US Patent 7326181 Nervous tissue stimulation device and method

A method using a precisely controlled, computer programmable stimulus for neuroselective tissue stimulation that does not leave a sufficient voltage or electrical artifact on the tissue being stimulated that would interfere or prevent a monitoring system from recording the physiological response is utilized to evaluate the physiological conduction of the tissue being studied. A computer controls both the waveform, duration and intensity of the stimulus. An output trigger to the nerve response recording component controls the timing of its operation. A neuroselective nervous tissue response latency and amplitude may be determined. The computer controlled stimulus may also be administered for therapeutic purposes.
