artificial heart valvuloplasty ring

Abstract

The invention relates to an artificial cardiac valve forming ring. The artificial cardiac valve forming ring comprises a support body, wherein the support body comprises a tube-shaped main body with aplurality of plate strips, each plate strip is of a non-linear structure, a through groove is formed between each two adjacent plate strips, and each through groove extends to the other end of the main body from one end of the main body. For the artificial cardiac valve forming ring, the support body comprises the tube-shaped main body with the plurality of plate strips, each plate strip is of anon-linear structure, during the heartbeat period, the plate strips can have deformation along with the movement of the heart, so that the perimeter of the forming ring changes therewith, the area ofthe valve opening also changes therewith, thus the free movement rule of the valve ring is adapted, and finally, the influences of the forming ring on the left heart function are reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an artificial heart valve forming ring. Background technique [0002] The human heart has four heart valves: the mitral, tricuspid, aortic, and pulmonary valves. Take the mitral valve as an example. The mitral valve is located between the left atrium and the left ventricle and acts as a one-way valve. During a cardiac cycle, when the left atrium contracts, the mitral valve opens, and blood flows from the left atrium to the left ventricle; when the left ventricle contracts, the mitral valve closes, and blood is pumped from the left ventricle to the whole body. [0003] When there is a disease of the mitral valve, such as an enlarged valve ring, that is, when the left ventricle contracts, the mitral valve cannot be completely closed, causing part of the blood to flow through the mitral valve to the left atrium, and there is a phenomenon of blood backflow, commonly known as the mitra...

AI Technical Summary

Problems solved by technology

After the plastic ring with this design structure is implanted in the heart, the shape of the plastic ring will change with the size of the valve ring during the heart motion cycle, but the area of ​​the valve opening will remain constant because of the area of ​​the plastic ring on it. It is kept constant and cannot meet the changing requirements of the valve area, thus affecting the natural movement of the valve ring and affecting the left heart function
