Abstract

A medical knot tying instrument having a first member including proximal and distal ends, a gripping mechanism for releasably gripping a first length of suture proximate the distal end of the first member and a holding mechanism for releasably holding a second length of suture proximate the location where the gripping mechanism grips the first length of suture but separated therefrom a predetermined distance toward the first member's proximal end. Gripping one length of suture using the gripping mechanism and holding a second length of suture using the holding mechanism, the instrument is rotated in one angular direction so that the second length of suture forms a loop around the instrument whereupon the second length is grasped using a separate grasping instrument. The second length is then released from the holding mechanism and the two lengths of suture are moved in opposite directions so that the loop slides along and off the instrument while the first length passes through the loop of the second length, thereby forming a throw of a knot.
