Abstract: A purse string suture instrument includes an end effector with first and second jaws disposed at a distal portion of an elongate tubular shaft. The first and second jaws are pivotably coupled to each other and to the elongate tubular shaft. The first and second jaws are spaced apart and define a gap therebetween. First and second pluralities of teeth extend perpendicularly from the first and second jaws respectively, and the first plurality of teeth is longitudinally offset from the second plurality of teeth. The first and second jaws are transitionable between open and approximated configurations. The approximated configuration is adapted to clamp tissue in the gap between the first and second jaws, thereby displacing sections of tissue outwardly between the first and second pluralities of teeth.
