ABSTRACT:
A way of reducing channel interaction is provided in a multichannel neural implant that has the ability to stimulate multiple tissue or nerve sites simultaneously. Channel interaction is minimized through measuring or estimating what the channel interaction is or will likely be, and then using that measured or estimated channel interaction to adjust the intensity of the applied stimuli so that, with the channel interaction, the actual stimuli applied to the tissue or nerves is of a desired intensity level. In one embodiment, the measured or estimated channel interaction is collected or compiled and saved as a channel interaction matrix. The channel interaction matrix is created during a fitting procedure by stimulating one channel at a time while measuring the effects of the stimulation on the neighboring channels. The superposition principal is used, as needed, to determine all the terms of the channel interaction matrix. The channel interaction matrix, once obtained, provides all of the information needed to eliminate or minimize channel interaction.
