Medtronic‘s newly announced CG Future® COMPOSITE Annuloplasty Ring has been designed to accommodate the dynamic nature of transmitral flows:
The new CG Future COMPOSITE Ring is the industry’s first annuloplasty product providing both semi-rigid posterior remodeling and fully flexible anterior support, thereby allowing physiologic movement throughout the cardiac cycle.
“The CG Future COMPOSITE Ring offers the flexibility of a band and the confidence of a ring,” said Oern Stuge, M.D., president of the Cardiac Surgery business at Medtronic. “This one-of-a-kind product was created with the patient and their implanting surgeon in mind. The composite design offers semi-rigid remodeling of the posterior portion of the mitral annulus with flexibility across the anterior, both of which are important in helping return patients to a normal functioning mitral valve after their surgery.”
When functioning normally, the dome-shaped mitral valve controls blood flow from the lungs, closing tightly under the pressure of freshly oxygenated blood when the heart contracts, then opening when the heart relaxes. Blood then flows into the left ventricle, the heart’s main pumping chamber, where it is pumped throughout the body’s circulatory system with the next heartbeat…
During mitral valve repair, the surgeon seeks to restore, or “remodel,” a narrowed, prolapsed or leaking valve to a more-normal shape and leaflet alignment, thus restoring its functionality. The new Medtronic CG Future® COMPOSITE Annuloplasty Ring incorporates a flexible anterior segment seamlessly connected to a semi-rigid posterior metal portion. The composite design is engineered to support and hold the rear of the valve in alignment while allowing optimum physiological movement for the front of the valve throughout the cardiac cycle. The radiopaque device’s firm, yet flexible, construction combines with its low bulk, low profile, and innovative anchoring eyelets designed for strength and predictable, time-efficient implantation.
