1. A wound closure system comprising:
a suture line adapted to pass into the body tissue at an entry point and exit at an exit point adjacent an open wound, the suture line including a plurality of barbs extending outwardly with respect to a surface of the suture line; and
a housing configured to house a biasing member that is adapted to apply tension on the suture line thereby taking up slack of the suture line while stretching the body tissue toward the open wound.
