Abstract: A prosthetic valve, solving the technical problem of an existing prosthetic valve, when implanted in a certain valve site, not being adaptive to the physiological anatomy condition of the heart, being difficult to mount and fix properly and being easy to become displaced, and consequently affecting the function of the valve. The prosthetic valve comprises an annular frame (2) which has a mesh structure and can radially expand to deform; a connection line (10) is provided on the frame (2); the prosthetic valve is connected and fixed to an anatomical structure of a mounting position of a human body by means of the connection line (10); the connection line (10) surrounds the outside of the frame (2) to form several connection portions which extend out along the radial direction of the frame (2); the space surrounded by the connection portions can receive the thickness of the anatomical structure.

Abstract: A transapically-implanted mitral valve flexible closure plate blocking body comprising: a flexible closure plate (7), a left and right guide wire (8), a guide ring (13) and a fixation plug (12). The fixation plug (12) is fixedly implanted at a cardiac apex (4) of the heart, the flexible closure plate (7) is located at an anterior and posterior leaflet junction of the heart, the left and right guide wire (8) respectively pass through a hook (6) on the same side, are fixedly connected to the flexible closure plate (7) in the upper portion on the same side, and respectively pass through a guide ring (13) fixedly connected in the lower portion of the flexible closure plate (7) on the same side, and are fixedly connected to the fixation plug (12). An implantation method thereof is also provided.

Abstract: A device for treating regurgitation of a tricuspid valve (4) is disclosed. The device comprises a tricuspid valve plug (21) capable of compressing and expanding and a tricuspid valve plug fixing device used for anchoring the tricuspid valve-in-plug (21) to an orifice of the tricuspid valve (4). The tricuspid valve plug (21) is provided with an inflow end (42, 52) and an opposite outflow end (47, 57), and a prosthetic valve (50, 70) capable of being opened and closed is disposed in the tricuspid valve plug (21). When the tricuspid valve (4) is dosed, the prosthetic valve (50, 70) is automatically closed, and when the tricuspid valve (4) is opened, the prosthetic valve (50, 70) is automatically opened.

Abstract: A device for treatment of valve regurgitation is described, comprising frameworks (114, 133, 141, 701, 812, 821, 911) and an anchoring unit (132). The anchoring unit (132) is connected to the frameworks (114, 133, 141, 701, 812, 821, 911); the frameworks (114, 133, 141, 701, 812, 821, 911) can be expanded and compressed and have an inflow end (421) and an opposite outflow end (422); valve leaflets (142, 621, 721, 751) capable of opening and closing in blood flow are provided inside the frameworks (114, 133, 141, 701, 812, 821, 911); the anchoring unit (132) can keep the frameworks (114, 133, 141, 701, 812, 821, 911) in an expanded state at the orifice position of a natural heart valve. The device for treatment of valve regurgitation and an implantation method therefor can effectively treat valve regurgitation.
