  • Patent number: 11944278
    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.

  • Publication number: 20230330317
    Abstract: A manifold for a medical/surgical waste collection system. An outlet opening and a fitting are in fluid communication with a manifold volume within a housing. The fitting receives a suction line. A filter element with porous features is disposed within the housing such that a fluid communication path is established across the filter element. The porous features trap material entrained within the fluid. A material collection volume is at least partially distal to and below a bottom of the filter element. As the fluid and the material is drawn through the fluid communication path, the material collects within the material collection volume. A flow diverter may be positioned within the housing for directing the material towards the material collection volume. The material collection volume may be at least partially defined by a tissue trap removably coupled to the housing.
