Indications for Use
The BIS EEG VISTA Monitor System is intended for use under the direct supervision of a licensed healthcare practitioner or by personnel trained in their proper use. The system, and all its associated parameters, is intended for use on adult and pediatric patients within a hospital or medical facility providing patient care to monitor the state of the brain by data acquisition of EEG signals. The BIS Index, one of the VISTA Monitor output parameters, may be used as an aid in monitoring the effects of certain anesthetic agents; and its usage with certain anesthetic agents may be associated with a reduction in primary anesthetic use and a reduction in emergence and recovery time. Use of the BIS Index for monitoring to help guide anesthetic administration may be associated with the reduction of incidence of awareness with recall in adults during general anesthesia and sedation.
Device Story
System comprises BISx4 digital signal converter, VISTA monitor, and cables. Connects to forehead-applied BIS sensors to acquire 2 or 4 channels of EEG signals. BISx4 performs digital signal processing and computes Bispectral Index (BIS), SQI, EMG, Burst Count, and Suppression Ratio; when using bilateral sensors, it calculates DSA, Asymmetry, sBIS, and sEMG. Monitor displays these parameters numerically and graphically with trend screens. Used in hospitals/medical facilities under supervision of licensed practitioners. Output assists clinicians in monitoring anesthetic effects and guiding administration to optimize anesthesia depth and recovery. BISx component functions as a standalone processor for integration into OEM patient monitoring systems.
Clinical Evidence
Bench testing only. Software validation and hazard analysis/risk assessment performed. No clinical data presented.
Technological Characteristics
EEG monitor system; digital signal processing; 2 or 4-channel EEG acquisition; BISx4 processor; connectivity via cables to patient sensors and monitors; software-based parameter computation; Class II device.
Indications for Use
Indicated for adult and pediatric patients in hospital/medical facilities to monitor brain state via EEG signal acquisition; aids in monitoring anesthetic agent effects and guiding anesthetic administration to potentially reduce primary anesthetic use, emergence/recovery time, and incidence of awareness with recall in adults during general anesthesia and sedation.
Regulatory Classification
Identification
An electroencephalograph is a device used to measure and record the electrical activity of the patient's brain obtained by placing two or more electrodes on the head.

#### Classification
Electroencephalograph (EEG) monitors have been classified by the Neurological Devices Panel as Class II devices (21 CFR 882.1400)
#### Predicate Device
Aspect Medical System's A-3000 EEG Monitor with BIS (#K052362), Spectral EEG Monitor A1000 (# K963644), Aspect Medical Systems BIS EEG Monitor VIEW (#K062613), Aspect Medical System's BISx4 (#K052981), Aspect Medical System's BISx (#K040183)

#### Device Description:
#### A. BIS EEG VISTA Monitor System:
The BIS EEG VISTA Monitor System, is comprised of the BISx4, the VISTA Monitor, and associated cables. When the System is connected to a BIS Sensor (which is applied to the patient's forehead, acquires EEG signals from the brain, and is 510(k) cleared) the monitor displays 2 channels of EEG. When the System is connected to a BIS Bilateral Sensor (also 510(k) cleared), the monitor displays 4 channels of EEG.
The BISx4 houses the digital signal converter as well as the BIS algorithm (it has no display or user interface), and it performs the computations necessary to produce the Bispectral Index (BIS). It also calculates SQI, EMG, Burst count and Suppression Ratio. The BISx4 may be distributed to business partners that have the ability to display BIS on their patient monitors.
The Monitor displays a maximum of 4 channels of EEG, as well as SQI, EMG, Burst Count, Suppression Ratio and a BIS value. The BIS value is acquired using 2 channels of EEG. The Monitor has secondary trend and trend review screens, as well as results of self tests.
In addition to the above, when connected to a Bilateral Sensor, the System provides additional capability as follows:
BISx4 calculates DSA, Asymmetry, sBIS, and sEMG. The Monitor displays DSA, Asymmetry, sBIS, and sEMG numerically and graphically.
#### B. BISx device:
The BISx is a component that processes up to 2 channels of EEG and computes BIS and other EEG parameters (same as the cleared BISx device). The BISx connects to Aspect sensors on one side and the Aspect Monitor or OEM patient monitoring systems on the other, allowing them to display BIS on their integrated patient monitoring systems. The OEMs are responsible for the regulatory pathway to integrate the BISx in their systems.
The software is a moderate level of concern. This submission is updating the indications for use statement for the BISx device, to reflect the addition of clinical benefits added at FDA request to the BIS EEG VIEW Monitor, 510(k) (K#062613, recently cleared on 6/18/07). No change is being made to the cleared BISx device (#K040183).
