latter It is easy to damage the valve leaflets, which is not conducive to safety and effectiveness.
