Precautions
This Operator's Manual is to be used in conjunction with the Ojemann Cortical
Stimulator Probe (OCS2PND) Instructions for Use (IFU).
Warning
The displayed output of this device is
measured in peak milliamperes. Since the
output signal is biphasic, the actual peak to
peak current is two times the displayed
peak current. Therefore, this device is
capable of a maximum output current of 20
mA peak to peak. Simultaneous
connection of a patient to this device and
High Frequency surgical equipment may
result in burns at the side of the stimulator
electrodes and possible damage to this
device. Operation in close proximity to
short wave or microwave therapy
equipment may produce instability in the
stimulator output.
Intended use
The Ojemann Cortical Stimulator (OCS2) is intended for intraoperative cortical
stimulation mapping procedures to aid in the cortical resections in the vicinity of the
essential cortex.
Description
The Ojemann Cortical Stimulator (OCS2) is a portable, battery-operated bipolar
stimulator. It supplies a constant current in two ranges: 0-1 milliamperes and 0-10
milliamperes, baseline to peak, into a 0 to 2 KΩ load. An LCD displays the delivered
current baseline to peak. The Pulse Duration selections are 0.1, 0.2, 0.5, 1 and 2
milliseconds with Pulse Rate selections of 5, 10, 20, 50, 60, 75, and 100 Hertz.
