Abstract
An aspiration tube has a relatively high fluidic resistance. The tube is coupled to a medical device and a pump of an aspiration system. The tube can be designed to create a pressure drop that at least equals the maximum vacuum pressure of the pump. The fluidic resistance can be accomplished with a tube having an inner diameter less than 0.05 inches. The aspiration tube and an irrigation tube may be coupled to an anterior chamber of a cornea during a phaco procedure. The aspiration tube is sized so that even if a maximum pressure occurs, the resultant aspiration flowrate will be such that the cornea will not be damaged when an occlusion is cleared from the tube. An in-line filter may also be attached to the aspiration tube to filter out particles in the system.
