Cardiac valve annulus reduction system
First Claim
1. A device for treating mitral valve regurgitation, comprising:
- a tubular member being sufficiently flexible to be transformable between a relatively straight delivery configuration and a deployed ring shape approximating the size and shape of a mitral valve annulus, the tubular member having a through lumen and a plurality of sidewall openings generally disposed around a perimeter of the deployed ring shape; and
a barb assembly comprising a filament extending through the lumen and a plurality of self-extendible barbs coupled to the filament and corresponding to the sidewall openings, the barb assembly being slidable within the lumen to align the barbs with the corresponding sidewall openings to permit self-extension of the barbs there through;
wherein the tubular member has a plurality of protruding anchors generally disposed around a perimeter of the deployed ring shape.

Abstract
A catheter-based, annulus reduction device and system for cardiac valve repair and method of using the same. The system is usable for treating mitral valve regurgitation and comprises a catheter, a reduction ring carried within the catheter, the reduction ring including a plurality of exit ports formed in a side wall of the reduction ring and filament received in the reduction ring. The filament includes a plurality of radially extendible barbs corresponding to the sidewall openings. The reduction ring carrying the filament is deployed adjacent a mitral valve annulus and the filament is translated relative to the reduction ring to deploy the barbs through the exit ports and into the annulus and to further translate the reduction ring with deployed barbs to reshape the annulus.
