Abstract
Implantable devices and methods for the repair of a defective cardiac valve are provided. The implantable devices include an annuloplasty ring and a restraining and/or a remodeling structure or mechanism. The annuloplasty ring functions to reestablish the normal size and shape of the annulus bringing the leaflet in proximity to each other. A device having a remodeling structure further facilitates remodeling of the valve but allows the use of a flexible ring. The restraining structure functions to restrain the abnormal motion of at least a portion of the valve being repaired. The restraining and remodeling structures may include at least one strut across the interior of the circumference of the ring.
