CNS Envision is intended for use by qualified personnel in the review, and analysis of patient data collected using external physiological monitors. These data are: raw and quantitative EEG, recorded video data, generic vital signs, electrocardiography, electromyography, intracranial pressures, transcranial Doppler measurements, and Glasgow Coma Score. CNS Envision includes the calculation and display of a set of quantitative measures intended to monitor and analyze the EEG waveforms. These include, for example, frequency bands, asymmetry, and burst suppression. These quantitative EEG measures should always be interpreted in conjunction with review of the original EEG waveforms. The aEEG functionality included in CNS Envision is intended to monitor the state of the brain. CNS Envision is intended for use by a physician or other qualified medical personnel who will exercise professional judgement in using the information. It is intended for use on patients of all ages. This device does not provide any diagnostic conclusion about the patient's condition to the user.

CNS Envision is a Microsoft Windows-based software application that facilitates the review, annotation and analysis of patient data and physiological measurements. Some of these data, such as ECG, are displayed in raw format whereas other types, such as EEG, are analyzed and quantified by the software. The specific type of input data that are reviewable by CNS Envision software are: Raw electroencephalography (EEG) Quantitative EEG trends; density spectral arrays (DSA) spectral edge frequency (SEF), alpha-delta ratio (ADR), and amplitude EEG (aEEG) Video Generic vital signs which are heart rate (HR), respiration rate (RR), pulse oximetry (SpO2), blood pressure, arterial blood pressure (ABP), mean arterial pressure (MAP), and body temperature Electrocardiography (ECG) Electromyography (EMG) Intracranial pressure (ICP) Transcranial Doppler (TCD) measurements (e.g. spectral envelope, peak velocity, and pulsatility index; TCD measurement is collected by the predicate K080217 device's interface module which interfaces with the Spencer TCD device cleared in K002533, which was a predicate to the predicate K080217 Glasgow Coma Score (GCS); this parameter is manually entered on the CNS Monitor (K080217) with 3 total GCS scores by the user; the CNS software automatically sums the 3 scores and stores the data to provide a trend graph CNS Envision also has several features to enable ease-of-use. For example, users may select customized layouts that provide data displays that can be tailored to their monitoring needs according to data sources. The subject device also offers customizable EEG montages that present raw EEG data to medical personnel for interpretation. Unlike the predicate device, Component Neuromonitoring System™, the subject device does not perform direct data acquisition. Instead, it offers the ability to review data remotely or adjust the review speed.

The Component Neuromonitoring System™ is intended to monitor the state of the brain by recording and displaying EEG signals, and can also receive and display a variety of vital signs and other measurements from third-party monitoring devices (such as ICP, ECG, SpO2, and others). It also has the optional capability to record and display patient video. The Component Neuromonitoring System is intended for use by a physician or other qualified medical personnel. It is intended for use on patients of all ages within a hospital or medical environment, including the operating room, intensive care unit, emergency room, and clinical research settings.

The Component Neuromonitoring System (CNS) is a portable, computer based system that can continuously record, display, store, and analyze physiological data from multiple monitoring sources in real-time. Electroencephalographic (EEG) data can be recorded from up to 16 electrode locations using the included EEG amplifier. Video can be recorded using an optional video camera. Other data can be recorded from interfaces to third-party monitoring devices, or can be manually entered. The CNS Monitor consists of the following main physical components: a color flat-panel touchscreen display, an integrated computer system, a Device Interface Module, and an EEG Arnolifier. All hardware components of the monitor are mounted on a wheeled pole stand to provide a compact design, convenient use, and ease of transportation. An Ethernet port is located at the base of the system to allow the archival of patient data to a network. A storage basket can hold electrone supplies, and can also hold the EEG amplifier when the system is not in use. The Device Interface Module contains six digital serial interfaces for connecting to external monitoring devices and four MDport™ (USB) interfaces used for connecting to other CNS components (such as the EEG Amplifier) or to electrically isolated, USB-based, external monitoring devices. The Device Interface Module also contains a CD/DVD drive for archiving patient recordings, for updating the system software, and for other data storage or retrieval purposes. The EEG Amplifier is small and lightweight and connects to the Device Interface Module with a flexible 15' cord. It has 19 inputs (including Reference, Ground, and auxiliary inputs) and can record from up to 16 EEG electrode sites. Up to 6 inputs can be used as differential pairs for other physiological signals (e.g.: ECG, EOG, respiration, etc.). Continuous impedance checking automatically detects any electrodes that become loose or detached. Data can be viewed on the CNS Monitor using a variety of display types: waveform, trend, numeric readout, compressed spectral array (CSA), and density spectral array (DSA). Combinations of multiple display types can be configured in a variety of screen layouts to allow the comparison of different measurements or different time periods from the recording. The CNS Monitor can compute processed parameters from the EEG data, including: Amplitude Integrated EEG (aEEG), Total Power, Spectral Edge Frequency, EEG Band Power Percentages (delta, theta, alpha, beta), Envelope Amplitude, % Asymmetry, % Suppression, and Inter-Burst Interval (IBI). The CNS Monitor also has several features to enable ease-of-use. It employs monitoring protocols that can step the user through a monitoring procedure and configure a group of settings for the recording (including EEG electrode sites & montage, collected measurements, and display settings). Pre-configured protocols are included on the system and the user can also create their own customized protocols. Embedded reference content can be viewed on the CNS Monitor to assist the user with system features, device connections, electrode application, and other topics.
