Abstract:
1. An annuloplasty ring for implanting adjacent to the annulus of a tricuspid valve, the valve comprising anterior, posterior and septal leaflets and the annulus comprising an anteroseptal commissure between the anterior and septal leaflets, a posteroseptal commissure between the posterior and septal leaflets, an anteroposterior commissure between the anterior and posterior leaflets, an anterior annular portion adjacent to the anterior leaflet, a posterior annular portion adjacent to the posterior leaflet, and a septal annular portion adjacent to the septal leaflet, with blood flowing in a downward direction though the valve, the ring comprising: a first segment for implantation adjacent to the anterior annular portion curved away from a bottom plane, having a second segment for implantation adjacent to the posterior annular portion, continuous at a first end with the second end of the first segment, having a second end for implantation adjacent to the posteroseptal commissure and intersecting the bottom plane parallel to the top and middle planes; a third segment for implantation adjacent to the septal annular portion curved away from the bottom plane, continuous at a first end with the second end of the second segment, having a second free end for implantation adjacent to the anteroseptal commissure of the annulus and intersecting with the top plane; whereby the top plane is offset above the middle plane, the bottom plane is offset below the middle plane as oriented by the flow of the blood, the ring has a gap between the first free end of the first segment and second free end of the third segment and, the ring may be implanted adjacent to a tricuspid valve.
