1. A prosthetic tricuspid annuloplasty ring, comprising:

  • a ring body generally arranged about a flow axis along an inflow-outflow direction, the ring body being overall convex and asymmetric in plan view looking along the axis and having at least three inflection points around the ring periphery in plan view and extending around the periphery in a single elongated member without branches and lying generally perpendicular to the axis, wherein the ring is configured to contact and support the interior of the tricuspid annulus, and defines in plan view, in sequence, a first free end, a first septal segment, an anterior segment adapted to attach to the tricuspid annulus adjacent the anterior leaflet and spanning an equivalent peripheral distance, a posterior segment adapted to attach to the tricuspid annulus adjacent the posterior leaflet and spanning an equivalent peripheral distance, and a second septal segment adapted to attach to the tricuspid annulus adjacent the septal leaflet, wherein each of the anterior, posterior and second septal segments is generally concave inward, and a second free end separated across a gap from the first free end such that the ring is discontinuous, and wherein two of the inflection points are in the anterior segment.
