A surgical knot pusher and method for use thereof to facilitate the tying of surgical sutures at remote sites within the body during endoscopic surgery and other minimally invasive surgical procedures, the knot pusher having a tubular, elongated housing having a passage defining a rod axis therethrough, a suture receiving tip forming a J-shaped hook defining a gap, a drive rod slidably disposed within the passage of the housing and extending substantially co-axial to the rod axis of the housing, wherein the drive rod is connected to the tip so that said tip is selectively operable between an open position, wherein axial movement of the drive rod relative to the housing causes a portion of the tip to extend beyond the distal end of the housing so that a length of suture may be inserted therein the gap of the hook of the tip, and a closed position, wherein axial movement of the drive rod relative to the housing causes the tip to be received within the passage of the housing proximate the distal end of the housing so that an eyelet having an aperture for releasably capturing the first length of the suture is formed, and a knot pushing surface formed from the exterior surface of the tip.

[ What is claimed is:] [1.]1. A medical instrument for positioning a suture knot formed from a first length of a suture and a second length of the suture at a surgical site remote from an opening to the site, the instrument comprising:a tubular, elongated housing having a proximal end, a distal end

[ What is claimed is:] [1.]1. A medical instrument for positioning a suture knot formed from a first length of a suture and a second length of the suture at a surgical site remote from an opening to the site, the instrument comprising:a tubular, elongated housing having a proximal end, a distal end and a passage defining a rod axis therethrough;gripping mechanism for releasably grasping the first length of suture proximate said distal end of said tubular housing, said gripping mechanism including a drive rod slidably disposed within the passage of said housing and extending substantially co-axial to said rod axis; and a suture receiving tip having a generally hook shape with a first end and a second end; and including pushing mechanism movable with respect to said housing for slidably pushing a knot formed from the two lengths of suture member, and wherein said suture receiving tip forms an acute angle relative to the rod axis so that the hook of said suturing tip lies in a plane angled relative to the rod axis of said housing.
