Mitral valve forming ring with coating base material

Abstract

The invention discloses a mitral valve forming ring with a coating base material, which comprises a forming ring body and the coating base material, the forming ring body comprises a plurality of contraction joints with a soft structure, and the plurality of contraction joints can be connected end to end to form an annular structure; the wrapping base material comprises a nickel-titanium alloy net wrapping the surface of each contraction joint, and each nickel-titanium alloy net comprises a wrapping section wrapping the surface of the corresponding contraction joint and an extending section which is connected to the wrapping section and extends outwards in the direction away from the center of the annular structure. The nickel-titanium alloy net is arranged on each contraction joint, and each nickel-titanium alloy net comprises a wrapping section wrapping the surface of the corresponding contraction joint and an extending section which is connected to the wrapping section and extends outwards in the direction opposite to the center of the annular structure of the forming ring, so that shaping during release of the forming ring and compactness of attachment of the forming ring and the autologous valve leaflet are guaranteed, and recycling is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mitral annulus forming ring with a covering base material. Background technique [0002] The mitral valve is located on the left side of the heart, between the left atrium and left ventricle. The most typical disease of the mitral valve is regurgitation, or regurgitation, which occurs when the valve leaflets do not coapt properly. Mitral valve repair by suturing the annulus to reduce the annular diameter is the procedure of choice for correction of mitral cardiac regurgitation. With current surgical techniques, most regurgitant mitral valves can be repaired or replaced with prosthetic valve repair. [0003] Most current surgical practice for mitral valve repair involves mitral annuloplasty and or valruloplasty. [0004] The existing mitral annuloplasty generally integrates rivet-like elements on the forming ring, ① resulting in a large diameter when the forming ring ...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the large diameter of the delivery system of the forming ring integrated with rivets in the prior art, the inconvenience of recovery, the shaping of the forming ring and the bonding with the native valve leaflet when the forming ring is released. interfering defects, thereby providing a mitral annuloplasty ring with a covering substrate
