1. A phacoemulsification cutting tip, comprising:
a rigid tubular portion and a flexible and expandable tip portion located distal to the rigid tubular portion;
the flexible and expandable tip portion defining a distal opening at a distal end thereof, the distal opening being flexibly expandable along with the expandable tip portion; and
wherein the flexible and expandable tip portion further comprises a woven structure whereby aspiration of crystalline lens fragments is facilitated by expansion of the distal opening to accommodate aspiration of the crystalline lens fragments that are larger than distal opening when the distal opening is unexpanded that may at least partially block the distal opening when unexpanded.
