Annuloplasty device

An annuloplasty device comprising:

• A first support ring and a second support ring having a coiled configuration in which the first and second support rings are arranged as a coil around a central axis, the central axis extending in an axial direction from the second support ring to the first support ring, wherein:
• the first and second support rings are configured to be arranged on opposite sides of native heart valve leaflets of a heart valve,
• the first support ring is adapted to be arranged on an atrial side of said heart valve and the second support ring is adapted to be arranged on a ventricular side of the heart valve,
• the first support ring comprises a first posterior bow and a first anterior portion,
• the second support ring comprises a second posterior bow and a second anterior portion,
• the first and second posterior bows are adapted to conform to a posterior aspect of said heart valve and the first and second anterior portions are adapted to conform to an anterior aspect of said heart valve,
• the first support ring transitions to the second support ring over a transition section adapted to be arranged at a commissure of the heart valve leaflets,
• the first posterior bow of the first support ring and the second posterior bow of the second support ring extend in respective first and second coil planes being perpendicular to the central axis,
• the transition section bends at least partly along the central axis so that the first coil plane is separated a distance (d1) from the second coil plane along the central axis at the transition section,
• a tilted section of the first anterior portion raises above the first posterior bow in the axial direction,
• the tilted section raises to an apex of maximum separation from the first posterior bow along the axial direction, and
• the apex directly transitions into the transition section.
