The first cassette forms an aspiration passageway and a collection area, and the second cassette includes a body and an infusion tube. Preferably, the base member and the second cassette form a vacuum passageway in fluid communication with the aspiration passageway. In operation, an aspiration tube is connected to an inlet of the aspiration passageway, and an outlet of the vacuum passageway is connected to a source of vacuum pressure. An infusion fluid is conducted through the infusion tube and to a surgical site, and that site is aspirated via the aspiration tube. The aspirated materials are drawn into the aspiration passageway and thence into the collection area.
