Each tooth of the longitudinal rows of teeth of the first and second jaws includes a needle channel (29, 30) extending therethrough. The elongated rails and the longitudinal rows of teeth of the first and second jaws are disposed in opposed relation relative to each other. The needle assembly includes a first needle (46), a second needle (46), and a suture (47) coupled to the first and second needles. The first needle is slidable through the needle channels of the first jaw and the second needle is slidable through the needle channels of the second jaw.
