The invention relates to an annuloplasty device for use on a posterior annulus of a mitral valve, including at least a first and a second anchor unit, preferably a plurality of anchor units, that are deployable to the mitral valve by means of a vascular delivery device, such as a catheter, and positionable in a row along the annulus, including anchor means arranged on each of the first and second anchor units, wherein the first and second anchor units are interconnected by connection means defining a distance between the first and second anchor units, further including pulling means for reducing the distance between the first and second anchor units so as to pull the annulus together, wherein the anchor units are arranged to be rotatable to one another around a longitudinal axis extending along the row.
