Problems solved by technology

During the operation, the transapical path is usually taken, and the turning of the mitral valve is difficult and difficult to operate due to its large size. Therefore, the metal frame used in the product needs to be very light and thin, but due to its large size, it bears more stress , insufficient durability, prone to breakage or displacement

Abstract

The invention provides a mitral valve forming ring for intervention. The mitral valve forming ring comprises a metal frame with a D-shaped section, the metal frame can expand or contract in the radial direction, and the metal frame is divided into a supporting section and an anchoring section which are in butt joint along the edge; after the mitral valve forming ring is implanted into the body, the supporting section is located in the left atrium, and the anchoring section is located in the left ventricle; and in the direction from the left ventricle to the left atrium, the supporting section is of an expansion-reducing structure; anchoring parts are arranged on the outer circumferential wall and the inner circumferential wall of the anchoring section. According to the mitral valve forming ring, the metal frame is designed to be provided with the D-shaped section, the anchoring parts are arranged on the outer circumferential wall and the inner circumferential wall of the anchoring section respectively, the external anchoring parts enable the mitral valve forming ring not to be prone to displacement after being released, and the internal anchoring parts can provide positioning and supporting for a subsequent percutaneous catheter mitral valve replacement valve so as to achieve a better treatment effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a mitral annulus forming ring available for intervention. Background technique [0002] The human heart has four chambers and four valves, which control the direction of blood flow. Fully functioning heart valves ensure that normal blood circulation is maintained during the cardiac cycle. Heart valve regurgitation or leaks can occur when the leaflets of the heart valve do not close adequately due to disorders such as congenital valvular insufficiency, torn chordae, stretched chordae, enlarged left ventricle, damaged papillary muscle, and Structural damage to the valve caused by infection, degenerative changes, calcification of the valve leaflets, stretching of the valve annulus, or widening of the papillary muscle spacing. Regardless of the cause, valvular regurgitation interferes with heart function because it allows blood to flow back through the valve in the wrong direc...
