Flexible transport auger

Abstract

A flexible auger design for low-torque transmitting drive shafts, which allows effective tissue material transport through curved, flexible tubes and channels. A hollow auger has a hollow center, so that the helical member hugs the inner wall of the tube and material is transported along the center axis and the inner wall of the tube. The hollow flexible auger allows for transportation of material from an operative location in the patient (material removal) as well as to operative location in the patient (material delivery).
