Abstract
A device and method for retrieving specimens from a body cavity during minimally invasive surgery uses a specimen pouch that is deployable from an introducer inserted into the body cavity through a predefined passage such as a cannula. The specimen pouch includes a resilient band that causes the specimen pouch to open automatically and remain open after removal from the introducer. Once removed from the introducer, the specimen pouch is free-standing with no attachment to the introducer or to an externally operated closure mechanism. Closure and removal are accomplished using a conventional forceps or other instrument to grasp a portion of the band and withdraw the band and the opening of the pouch into the introducer. The pouch is configured so that withdrawal of the band into the introducer causes the material around the opening of the pouch to gather and seal the opening.
