Nimbus i-Care - IntraOperative Neurophysiological Monitoring device

Dedicated to surgeons for a daily use

IntraOperative nerve monitoring systems enable surgeons to identify, confirm, and monitor motor nerve function to help reduce the risk of nerve damage during various procedures, including general and ENT surgeries.

The NIMBUS i-Care is an IntraOperative NeuroMonitoring (IONM) and NeuroStimulator device. It is dedicated to surgeons for daily use in the operating rooms, as well as for neurosurgery, otology and spine surgery.

Two simultaneous modes are available: « Stimulation » and « Monitoring » with pre-determinated and personalized settings which ensure a quick start and secure use of the device by the medical staff.

When nerve monitoring is necessary, Innopsys probes are placed in the appropriate muscle locations in the patient for the procedure being performed.

These electrodes are connected to the Nimbus i-Care, which continuously monitors EMG activity from muscles innervated by the affected nerve. When a particular nerve has been activated or stimulated, the Nimbus i-Care 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, bipolar or tripolar stimulating probes and dissection instruments 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, our Nimbus i-Care help surgeons perform critical procedures while preserving nerve function and improving patient safety.
