Method of repairing a defective heart valve

A method of repairing a defective heart valve comprising;

• directing an implant delivery catheter to form a first curve of the implant delivery catheter around chordae of the heart valve on a ventricular side of the heart valve,
• forming a second curve of the delivery catheter along an annulus of the heart valve on the atrial side so that the first curve and the second curve form a helix shape with two continuously connected loops, on opposite sides of the heart valve, being connected through a commissure of the heart valve,
• aligning the first and second curve of the delivery catheter generally in the plane 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 ventricular and atrial side and positioned generally in said plane when retracting the delivery catheter,
• wherein the annuloplasty implant has a predefined ring-shape having a curvature corresponding substantially to the first and second curve, such that, when ejected from the delivery catheter, the annuloplasty implant is arranged along the first and second curve,
• wherein the predefined ring-shape is a helix-shaped ring, whereby a first support ring of the helix-shaped ring is positioned on the atrial side and a second support ring of the helix-shaped ring is positioned on the opposite ventricular side when ejecting the annuloplasty implant from the delivery catheter while retracting the delivery catheter, whereby leaflets of the heart valve are pinched between the first and second support rings.
