An instrument is provided having a shaft extending to a distal end having a cavity, and a passageway extending to the cavity through which a first suture end of a suture loop extends from a tissue site to facilitate a user looping a second suture end around the first suture end between the tip and the site to form a knot. Advancing of the distal tip while drawing the first suture end through the passageway pushes the knot to the site. The distal tip of another embodiment adds another passageway through which the second suture end is passed to assist in forming and pushing a knot at to the tissue site. The distal end has two openings through which two suture ends are passed from the placed knot, and a blade in the distal end is positionable to cut the suture ends near the knot.
