Abstract
A superior cassette is provided for maintaining sterility of internal tubing sections that are to be repeatedly clamped under the control of external actuators when the cassette is inserted in an associated system, such as an irrigation/aspiration system for ophthalmic surgery applications. An inserted leading edge presents faces of interior sliders to actuators which reciprocate the slider to engage and clamp tubing sections positioned near the opposite, intercoupling edge of the cassette. All contact is made within the sterile interior of the cassette so that sterile flows cannot be contaminated even if leakage or puncture occurs under handling or repeated operation.
