The Bio-logic Evoked Potential (EP) product family is indicated for use in the recording and analysis of human physiological data necessary for the diagnosis of auditory and hearing-related disorders. This product, the ABaer Cub, like it's predicate device, the ABaer, is especially indicated for use in the screening of infants to determine hearing loss. The Bio-logic EP System can be used for patients of all ages, from children to adults, including infants and geriatric patients. It is especially indicated for use in testing individuals for whom behavioral audiometric results are deemed unreliable, such as infants, young children, and cognitively impaired or uncooperative adults. The use of the Bio-logic EP family of products is to be performed under the prescription and supervision of a physician or other trained health care professional.

Device Story

ABaer Cub is a portable, battery-powered evoked response system for auditory screening. It records human physiological data to assist in diagnosing hearing disorders. The device uses a Digital Signal Processor (DSP) for real-time signal acquisition and processing, employing the Point Optimized Variance Ratio (POVR) algorithm to monitor signal-to-noise ratios and optimize signal quality. Input consists of physiological signals; output includes automated Pass/Refer screening recommendations and raw data for clinician review. Operated by nurses, audiologists, or physicians in clinical settings, the system interfaces with a PDA (e.g., HP Jornada) running Windows CE for display and control. The device enhances portability compared to the predicate by integrating battery power and PDA-based host control. Clinicians use the output to support diagnostic decisions; the system allows manual review/override of automated results.

Clinical Evidence

No clinical data provided. Safety and effectiveness established through design controls, hazard/risk analysis (Fault Tree Analysis per EN-1441), and bench testing of hardware/software modifications to ensure performance equivalence to the predicate device.

Technological Characteristics

Portable, battery-powered evoked response auditory stimulator. Features a Digital Signal Processor (DSP) for real-time data acquisition and POVR algorithm execution. Host interface via PDA (Windows CE). Patient isolation methods consistent with predicate. Materials and hardware design are substantially similar to the predicate, with added battery charging circuitry and enclosure modifications for portability. Software developed in C++.

Indications for Use

Indicated for recording/analysis of human physiological data for diagnosis of auditory/hearing disorders. Especially indicated for infant hearing screening. Suitable for all ages, including children, adults, geriatric patients, and individuals where behavioral audiometry is unreliable (e.g., cognitively impaired or uncooperative patients).

Section 2

The ABaer Predicate Device performs Evoked Potential screening, recording and analysis functions, provides one channel of data recording, and includes the Point Optimized Variance Ratio (POVR) algorithm for optimizing signal quality, implementing the screening function and enhancing speed of test completion. This new ABaer Cub device performs these same functions in essentially the same ways, but has hardware and software modifications and improvements over the Predicate device, primarily to enhance portability and ease of use.

The Predicate Device describes the use of the POVR algorithm to monitor the signal-to-noise ratio of the averaged response signal every 256 stimulation-response cycles. This modified device, ABaer Cub, incorporates the same POVR algorithm for the same purpose, to yield highquality test results in the shortest possible time. In addition, the feature modifications for this new device include the use of a Personal Digital Assistant (PDA) or "Pocket PC" which can be hand-carried separately or mounted right on the ABaer box, resulting in a completely batterypowered, portable hand-held test instrument. The Predicate Device uses a desktop or laptop computer instead of the PDA. The electronic hardware is very similar in design to the ABaer hardware used in the Predicate Device. The enclosure has been made slightly larger (deeper) to allow space to incorporate a rechargeable battery inside the unit. New circuitry for charging the battery has also been added to the unit, and the small LCD display in the ABaer has been removed from the ABaer Cub. The functions of the hardware are substantially the same as those of the Predicate Device hardware. The ABaer predicate device communicates test information and results to a separate host computer (desktop PC or laptop) through a serial communications port. In the ABaer Cub, this host computer is now a PDA or "pocket PC" (for instance, the Hewlett-Packard Jornada) which can be affixed right on the ABaer unit or hand-carried separately. Because both the PDA and the ABaer unit are battery powered, this significantly improves the portability and usability of the device. The ABaer Cub software for control of this device is a simplified subset of the ABaer Predicate Device software, with some GUI changes necessary to enhance the graphics display for use with the smaller PDA LCD screen. The host software for the Predicate Device is Windows 95/98/ME based, whereas the host software for the ABaer Cub is Windows CE based. The C++ programming language is used in both cases. Together, these minor hardware and software changes implement the same functionality and perform the same intended use as the Predicate Device, but with improved portability and easeof-use.

#### INTENDED USE:

The Bio-logic Evoked Potential (EP) product family is indicated for use in the recording and analysis of human physiological data necessary for the diagnosis of auditory and hearing-related disorders.

This product, the ABaer Cub, like it's predicate device, the ABaer, is especially indicated for use in the screening of infants to determine hearing loss.

The Bio-logic EP System can be used for patients of all ages, from children to adults, including infants and geriatric patients. It is especially indicated for use in testing individuals for whom behavioral audiometric results are deemed unreliable, such as infants, young children, and cognitively impaired or uncooperative adults. The use of the Bio-logic EP family of products is to be performed under the prescription and supervision of a physician or other trained health care professional.

Special 510(k): ABaer Cub, Device Modification to Bio-logic Evoked Potential Product

## SAFETY AND EFFECTIVENESS SUMMARY

To establish the safety and effectiveness of this modification to the Bio-logic Evoked Potential software, the modification was designed and incorporated into the product in accordance with the Bio-logic internal Product Development procedures which are intended to meet ISO-9001, EN-46001 and FDA QSR Design Control specifications. A detailed Hazard/Risk analysis for the EP family of products was performed using the Fault Tree analysis (FTA) approach, and a detailed Risk Assessment was written in accordance with EN-1441, the International Standard for Hazard/Risk analysis. An addendum to this Hazard/Risk file was written based on a review of this new ABaer Cub design.

The ABaer Cub patient-connection hardware is basically the same as that of the ABaer. There are no newly-introduced hardware-related methods by which the patient can be harmed or injured through the use of this device. The same patient isolation methods are used in both products. Both devices utilize a medical-grade power supply, although the ABaer Cub will be used most often in its portable, battery-operated mode. Direct hardware control of all ABaer Cub functions is provided from the Digital Signal Processor (DSP) and its program code located inside the ABaer Cub package, just as it is in the ABaer. By distributing the hardware-specific functions to the DSP, the Windows-based host computer program has fewer real-time demands, resulting is high reliability and performance.

Nurses, audiologists, and physicians can use the ABaer Cub system. No knowledge of or training in Evoked Potentials is necessary. Anyone, even a user with limited computer skills, who has been trained to operate this equipment and trained in techniques for proper infant handling, can use the ABaer Cub effectively.

The ABAER Cub software does not make any final decisions that result in any direct forms of diagnosis or treatment. The Pass/Refer recommendations of the automated screening process in the ABaer Cub can be reviewed, if desired, by a qualified health care professional, and may be modified, overridden or deleted as determined by the qualified user. The program provides additional functionality to allow the qualified user to review all raw data collected, and to perform other data analysis to suit his or her requirements. This optional data review capability allows the Physician to view the same data that the ABaer Cub used to make its recommendations.

The chart on the following page provides a summary comparison of the technological characteristics of the new ABaer Cub device relative to the predicate ABaer device. This is to demonstrate that this new ABAER Cub device has no significant differences which would adversely affect product safety and effectiveness.
