Abstract
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.
