First Claim
1. A dynamic surge suppressor for use in a phacoemulsification surgical procedure for the removal of lens tissue from an eye of a patient, which comprises:
- a suppressor housing having an inner passage;
a mesh filter located within a portion of the inner passage of the suppressor housing;
a tube, having an unobstructed inner passage with a prescribed diameter, located in a portion of the inner passage of the suppressor housing not occupied by the mesh filter;
the tube unattached to any portion of the suppressor housing, and movable freely independently, and axially, within the inner passage of the suppressor housing; and
a separate inner passage, independent of the unobstructed inner passage of the tube, formed by a space between an outer surface of the tube and an adjacent portion of an inner wall of the inner passage of the suppressor housing.

Abstract
A surgical apparatus 10, used in a phaco procedure, includes a filter assembly 44/44a for near, or complete, elimination of air bubbles in an aspiration line of an aspiration system 38. The apparatus 10 includes a suppressor 110, which, during an aspiration mode of operation, maintains a fluid flow rate at 50 cc/min, and, upon an occlusion breaking free, dynamically decreases the fluid flow rate from a high surge rate to the rate at 50 cc/min. The apparatus 10 includes facility for operating in a reflux mode to direct unrestricted fluid flow through the aspiration line of the aspiration system 38.
