Abstract
An infusion control system having a flexible, collapsible infusion container. The container can be compressed between rollers or plate so at to pressurize the container. Such a system allows for rapid pressure response rates without the need of venting devices or air filtering. The may also include an irrigation flow sensor. The sensor may be placed in the control console or in the infusion handpiece. Irrigation flow measurements provided by the sensor allows the control system to vary irrigation pressure and/or flow, aspiration pressure and/or flow and power supplied to the handpiece more accurately than sensors that monitor aspiration flow.
