Abstract

An insertion tool having an insertion guide tube that maintains a perimodiolar or other pre-curved electrode assembly in a substantially straight configuration while preventing the electrode assembly from twisting in response to stresses induced by the bias force which urges the assembly to return to its pre-curved configuration. This generally ensures that when the electrode assembly is deployed from the distal end of the insertion guide tube, the electrode assembly and insertion guide tube have a known relative orientation.
