Methods for Anchoring Suture and Approximating Tissue

摘要

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 When the needle is withdrawn, resumption of the curvature provides leverage for anchor rotation as the attached suture is pulled to fasten the anchor within the tissue.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.

主权项

1. A method for delivering a suture anchor within tissue of a patient, the method comprising the steps of:
(a) puncturing the tissue with a needle, carrying a suture anchor; (b) removing the needle from the suture anchor; (c) and pulling a suture connected to the suture anchor causing a fin on the suture anchor to snag the surrounding tissue, thereby causing said suture anchor to rotate within tissue.
