Abstract:
1. A tissue ligation system, comprising: a deployment device having a knotting element coupled thereto, the knotting element having an outer member and an inner member that is slidably received in the outer member; a strand of suture passing thought a lumen in the inner member, the suture forming a loop extending distally from the inner member and having trailing ends extending proximally from the inner member; a handle coupled to a proximal end of the deployment device and having an actuation mechanism disposed thereon; and a sheath slidably disposed over the deployment device, the knotting element, and the loop, the sheath being operably coupled to the actuation mechanism such that the movement of the actuation mechanism is effective to slide the sheath over the deployment device, the knotting element, and the loop; wherein when the outer member is positioned over the inner member, the strand of suture is engaged therebetween with trailing ends of the suture extending distally from the knotting element in the same direction as the loop.
