A wound closure apparatus can be a self-contained device for delivery and deployment of a tissue engineered wound plug that can secure fascial closure of laparoscopic port-site wounds. The wound plug can include a subfascial rivet head, a suprafascial rivet head, and a compressible column. Once in the wound, the wound plug may be deployed with the subfascial rivet head below the fascia of the wound and the suprafascial rivet head above the fascia of the wound. As this occurs, the column of the wound plug can be stationed within the opening of the wound. Once the wound plug is secured above, below, and within the fascial defect, the rivet heads may be interlocked within an inner channel of the column and remaining elements of the apparatus may be removed and discarded.
