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

Wound closure device

A tissue segmentation device incorporated in an isolation bag for segmenting tissue during an operation such as in laparoscopic surgery. The device includes one or more loops of high strength wire which can be mechanically reduced in size to cut the tissue into smaller pieces. The wire loops can be heated electrically to aid in cutting through hard-to-cut parts of the tissue. The wire can be of a shape memory alloy which shrinks when heated to form a smaller diameter loop.
