Abstract
A phacoemulsification cutting tip, including a rigid tubular portion and a flexible and expandable tip portion located distal to the rigid tubular portion. The flexible and expandable tip portion presents an axial length and an unexpanded radius and is formed such that the axial length shortens while the unexpanded radius increases when differential pressure due to an occlusion of an opening of the flexible tip portion exists.
