Abstract

The invention discloses an artificial heart valve. The artificial heart valve comprises a bracket, gaskets, valve leaflets, a suture membrane and suture lines; the bracket is in a multilayer reticularstructure; the bracket comprises a blood inflow end and a blood outflow end and is used for supporting and connecting an original heart valve; the gaskets are respectively arranged at the blood outflow ends of the bracket; the valve leaflets are arranged in the blood outflow end of the bracket and are used for replacing original heart valves; the suture membrane is arranged at the inner side andthe outer side of the blood inflow end of the bracket and is used for preventing perivalvular leakage; the bracket is provided with suture holes; the valve leaflets respectively pass through the suture holes and are sutured with the gaskets; and the bracket and the valve leaflets are sutured through the suture lines to form an artificial heart valve structure. The artificial heart valve has high radial supporting force, can reduce the symptom of blood backflow of a patient, and does not easily cause atrioventricular block; the high suture holes reduce the height of the valve membrane, and reduces implant materials; and the problem of postoperative perivalvular leakage can be prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an artificial heart valve. Background technique [0002] The aortic valve is a tri-leaflet valve located between the left ventricular outflow tract and the ascending aorta. The main role of the valve is to maintain efficient left ventricular ejection. Valves are affected in many pathological conditions, with a wide variety of abnormalities. Aortic valve disease is a relatively common disease in the clinical work of cardiologists and cardiac surgeons, mainly because of its high incidence in the elderly. Treatment for severe aortic valve disease includes surgical repair or replacement of the valve. Standard surgical strategies include aortic valve repair, valve protection techniques, and aortic valve replacement techniques. [0003] Aortic valve disease includes aortic stenosis and aortic insufficiency, and in most cases both coexist. Aortic valve stenosis accounts for...
