The invention encompasses devices and methods used to provide wound closure based on rings positioned within the tissue layers of the wound opening (with the rings regionally separate the wound depth tissue layers into 2 compartments), followed by suture transport through the rings and full-thickness tissue layers of both compartments. Upon suture transport via synchronous or asynchronous manner and device removal, wound closure is achieved by tying the 2 ends of the suture without incorporating tissue above the level of the rings such as skin. When the device is applied to abdominal or chest wall wound opening, all tissue layers except the skin are incorporated in the suture closure of the wound. The closure process can be performed in a simple, reliable, and expeditious manner.
