Right Median Nerve Stimulator (RNS-913) presents a new modality in treating “Comatose” patients. New studies have shown that there is considerable improvement in patient conditions after using the stimulator.The right median nerve stimulator provides pulses that are “Asymmetric Biphasic” in nature and controlled by a fast microcontroller. The stimulation duration is just 320 microseconds with a constant current control. The device is completely safe for use on humans.
