Neurovision Medical Products• Focus – Proactive nerve location
technology
• Nerveäna – The 4th Generation Nerve Locator
• 25 year track record of success
Delivers stimulations and analyzes the responses
• Delivers milliamp pulses via Stimulating Hemostat
• Analyzes responses of nerve via (surface) electrode- Gives the surgeon feedback in audio alarm
and audio electromyograph (EMG)
- EMG waveforms can be displayed on a PC
• The Result: An intuitive surgical nerve location tool
