ABSTRACT:
A knot pusher includes a shaft with a distal nose configured for pushing a suture knot. The nose has a surface with a an open suture receiving recess. A securing member is arranged for movement between a closed position and an open position. In its closed position, the securing member at least partially covers the suture receiving recess to prevent removal of a suture therefrom. In its open position, the securing member permits removal of the suture from the suture receiving recess. An actuator moves the securing member between its open and closed positions. The securing member is arranged to slide or pivot relative to the shaft. The securing member is associated with the shaft such that an outer diameter of a distal end of the shaft is not substantially increased with the securing member in its closed position. A method of tying a suture is also described.
