A phacoemulsification device that features an applicator tip as in a cutting tip for insertion into an eye and into contact with a cataract. The device includes a shaft having a phacoemulsification movement generator connector end at a proximal location and an applicator tip supporting end at a distal end, and the shaft further includes a shaft section that extends in a region positioned between the proximal and distal ends of the shaft, and the shaft section having a convoluted exposed surface which includes longitudinally extending projections and longitudinally extending valleys arranged in sequence about the circumference of the shaft section. The projections are formed in an exemplary embodiment as to be free of any edges as in, for example, an embodiment that includes projections and valleys that have smooth sloped curving walls in cross section and which smooth sloped curving walls include a plurality of mirror image S-shaped regions extending from a maximum radial extension region of a first projection, down to a maximum depth valley region of a first valley and up to a maximum radial projection of a second projection, with the valley region being positioned between respective first and second projections.
