Abstract: An implant for improving coaptation of an atrioventricular valve in a heart, the atrioventricular valve having a native first leaflet, a native second leaflet and optionally an annulus adjacent a wall of an atrium of the heart, the implant comprising an artificial leaflet to replace or support the first and/or second native leaflets, fixing means for fixing the implant to the annulus or to the first and/or second native leaflets and retention means for preventing prolapse of the artificial leaflet. The retention means comprise or consist of a backbone element extending along the artificial leaflet and towards a distal end of the artificial leaflet and being connected to the artificial leaflet at at least two attachment points, wherein the backbone element is configured to be bendable between first and second states of bending and wherein limiting means are provided for limiting the degree of bending.

Abstract: Annuloplasty device for use on a posterior annulus of a mitral valve, which is deployable to the mitral valve by means of a vascular delivery device, such as a catheter, and positionable along the curvature of the annulus, including at least a first and a second branch, each configured to extend along at least a section of the annulus, with a first end and a second end, at least one guiding means for guiding the first and the second branches relative to one another, at least one fixing means for fixing the device to the annulus, and at least one anchor means arranged on each of the first and second branches, whereby the first and the second branches are movable relatively to one another, so that the anchor means engage with the annulus thereby pulling the annulus together when the first and second branches are moved in opposite directions.
