Abstract
A wound closure device which maintains pneumoperitoneum while allowing a surgeon to capture an mount of tissue which is substantially wider than the diameter of a trocar cannula through which the device is inserted. The wound closure device includes, an elongated guide member, a hook shaped needle and a retracting mechanism for moving the needle from an open position to a closed position. In the closed position, the tip of the needle is positioned within the guide member so that the needle can be easily inserted into a body. In the open position, the needle tip is positioned outside of the guide member at a distance from the guide member which is greater than the diameter of the guide member. The device is inserted into a body through a wound in the closed position, the needle is deployed within the body by a handle and then the needle is drawn through the tissue to suture the wound
