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.

How It Works

The NIM Nerve Monitoring System is an electromyographic (EMG) monitor for intraoperative use during various surgeries, including ENT and general surgical procedures in which a nerve may be at risk due to unintentional manipulation. NIM nerve monitoring electrodes are placed in the appropriate muscle locations in the patient for the procedure being performed. (Color-coded placement guides are included in the NIM software.)

These electrodes are connected to the NIM Nerve Monitoring System, which continuously monitors EMG activity from muscles innervated by the affected nerve. When a particular nerve has been activated or stimulated, the NIM System warns the surgeon and operating room staff, providing both visual alerts on the color touchscreen monitor and audio feedback to help minimize trauma to the nerve.

Surgeons can use monopolar and bipolar stimulating probes and dissection instruments with the NIM Nerve Monitoring System to assist in early nerve identification and confirmation. These tools may be used to locate, identify, and map the particular nerve and branches, as well as verify nerve function and integrity.

By combining sophisticated hardware electronics and intuitive software, the NIM Nerve Monitoring Systems help surgeons perform critical procedures while preserving nerve function and improving patient safety.
