Abstract
An organ retention device and system, and use of the same for laparoscopic surgery is provided. The organ retention device includes a biologically compatible flexible barrier configured to restrain one or more organs. First and second anchor strings extend from first and second connection regions of the flexible barrier respectively and have a first and a second loop distal from the flexible barrier. At least one expansion element is configured to expand the flexible barrier generally perpendicularly to an axis between the first connection region and the second connection region when the first loop and the second loop are held apart in tension. A retraction device is also provided having a sharp distal end configured to enter an abdominal cavity by puncturing the abdominal wall, and a hook proximate to the sharp distal end configured to catch and retract one of the loops.
