The Neuro Omega system with the incorporated Navigation Tool software (the improved HaGuide software), including the Drive Headstage unit, is intended to assist neurosurgeons in the operating room during functional neurosurgery and to record from and stimulate brain motor and sensory neurons and to aid in the placement of depth electrodes.
The subject device, the Neuro Omega System with the incorporated Navigation Tool software is also intended:
- To monitor, record, and display the bioelectric signals produced by muscles, to stimulate peripheral nerves, and to monitor, record, and display the electrical activity produced by nerves to aid the clinician in the diagnosis and prognosis of neuromuscular disease (EMG).
- To measure, record, and display the electrical activity of the patient's brain obtained from two or more electrodes on the head (EEQG).
- To measure, display and record the electrical activity of the patient's brain obtained from ECOG strip and grid electrodes.
- To provide stimulation via electrode pairs or a hand-held bipolar probe for use in functional brain mapping procedures during treatment of patients with a seizure disorder.
The Neuro Omega with the incorporated installed Navigation tool software, is intended for intraoperative use by medical personnel. Within hospitals, laboratories, clinics, or nursing home settings or outside of a medical facility under the direct supervision of a medical professional. The device may also be placed in the intensive care unit or operating room for continuous recording.
The NeuroSmart System with the incorporated Navigation Tool software, is intended to be used in assisting neurosurgeons, in the operating room during functional neurosurgery, to record from and stimulate brain motor and sensory neurons and to aid in the placement of depth electrodes.
