AN INFLATABLE PNEUMOPERITONEUM DEVICE

An inflatable artificial pneumoperitoneum bag 800 for receiving tissue 840 during laparoscopic surgery has a tissue-receiving opening at a proximal end thereof defined by a cuff 811 at the proximal opening. The cuff 811 has a closed configuration for delivery and retrieval of the bag 800 and an open configuration to receive tissue. The cuff 811 is biased into the open configuration. The bag 800 has a main body which extends from the cuff and the main body of the bag is more flexible than the cuff 811. A biasing element 815 bias's the cuff 811 into the open configuration. A tether 809 is used to close the bag for retrieval. The bag 800 creates an artificial pneumoperitoneum which isolates tissue within the bag.
