Problems solved by technology

[0006] In the prior art, the structural design of the biological valve is unreasonable; especially the structure is complex. During the interventional operation, the diameter of the interventional catheter required is relatively large, which is likely to cause secondary damage to the patient's blood vessels and reduce the success rate of the operation.

Abstract

The invention discloses a balloon-expendable transcatheter valve. According to the balloon-expendable transcatheter valve, a lower end of the prosthetic heart valve is fixedly connected with a fixingring; and a side part of the prosthetic heart valve is fixedly connected with a support frame. A fixing mesh frame is arranged, close to an inner cavity, on one sides of a supporting ring and a connecting mesh frame. The fixing mesh frame is fixedly connected with an inner wall of the supporting ring; the prosthetic heart valve is clipped between the connecting mesh frame and the connecting mesh frame; and a bottom binding wire is arranged in such a way that the bottom binding wire penetrates through the fixing mesh frame, the prosthetic heart valve and the connecting mesh frame, thereby allowing bound connection between the fixing mesh frame, the prosthetic heart valve and the connecting mesh frame. The balloon-expendable transcatheter valve is simple in structure and feasible for furtherreduction of compression diameter, thereby allowing catheter diameter reduction during an interventional surgery. Moreover, doctor can adjust degree of valve obstruction during use of the valve according to different medical records of patients, thereby achieving the best obstruction intensity for the patients so as to improve patient comfort; and blood pressure on the valve can also be reduced so as to ensure service life of the valve.

Description

technical field [0001] The invention relates to the technical field of structural design of artificial bioprosthetic heart valves used in heart medical treatment, in particular to a balloon-expandable transcatheter valve. Background technique [0002] Artificial heart valve (Heart Valve Prothesis) is an artificial organ that can be implanted in the heart to replace the heart valve (aortic valve, tricuspid valve, or mitral valve), which enables blood to flow in one direction and has the function of a natural heart valve. When the heart valve disease is too serious to recover or improve the function of the valve by valve separation surgery or repair surgery, artificial heart valve replacement must be used. Valve replacement cases mainly include rheumatic heart disease, congenital heart disease, and Marfan syndrome. [0003] With the advancement of science and technology, artificial heart valves have experienced the evolution process of spherical valve, single-leaf disc valve,...
