Abstract
A reusable cartridge assembly for a phaco machine includes a first plate with a plurality of flow channels therein and a sealing gasket with a sheet for sealing against the first plate to prevent fluid from leaving the flow channels. In addition, a tube is provided, fixed to the sealing gasket and protruding therefrom, for enabling engagement between the tube and a pump head for circulation of fluid through flow channels. A second plate is provided for applying a sealing pressure between the sheet and the first plate. In addition, the sealing gasket may include a sensing element for determining pressure within the flow channels.
