Why are cochlear implants limited to human range of sound?

It seems like it might be able to be extended (i.e. could hear dog whistles, etc.).  Is it a limitation with the brain, the technology?  Or is it simply to give the recipient "normal" hearing patterns?

Sure, we have the technology to increase the frequency range on cochlear implants, but the reason they aren't is because human communication is done well within the range of normal hearing. Focusing on that range is the most efficient way to use the limited number of electrodes (22) that replace the 16,000 or so hairs normally used for hearing. Taking just one electrode outside the normal range of hearing would reduce the overall efficacy of the device with no improvement of the main purpose of the device, communication.
