Abstract
In one aspect of the invention, a multi-purpose phacoemulsification needle comprises a needle body disposed about a centerline and has a lumen disposed therein. The lumen has a first cross-sectional area that is normal to the centerline. The needle further comprises a distal tip comprising an arcuate surface and a face with a port therein. The port has a second cross-sectional area in a plane generally parallel to the face and is in fluid communication with an internal cavity that has a third cross-sectional area normal to the centerline, the internal cavity being in fluid communication with the lumen. The needle is configured such that the third cross-sectional area is greater than either the first cross-sectional area or the second cross-sectional area. In another aspect of the invention, the needle comprises a plurality of fins projecting inwardly from the lumen.
