SYSTEM AND METHOD FOR TISSUE RETRIEVAL

Embodiments of the invention provide a retrieval device and method for retrieving tissue from a body cavity. The retrieval device includes a pouch having an aperture and a pouch wall defining an interior space. An inflatable rim is coupled to the pouch and facilitates retrieval of the tissue into the interior space of the pouch. The retrieval device further includes a closure device coupled to the pouch wall for enclosing the tissue within the interior space of the pouch. A portion of the pouch wall includes a self-sealing characteristic that allows an instrument to pierce the pouch wall and the pouch wall is resealable after withdrawal of the instrument. The pouch can move from a retracted position to a expanded position upon inflation of the inflatable rim, which can then be separated by application of a separation force at an area of material weakness in the pouch wall.
