ABSTRACT:
Suture-based fasteners and fastening methods for soft tissue reconstruction are described that can include a needle tip swaged onto two sutures and loaded onto the end of a curved needle shaft. The needle shaft and tip can be driven through the tissues to be sutured and back out to where the needle tip can make a permanent connection with a locking bead. The needle shaft can be retracted, leaving two sutures extending from the side of the bead. One suture can be of nonabsorbable material and can be brought through the end of the locking bead opposite the tip and pulled to tighten the suture loop. The other suture can be of an absorbable material and can be used to rotate the locking bead under one of the layers of tissue being sutured after the suture loop is tightened. Following rotation, the second suture can be trimmed.
