We have developed a means to accomplish proportional steering control of a flexible needle by controlling the orientation of the needle and spinning it with a variable duty cycle. This approach makes it possible to reach deep lesions with high accuracy using an extremely narrow probe. Both of these characteristics offer important advantages for neurosurgery. To date we have demonstrated the technique in vitro in artificial media (as in the photograph below).
