Abstract
A suture implant for approximating tissue without tying knots includes a suture having a first end with a fixed knot, a second end, and a slip knot located between the first and second ends, which defines a large suture loop having a length. The slip knot defines a dynamic end of the large suture loop that is located opposite a closed end of the large suture loop. A tissue anchor is coupled with the first end of the suture. Pulling the second end of the large suture loop away from the slip knot slides the slip knot and the tissue anchor toward the closed end of the large suture loop and reduces the length of the large suture loop. The suture implant includes a needle having a leading end and a trailing end and a small suture loop secured to the trailing end of the needle that is coupled with the closed end of the large suture loop.
