The Blackrock NeuroMed Cervello Bio-Potential Signal Acquisition Product Family contains the following configurations.
Ambulatory: Up to 64 channels with one Cervello hardware device (Amplifier) using the Cervello software. The device is intended to acquire and store physiological signals for EEG and/or PSG, and to transfer the data to separate polysomnographic analysis software. The devices are intended to be used by physicians, technicians and other medical professions that are trained in EEG and/or PSG. The Cervello Ambulatory system does not make any judgment of normality of the displayed signals or the results of an analysis. In no way are any of the functions represented as being in and of themselves diagnostic.
Basic: Up to 64 channels with one Cervello hardware device (Amplifier) and up to 128 channels by cascading 2 Cervello devices using the Cervello software. The device is intended to acquire and store physiological signals for EEG and/or PSG, and to transfer the data to separate polysomnographic analysis software. The devices are intended to be used by physicians, technicians and other medical professions that are trained in EEG and/or PSG. The Cervello Basic system does not make any judgment of normality of the displayed signals or the results of an analysis. In no way are any of the functions represented as being in and of themselves diagnostic.
Elite: Up to 128 with one Neuroport Bio-Potential Recording Systems and up to 256 by cascading two Neuroport systems using the Central and/or Cervello software. The system supports recording, processing and display of biopotential signals from user-supplied electrodes. Bio-potential signals include: Electrocorticography (ECGG), electroencephalography (EEG), electromyography (EMG), electrocardiography (ECG), electrooculography (EOG) and Evoked Potential (EP). Intended users include Physicians, clinicians or other medical professionals that are trained in bio-potential and/or EEG recording. The Cervello Elite system does not make any judgment of normality of the displayed signals or the results of an analysis. In no way are any of the functions represented as being in and of themselves diagnostic.
Multi-Channel, Multi-Modal Physiological Monitoring System
Cervello Ambulatory - This system uses the Cervello Amplifier in the ambulatory environment and provides up to 64 input channels for EEG and PSG studies. The Amplifier is battery powered during recording; the internal microcontroller stores the data in a RAM buffer and memory card where it can be downloaded later for review by a physician.
Cervello Basic - This is a PC-based clinician-oriented EEG and/or PSG monitoring system that provides between up to 128 channels for EEG recording using the Cervello Amplifier. Data is displayed on a monitor using the Cervello Basic software program and video capabilities are available.
Cervello Elite -- This is a PC-based clinician-oriented monitoring system that provides up to 256 channels for recording bio-potentials such as electroencephalography (EEG), electromyography (EMG), electroencephalography (ECG), electrooculography (EOG), electrocorticography (ECoG) and evoked potential (EP) using the NeuroPort Bio-Potential System Hardware and operates both the Cervello (Basic) and the Central Software. Video capabilities are available.
In all cases, and as with the predicate devices, the Cervello Basic, Ambulatory and Elite Systems are not monitoring systems. No physiologic alarms are provided. The acquisition and display of bio-potential signals is for the interpretation and use of the clinician. The devices do not make any judgment of normality or abnormality of the displayed signals and the software is not intended to do automatic analysis of the recorded signals
The Blackrock NeuroMed Cervello Bio-Potential Signal Acquisition System is a multi-channel, multi-modal physiological monitoring system with three configurations: Cervello Ambulatory, Cervello Basic, and Cervello Elite. The submission for this device is a consolidation/modification of existing devices, and its acceptance criteria and the study proving it meets these criteria are based on its substantial equivalence to predicate devices. The device is not intended to make any judgment of normality or abnormality of the displayed signals, nor is it a monitoring system with physiological alarms. Its purpose is to acquire, display, store, and archive bio-potential signals for interpretation and use by clinicians.
Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria for the Cervello Bio-Potential Signal Acquisition System are generally aligned with the performance characteristics of its predicate devices, as the submission aims to demonstrate "substantial equivalence."
