Abstract
A tissue specimen retrieval bag assembly includes a tissue specimen bag having an open proximal end and a closed distal end, the proximal end including a cuff defined therein and extending therearound. A flexible bag brim is disposed within the cuff and is transitionable between a first, collapsed configuration and a second, expanded configuration. The flexible bag brim includes a cross section configured to facilitate both furling the tissue specimen bag onto itself around the bag brim when the bag brim is disposed in the second, expanded configuration and securing the tissue specimen bag in a desired furled configuration. The flexible bag brim includes a plurality of scallops defined along an inner peripheral surface thereof configured to facilitate furling the tissue specimen bag onto itself.
