The Rigid Saddle Ring with EZ Suture™ Cuff from St. Jude Medical™, is the first choice for mitral annulus remodeling. The unique and durable design mimics natural anatomy. According to clinical studies, healthy mitral annuli are shaped like a saddle. The unique saddle shape of the Rigid Saddle Ring ensures efficient distribution of chordal tension and leaflet stress, unlike rigid rings that are used traditionally. The St. Jude Rigid Saddle Ring, with a complete core made of titanium alloy, is a saddle-shaped three-dimensional ring that maintains the anatomical shape of a mitral annulus, with a height-to-width ratio of 15%. The double-velour cuff made of polyester double-velour encourages tissue in-growth.
