The Neurovision Nerve Locator/Monitor is an electronic device consisting of a surgical nerve stimulator and an evoked EMG monitor with integrated detecting and warning capability. This device is intended for use in surgical procedures where motor nerves are at risk to assist the surgeon in locating these nerves. This device is intended for use only by qualified, trained medical practitioners who perform operative surgery and who fully understand that this device is only an adjuvant to proper surgical technique and good surgical judgment.

The EMGView software is an accessory to the Neurovision Nerve Locator/Monitor. When the dedicated USB output of the EMG unit is connected to a personal computer, the PC installed software provides status monitoring data, troubleshooting data, real-time EMG waveforms, and digital backup of all data obtained during clinical use of the device. The real-time display of EMG waveforms is intended to assist the surgeon with nerve integrity monitoring.

Indications for use as stated in the FDA 510(k) statement.
