Embodiment 1

[0044] The heart valve replacement prosthesis stent of this embodiment includes a sine wave type end-to-end main beam suture frame 1, an upper hook 2 arranged in the sine wave crest of the main beam suture frame 1, and an upper hook 2 arranged on the main beam For the lower hook 3 in the sine wave trough of the suture frame 1, the hooking directions of the upper hook 2 and the lower hook 3 are opposite. In this way, the main beam suture frame 1 is surrounded by a cylindrical frame structure, which can directly act on the aortic valve or pulmonary valve with calcified lesion when it is used for the first time, or can be fixed on the original heart valve by interference extrusion when it is not used for the first time. In the single-layer stent of the replacement prosthesis, or in the inner stent of the double-layer stent of the original heart valve replacement prosthesis, the secondary replacement or repair of the heart valve is completed.

[0045] Refer to attached Figures 1...

Embodiment 2

[0057] This embodiment differs from the first embodiment above in that the shapes of the upper support frame 4 and the lower support frame 5 are different. as attached Figures 11 to 14 As shown, both the lower support frame 5 and the upper support frame 4 in this embodiment adopt a U-shaped structure. Of course, the upper support frame 4 can also adopt X-shaped, diamond-shaped or double-diamond-shaped structures.

[0058] Other structures and manufacturing methods are the same as those of the above-mentioned embodiments, and will not be repeated here.

Embodiment 3

[0060] This embodiment differs from the first embodiment above in that the shapes of the upper support frame 4 and the lower support frame 5 are different. as attached Figures 15 to 18 As shown, in this embodiment, both the lower support frame 5 and the upper support frame 4 adopt a double diamond structure. Of course, the upper support frame 4 can also adopt X-shaped, U-shaped or diamond-shaped structures.

[0061] Other structures and manufacturing methods are the same as those of the above-mentioned embodiments, and will not be repeated here.

Abstract

The invention discloses a heart valve replacement prosthesis and a stent thereof, and belongs to the field of heart valve replacement. The support comprises a sine wave type end-to-end main beam sewing frame, an upper hook arranged in a sine wave crest of the main beam sewing frame and a lower hook arranged in a sine wave trough of the main beam sewing frame, and the hook directions of the upper hook and the lower hook are opposite. A lower supporting frame and an upper supporting frame are arranged in the sine wave crest and the sine wave trough. The main beam suture frame which is connected end to end in a sine wave mode is arranged to form a cylindrical basic framework, and the main beam suture frame can directly act on an aortic valve or a pulmonary valve with calcification lesion through the upper hook and the lower hook which are opposite in hook direction and can also be fixed in a support of an original heart valve replacement prosthesis when not used for the first time. The problem that the existing heart valve cannot be repaired after the first replacement is solved, and the service life of the heart valve replacement prosthesis is greatly prolonged. The stent is high in rigidity, good in shape retention and high in yield.

Description

technical field [0001] The invention relates to the field of heart valve replacement, in particular to a heart valve replacement prosthesis and a bracket thereof. Background technique [0002] Heart valve disease refers to the presence of structural or functional abnormalities in the heart valves, and the disease can involve one or more valves. Among valvular heart diseases in my country, mitral valve disease is the most common, such as mitral valve stenosis, mitral valve insufficiency or mitral valve stenosis combined with regurgitation, followed by aortic valve. The most common degenerative valvular disease in the elderly is the aortic valve disease, such as aortic stenosis, aortic insufficiency or aortic stenosis combined with insufficiency, followed by mitral valve. [0003] Heart valve replacement is a type of surgery for patients with heart valve disease. At present, the main methods are surgical valve replacement and interventional surgery repair or valve replacement...
