Valve clip and clipping system thereof

Abstract

The invention relates to a valve clip and a clipping system thereof. The valve clip can be used for effectively treating MR (Mitral Regurgitation) and TR (Tricuspid Regurgitation) after being implanted into the human body by the clipping system. By using the valve clip, the axial operating space of the valve clip can be shortened, and the operating direction can be changed, so that the capturing and clamping operation can be performed from the other side of the valve (i.e., the atrium side) so as to reduce the injury damage on the atrium and the chordae tendineae in the surgical operation process; the length of the valve clip can be shortened, so that the implanted valve clip is shorter so as to reduce the space of the ventricle side occupied by the valve clip, reduce the injury capable ofbeing caused by the valve clip on the heart tissue, and reduce the thrombus forming risk; in addition, after the clipping system passes through the femoral vein and punctures the septum of the rightatrium and the left atrium, the right atrium and the left atrium are used as a delivery path of the clip; the intercostal incision and cardiac apex puncture are not needed; and the surgical trauma issmaller.

Description

technical field [0001] The invention relates to a valve clamp, in particular to a valve clamp and a clamping system thereof. Background technique [0002] The mitral valve is a two-valve valve attached to the periphery of the left atrioventricular orifice (eg figure 1 As shown), it is connected to the papillary muscle by the chordae, which prevents the blood from the left ventricle from flowing back to the left atrium. [0003] Mitral regurgitation (MR) is due to the organic or functional changes in the mitral valve leaflets and their related structures, resulting in poor anastomosis of the anterior and posterior leaflets of the mitral valve, and blood flow back from the left ventricle to the left atrium, causing a series of pathological Physiological changes. Severe MR can cause left ventricular enlargement, and eventually lead to left ventricular systolic failure and heart failure. At the same time, left atrial pressure also increases due to reflux, which can easily lead...

Problems solved by technology

We developed and used this patent, and found through actual surgical operations that the device still has too much operating space to capture the valve, and it can only be operated through the ventricle side (the wound from the apex of the heart is still too large), and it is easy to wind the tendon cable, easy to damage the roof of the atrium, and can only capture defects on both sides of the valve at the same time
