Abstract

The invention discloses a bicuspid valve clip. The bicuspid valve clip includes two first sheet members, two second sheet members, and a central portion; one end of two ends of each first sheet memberis connected to the central portion; one end of two ends of each second sheet member is connected to the central portion; the two first sheet members can be opened and closed with respect to the central portion at the same time; the two second sheet members can be opened and closed with respect to the central portion at the same time; and when the two first sheet members and the two second sheetmembers are opened at the same time, the two first sheet members are position on the same direction of the two second sheet members, and the first sheet members and the second sheet members can form aclamping structure. The bicuspid valve clip can enter a heart through a catheter, can achieve a clamping structure between the first sheet members and the second sheet members, can clamp a bicuspid valve which cannot be closed normally, and can prevent mitral regurgitation.

Description

technical field [0001] The invention relates to a mitral valve clip. Background technique [0002] With the advent of population aging, the incidence of heart valve disease has increased significantly. The traditional treatment for mitral valve regurgitation is valve repair or valve replacement. However, due to the large surgical injury and many related complications, many elderly patients with severe valvular disease cannot receive treatment. In recent years, surgical treatment of valvular heart disease has gradually become minimally invasive. Interventional treatment of valvular heart disease has developed rapidly due to its advantages of less trauma, relative safety, and good curative effect. The curative effect of treatment is more certain, and some new technologies have become new hotspots in interventional cardiology research. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heart mitral valve clamp that...
