1. A method for repairing a defective heart valve, said method comprising:
directing a delivery catheter to form a first curve of the delivery catheter around the heart valve at a first side of native heart valve leaflets thereof;
forming a second curve of the delivery catheter around the heart valve on a second side of the native heart valve leaflets opposite the first side, the first and second curves being connected through a commissure of the heart valve; and
ejecting an annuloplasty implant from the delivery catheter while retracting the delivery catheter such that the annuloplasty implant is arranged along the first and second curve on the first and second sides,
whereby retention units of the annuloplasty implant are engaged into tissue of the heart valve from the first side and the second side when the delivery catheter is retracted and wherein
the first side is a ventricular side of the heart valve and the second side is an atrial side of the heart valve;
the first curve of the implant delivery catheter is arranged around chordae of the heart valve on the ventricular side; and
the second curve of the delivery catheter is arranged along an annulus of the heart valve on the atrial side.
