Abstract
A knot placement device allows a physician to apply a knot for securing two or more suture ends extending from an incision in a vessel or organ of a patient relative to each other in order to seal an opening in the vessel or organ. The knot placement device has a handle, an elongate shaft, and a push rod slidably inserted in the shaft. A knot is disposed in the distal end of the shaft. An actuator on the handle may be depressed to distally advance the push rod relative to the shaft, thereby distally advancing the knot. The knot may include a knot body having an inner cavity and a plug sized to fit securely within the inner cavity. In use, the plug may be inserted into the inner cavity of the knot body to fixedly hold two or more suture ends between the knot body and the plug.
