Abstract
A suturing instrument and methods for placing stitches in soft tissues combines the functions of both independently grasping the tissue and passing sutures through the tissue to form a mattress stitch therein. The endoscopic suturing instrument comprises a clamping portion having a longitudinal axis, which is adapted for percutaneous entry into an operative site. The clamping portion further comprises a plurality of jaw members that are movable relative to one another between a closed position wherein the jaw members are disposed in close proximity to one another and an open position wherein the jaw members are spaced apart. A needle portion is disposed at an angle relative to the longitudinal axis, and is adapted for percutaneous entry into said operative site. The needle portion comprises a needle, and preferably a pair of needles, for passage through a portion of soft tissue disposed between the jaw members of the clamping portion.
