Video shows a steerable model of electrode arrays for cochlear implant surgery. The implant is built from an elastomeric body with an embedded Kevlar strand. The strand location controls the bending shape in 2-D and 3-D. The video shows one model that moves in plane [1, 2]. In [1] we reported the optimal planning of the insertion path. In [2] we reported the optimal strand location to achieve optimal insertion in 3-D cavities. References:
