Abstract

The annuloplasty is in the form of an open or partly enclosed ring (1) with gap. The ring has a core made of metal or a metal alloy, preferably titanium with different flexibility on the ring's plane according to sectors. The core is more flexible in the middle part (4) and near the valve area (2). The core has differently profiled sectors (2,3,4) along its length. The ring is curved forwards in the direction of blood flow.
