Abstract
An elastically curved suture anchor is resiliently straightened and delivered into tissue by a needle. When the needle is withdrawn, resumption of the curvature provides leverage for anchor rotation as the attached suture is pulled to fasten the anchor within the tissue. A fin at the proximal end of the anchor further increases the rotational leverage and expedites anchor fastening. When two or more anchors with connecting suture are delivered in series on a needle, the tension of the suture helps to draw the anchors together and approximates the pierced tissue.
