Abstract
The implantable electrode system of the preferred embodiments includes a conductor, an interconnect coupled to the conductor, an insulator that insulates the interconnect, and an anchor that is connected to both the conductor and the insulating element. The anchor is mechanically interlocked with at least one of the conductor and the insulator.
