a bottom jaw member extending between a proximal end and a distal end and comprising a first bottom anchor target slot formed in a perimeter edge of the bottom jaw member and a second bottom anchor target slot formed in the perimeter edge of the bottom jaw member; and
a joint member connected to the proximal ends of the top jaw member and the bottom jaw member;
wherein the top and bottom jaw members, in an open position, define an area for receiving a portion of tissue, and the joint member articulates the jaw members from the open position to a tissue engaging position wherein the top and bottom jaw members grasp the portion of tissue;
wherein, when the jaw members are in the tissue engaging position, the first top anchor slot and first bottom anchor slot are adapted to receive a first anchor extending into the first top anchor slot, through the portion of tissue, and out of the first bottom anchor slot; and
wherein, when the jaw members are in the tissue engaging position, the second top anchor slot and second bottom anchor slot are adapted to receive a second anchor extending into the second top anchor slot, through the portion of tissue, and out of the second bottom anchor slot; and
