Contour 3D™ Annuloplasty Ring for Surgical Valve Repair

The Contour 3D annuloplasty ring is a remodeling ring with a physiologic tricuspid valve shape — a 2-D shape and 3-D curvature based on CT data from functional tricuspid valves.

See Tricuspid Clinical Evidence


2-D Shape 3-D Curvature  

The Contour 3D annuloplasty ring is a three-dimensional, anatomically shaped rigid remodeling ring for the treatment of functional tricuspid valve disease. The ring is designed to facilitate an asymmetric reduction annuloplasty.

Product Details

The Contour 3D design is based on CT data from functional human tricuspid valves.

Rings that resemble the natural shape of the annulus provide better leaflet coaptation than planar rings by preserving greater leaflet mobility.1,2

Septal lateral compression is incorporated into the ring to address annular dilatation.
