Abstract
The suturing instrument includes an elongate member having an articulating distal portion biased offset from the elongate member, and a sheath slideably disposed about the elongate member. The user positions the sheath in contact with the articulating distal portion to actuate the distal portion relative to the elongate member. The articulating distal portion is pivotally coupled to the elongate member for improved maneuverability within the body of a patient during surgical procedures.

1-23. (canceled)
A suturing instrument comprising:
- an elongate member having a longitudinal axis and comprising a distal end;
- a distal portion coupled to the elongate member at the distal end and defining a needle exit port, the distal portion configured to move from a first position, in which the distal portion aligns with the longitudinal axis, to a second position, in which the distal portion moves away from the longitudinal axis;
- and
- an actuation mechanism comprising a slideable push rod configured to engage with a recess of the distal portion and move the distal portion from the first position to the second position.

A suturing instrument comprising:
- an elongate member including a proximal end, a distal end and a longitudinal axis extending therebetween;
- a distal portion pivotably coupled to the distal end of the elongate member via an articulation joint and defining a needle exit port, the distal portion biased in a configuration extending along the longitudinal axis;
- and
- an actuation mechanism for offsetting the distal portion from the longitudinal axis, the actuation mechanism comprising a push rod at least partially disposed in the elongate member, the push rod coupled to a recessed area in the distal portion, the recessed area configured for engaging a distal end of the push rod, whereby when the push rod is slid in a distal direction the distal end of the push rod engages the recessed area to offset the distal portion relative to the longitudinal axis, and whereby sliding the push rod in a proximal direction allows the distal portion to return to its biased position along the longitudinal axis.
