St. Jude Medical has launched its Attune flexible adjustable annuloplasty ring for the repair of diseased heart valves in the U.S. The company received FDA clearance and introduced the product at the annual meeting of the American Association for Thoracic Surgery in Boston on May 9.
The mitral valve controls the flow of oxygenated blood between the upper and lower chambers of the heart, according to the St. Paul, Minn.-based company. When a mitral valve malfunctions due to infection, MI damage, a congenital condition or other cause, the valve no longer closes tightly because its leaflets become misaligned, allowing blood to regurgitate, or leak backward.
The Attune ring is a flexible annuloplasty ring designed to support a repair of the heart's mitral valve. The ring allows the annulus to continue its natural movement as the valve opens and closes, thus contributing to more physiologic valve function. The ability to adjust the ring post-implant promotes ideal leaflet alignment to reduce or eliminate residual regurgitation, or small leaks after the repair.
