1. An apparatus for controlling the stimulation of neural tissue comprising:

  • an implantable electronics package;

    a neural stimulator within said implantable electronics package;

    an electrode array driven by the neural stimulator and suitable to stimulate neural tissue;

    an external processor wirelessly communicating with said implantable electronics package;

    a current pulse generator within said external processor providing instructions to said implantable electronics package for stimulating neural tissue;

    a meter device within said external processor for testing total power dissipation of said neural stimulator during stimulation of tissue; and

    a calculating device within said external processor for comparing said total power dissipation to a predetermined maximum power dissipation,wherein the current pulse generator is configured such that instructions from the current pulse generator to the implantable electronics package for stimulating a particular electrode in the electrode array are based on total power dissipation of the electrode array.
