Annuloplasty rings for repairing cardiac valves
First Claim
1. An implantable device for repairing a mitral valve having an annulus, multiple leaflets and a subvalvular apparatus, comprising:
- a band configured for placement in a coronary sinus adjacent to the valve annulus, and having an interior pathway within at least a portion of the band;
a plurality of openings positioned along a side of the band in spaced relation to one another, the openings being in communication with the interior pathway; and
at least one restraining strut extending from within the interior pathway of the band through at least one of the openings in a substantially transverse orientation with respect to the band and shaped to extend from at least one of the openings, through the coronary sinus wall, over a leaflet of the mitral valve and toward the left ventricle to restrain prolapsing of the valve leaflet.

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.
