Abstract
The present invention is directed to a method of securing suture within a patient. The method comprises advancing suture material into the patient, passing a portion of the suture material through tissue of the patient, and advancing a fastener catheter and a suture fastener along the suture material. The fastener catheter includes a catheter main body and a handle. The suture fastener has a generally cylindrical body formed of a shape memory material and a suture fastener inner lumen. The suture fastener has at least one engagement tab biased to extend at least partially into the suture fastener inner lumen to engage against and secure one or more lines of suture passing through the suture fastener.
