Abstract
A knot-tying assist device allows a physician to remotely tie and cinch a knot in two ends of a suture extending from an incision in a vessel or organ of a patient in order to seal an opening in the vessel or organ. The knot-tying assist device includes a first receiving portion and a second receiving portion spaced apart along the device for receiving and holding the two ends of the suture. The receiving portions may hold the suture ends loosely, or alternatively may hold the suture ends under tension to facilitate tying the knot. The knot-tying device further includes an engagement portion to stabilize the knot-tying assist device relative to the treatment location. The engagement portion may assist in maintaining tension on the two suture ends so that the suture can hold the incision closed prior to the knot being tied and cinched.
