Medtronic NIM-Response 3.0 Features
The Medtronic NIM-Response 3.0 system is used in a wide variety of applications including Intracranial, Extracranial, Intratemporal, Extratemporal, Neck Dissection, Thoracic Surgeries, lower and Upper Extremities, and Spinal procedures. The NIM system uses EMG activity from the patient’s muscles to monitor the nerves that could be at risk. By monitoring the patient’s nerves during procedures it can reduce the risk of damage during procedures.
The NIM System includes a color touch screen to make it easier to use. There are three individual modes and a customizable setting. The NIM-Response 3.0 can monitor up to four channels, or four individual nerve-muscle combinations at one time. The system USB port making it easy to transfer documents for storage in a medical facility.
