A tissue retrieval device includes an introducer tube and a tissue retrieval bag. The introducer tube is sized to be inserted into a patient through a trocar. The tissue retrieval bag may be selectively exposed at the distal end of the introducer tube within the patient. The tissue retrieval bag may receive a tissue specimen and be withdrawn from the patient. The tissue retrieval bag may include an inflatable portion. When inflated, the inflatable portion may extend the tissue retrieval bag from a contracted configuration to an expanded configuration. The inflatable portion may substantially seal a tissue specimen within the tissue retrieval bag. The tissue retrieval bag may me formed of an environmentally sensitive material such that the size of the tissue retrieval bag expands when the tissue retrieval bag is exposed within the patient.
