Embodiment Construction

[0040] Such as Figure 1 to Figure 10 as shown,

[0041] The invention relates to an aortic sinus aneurysm rupture occluder, which is composed of metal filaments, an impermeable membrane and a fixing element.

[0042] In the existing patients with aortic sinus aneurysm, the rupture of aortic sinus aneurysm will directly cause the defect of aortic valve, threatening the life of the patient. Prompt revision surgery is required for the patient. The current commonly used repair method is: to use the existing vascular occluder to occlude, and this kind of vascular occluder cannot well meet the needs of aortic valve occlusion.

[0043] In view of the existing defects, the subject of protection of this patent is as follows:

[0044] The developed medical device is a medical device for occluding the aortic valve at the rupture of the aortic sinus aneurysm in a manner similar to that of transvenous catheter intervention to occlude the defect of the heart vessel. The element makes t...

Abstract

The invention discloses an occluder for rupture of aortic sinusal aneurysm. A fabric body comprises a circular-arc area, a cylindrical area and a circular disk area, wherein the edge of the circular-arc area is formed by extending out of the outer edge of the cylindrical area by 3-4 millimeters; the cylindrical area is a hollow cylinder of which the diameter is 4-20 millimeters, and the thickness is 2.5-4 millimeters; the circular disk area is a circular flat plate which extends outwards by 0.5-2 millimeters; the closed portion of the fabric body is positioned in the center of the circular disk area and is depressed inwards, and a threaded column is fixed to a recess; expanded films are arranged in the internal cavities of the circular-arc area, the cylindrical area and circular-disk area respectively. The radian of the circular-arc area can be perfectly jointed with one side of an aortic valve, thereby realizing protection in the swinging process of the aortic valve; since the convex edge of the circular disk area is small, a clamping function can be realized; meanwhile, resistance to blood during the flow of blood is reduced as much as possible, and the blood flow smoothness is ensured.

Description

technical field [0001] The invention relates to the field of occluders used in aortic sinus aneurysm rupture closure surgery, in particular to an aortic sinus aneurysm rupture occluder. Background technique [0002] Aortic sinus aneurysm rupture, also known as Valsian sinus aneurysm rupture, is due to the lack of normal elastic tissue and muscle tissue in the aortic sinus wall, which is impacted by high-pressure blood flow and gradually forms a cystic tumor that protrudes outward and eventually ruptures. . This disease is a rare congenital heart disease. The adult incidence rate of this disease is high, and the state of an illness appears suddenly and develops rapidly. The curative effect of the surgery is definite, the mortality rate is low, and the normal heart function can be completely restored after the operation. [0003] During surgery, care should be taken [0004] 1. The aorta and sinus aneurysm break into the cardiac chamber through double incision, and the sin...
