Abstract

The invention provides a mitral valve clip, comprising a lock ring and also comprising a first anti-thrombus mesh sleeve that is made of memory alloy; the lock ring is sleeved with the first anti-thrombus mesh sleeve. As the first anti-thrombus mesh sleeve is provided in the mitral valve clip provided herein, thrombi are decreased; after thrombi are formed, the first anti-thrombus mesh sleeve is removed and replaced with a new first anti-thrombus mesh sleeve; therefore, the service life of the mitral valve clip is extended.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a mitral valve clamp. Background technique [0002] The mitral valve is two valves located on the periphery of the left atrium and ventricle. It is connected to the papillary muscle by the chordae and prevents the blood from the left ventricle from flowing back to the left atrium. 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 to left atrial enlargement, atrial fibril...
