Abstract
A medical device for approximating and securing tissue without requiring knots includes a lock-head, a strap section, distal protuberance, and a leader section. The device also includes a transition section between the leader and the strap section and a stiffening section proximal to the protuberance. The leader section is used to draw the strap section into the body through small apertures in tissue and the transition section provides a gradual transition in stiffness and size between the leader and the strap section.
Claims20
A method for tensioning a soft tissue defect, comprising:
- providing a first medical device, the first medical device comprising:
- an elongate body comprising:
- a strap at a proximal end of the elongate body,
- a leader at a distal end of the elongate body, the leader comprising a loop formed from a distal portion of the leader, wherein the leader has a lower bending stiffness than the strap, and
- a transition section joining the strap to the leader, wherein the stiffness of the transition section gradually decreases from the strap to the leader;
- and
- a lock-head disposed at the proximal end of the strap, the lock-head comprising an aperture for receiving the distal end of the strap;
- placing the distal end of the first medical device through a first hole on a first side of the soft tissue defect and into a body cavity;
- pulling the leader of the first medical device through a second hole in the soft tissue on a second side of the soft tissue defect opposite the first side;
- pulling the leader of the first medical device through the first hole;
- passing the leader through the lock-head;
- and
- tightening the first medical device by translating the strap a distance through the lock-head in a forward direction, wherein the lock-head prevents translational movement of the strap in a direction opposite the forward direction.
