Abstract
Abstract An apparatus, system, and method for repairing openings such as septal defects includes advancing a catheter to the site of the defect, grasping opposing edges of the defect, passing one or more suture lines through the opposing edges, tightening the suture lines, and deploying and expanding a fastener to secure the suture lines and close the defect. The fastener can include tissue-growth-inducing materials to encourage tissue growth onto or into the fastener and/or suture. The fastener includes a locking clip portion and a plug portion, which may be an expandable portion and/or tissue-growth-inducing portion.
