A method for better isolating and removing a large mass of excised tissue from a female patients abdominal cavity during a laparoscopic surgery includes the steps of: (1) vaginally inserting a collection bag that includes: (a) a flexible and resilient ring adapted to enable: the ring to be distorted for vaginal insertion, a specified ring open area sized to allow the mass of tissue to pass through it, and the ring to be removed from the patients abdominal cavity through a laparoscopic-surgery-appropriately-sized incision, (b) a sleeve having a flexible wall and open end that is affixed to the ring and a defined interior volume sized so as to allow the mass of tissue to reside in the sleeve, and (2) utilizing the collection bag to contain the mass of tissue.
