Abstract

A cassette for collecting a tissue sample. The cassette includes a housing configured to be removably coupled with a manifold receiver of a medical fluid collection system. The housing defines a first void space, a second void space, and an outlet opening. A catch tray is removably positionable within the first void space and includes a screen defining porous features for collecting the tissue sample. A filter element separate from the catch tray is disposed within the second void space. The housing may include a cap portion defining the first void space, and a shell portion coupled to the cap portion and defining the second void space. The cassette may be simultaneously operable in a tissue collection mode in which fluid is suctioned across the catch tray to collect the tissue sample, and a bypass mode in which the fluid is not suctioned across the catch tray.
