Abstract
Implant for improving coaptation of an atrioventricular valve in a human heart, the atrioventricular valve having a first and a second native leaflet, an anterolateral and posteromedial commissure between the first and the second native leaflet, and an annulus adjacent a wall of an atrium of the heart. The implant including a frame that includes a middle frame section that frames and supports an artificial central leaflet. The artificial central leaflet is configured to cover a middle region of the first native leaflet. The middle frame section includes a bend formed between a first region of the artificial central leaflet and a second region of the artificial central leaflet that forms a coaptation plane for coaptation with the second native leaflet. The frame further including two side frame sections extending at opposite sides of the middle frame section and configured to contact side regions of the first native leaflet.
