Abstract
An irrigation sleeve for a phacoemulsification needle is constructed with a non-uniform distribution of mass. When the sleeve is used with torsional phacoemulsification apparatus the sleeve adds to the eccentric motion of the needle, adding efficiency to the phacoemulsification process. In one embodiment, weights are implanted in the sleeve. In another embodiment the sleeve is molded with concentrations of sleeve material at selected locations in the sleeve.
