Ojemann Cortical Stimulator

Designed in collaboration with Dr. George Ojemann at the University of Washington, the Ojemann Cortical Stimulator is the industry standard for cortical stimulation mapping procedures. This portable,constant current unit has simple, uncomplicated controls and current settings suitable for use in the awake or anesthetized patient.The Ojemann Cortical Stimulator is a compact, battery-powered unit and supplies up to 20 milliamps current (peak to peak). 

1.    Portable, Constant Current unit has simple, uncomplicated controls and current settings suitable for use in the awake or anesthetized patient.
2.    Stimulus Output upto 20 milliamps current (peak to peak), Selectable range: 0-1 mA peak and 0-10 mA peak to peak. Includes two knobs that allow continuous adjustments within these ranges.
3.    Biphasic rectangular waveforms with rate selectable at 5, 10, 20, 50, 60, 75 and 100 pulses/sec and duration selectable at 0.1, 0.2, 0.5, 1 and 2 millisecond. The Polarity (positive or negative leading pulse) is also selectable.
