Abstract: Systems and methods for closing a tissue defect. The systems may include a subcutaneous guide that is placed transcutaneously between two skin access sites and a self-locking strap that may be advanced into the body through a first access site via a first needle and then passed to a second needle. The strap may be withdrawn with the second needle through a second access site to the outside of the body. The strap may be withdrawn from the first needle, leaving the strap placed through both access sites and across the defect. As the subcutaneous guide is withdrawn from the body it pulls the captured strap such that both ends of the strap protrude from the first access site, allowing the strap to be tightened around the defect.
