Title: ADAPTIVE HEART VALVE PROSTHESIS
Abstract:
An adaptive heart valve prosthesis (100, 200, 300, 400, 500), comprising a stent (110, 210, 310) and a prosthetic valve (120, 520); the stent comprises a leak-proof ring (111, 211, 311, 411, 511) and a valve seaming section (112, 212, 312, 412, 512, 612), the leak-proof ring (111, 211, 311, 411, 511) and the valve seaming section (112, 212, 312, 412, 512, 612) are connected to each other; the prosthetic valve (120, 520) is fixedly connected to the valve seaming section (112, 212, 312, 412, 512, 612), at least a part of the valve seaming section (112, 212, 312, 412, 512, 612) is positioned between self-body heart valve leaves of a patient, on a cross section perpendicular to a central axis of the prosthetic valve (120, 520); the cross-sectional area of the valve seaming section (112, 212, 312, 412, 512, 612) is smaller than the cross-sectional area of a self-body heart valve ring of the patient, such that the valve seaming section (112, 212, 312, 412, 512, 612) does not directly radially expand the self-body heart valve ring of the patient; in a free state, the cross-sectional area of ​​the leak-proof ring (111, 211, 311, 411, 511) is larger than the cross-sectional area of ​​the self-body heart valve ring of the patient, and the leak-proof ring (111, 211, 311, 411, 511) can conform to the uneven contour of an atrial chamber wall or the self-body heart valve ring of the patient.
