Abstract

A system and method for retaining a tissue specimen obtained via a collection tube is provided. Embodiments provide a system including a collection device removably and serially disposed between a collection tube and a suction tube so as to allow fluid communication therebetween via the collection device. The collection device includes a screen for retaining a tissue specimen drawn into the collection device by and towards the suction tube while allowing any fluid accompanying the tissue to be drawn through the collection device and into the suction tube. The system also includes one or more end caps for sealing the collection device such that the collection device may store and/or transport the retained tissue specimen in a preservation fluid. A system for identifying and organizing collection devices retaining tissue specimens from various anatomical regions is also provided.
