1. A medical device configured to close a soft tissue defect, the device comprising:
an elongate body having a strap at a proximal end, a leader at a distal end, and a transition section joining the strap to the leader;
wherein the leader has a lower bending stiffness than the strap;
wherein the stiffness of the transition section gradually decreases from the strap to the leader;
wherein the leader comprises at least one loop formed from a distal portion of the leader and
a lock-head disposed at the proximal end of the strap, the lock-head having an aperture for receiving the distal end of the strap, the aperture configured for permitting at least one controlled translation of the strap in one direction through the lock-head and restricting motion in the opposite direction, wherein the controlled translation comprises a tightening of the strap.
