Intended Use

The Vivo 200 DPS VivoScan™ Version 2.0 is indicated for use when it is necessary for a trained health care professional (for example an Audiologist) to measure or determine cochlear function by measuring, recording and displaying otoacoustic emissions. This device does not measure hearing, but helps to determine whether or not a hearing loss may be present, requiring further evaluation.

The Vivo 200 DPS VivoScan™ Version 2.0 does not measure hearing per se, but measures whether or not the cochlear hair cells are functioning. This device does not determine hearing levels, but allows the operator to establish specific pass or refer criteria.

The Vivo 200 DPS VivoScan™ Version 2.0 is indicated for patients of all ages from newborn through adults, to and including geriatic patients. The otoacoustic emissions test 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 Vivo 200 DPS VivoScan™ Version 2.0 is a prescription device. The labeling instructions and user operations are designed for trained professionals.

Device Description

Vivo 200 DPS™ Version 2.0 is a diagnostic system that assists clinical professionals in the assessment and screening of cochlear function. The device includes a probe with a disposable tip that fits in the patient's ear canal. The probe contains a tiny speaker for stimulating the patient's ear with sound and a microphone for receiving low-volume otoacoustic emissions (OAEs).

The probe is connected to a probe adaptor circuit that generates the acoustic stimuli and amplifies the OAE responses. The probe adaptor circuit initiates stimulus delivery under the control of a dedicated notebook computer. The notebook computer reads the response from the probe adaptor and processes the signal digitally to measure and detect the OAE signal level, estimate the noise and display the results.

The Vivo 200 DPS™ Version 2.0 probe adaptor is capable of producing stimuli and eliciting Transient Evoked OAEs (TEOAEs) and Distortion Product OAEs (DPOAEs). TEOAEs are produced by the cochlea in response to short duration click sounds. DPOAEs are produced in response to two continuous pure tones that are close to each other in frequency.

The Vivo 200 DPS™ Version 2.0 software contains digital signal processing algorithms for measuring and detecting responses to both types of OAEs. The DPOAE and TEOAE responses are acquired and detected using the same probe. probe adaptor circuit and computer interface. The stimuli for both types of OAEs use the same probe, amplification circuitry and computer interface but utilize different modules in the probe adaptor circuit to generate their respective waveforms.

Software running on the notebook computer under the Windows XP™ operating system incorporates a graphical user interface that allows the user to configure the OAE test protocol, initiate and stop the test, print, save and review test results, and store patient information.

AI/ML Overview

The provided document, K033108, is a 510(k) Summary for the Vivo 200 DPS VivoScan™ Version 2.0 OAE Audiometer. It primarily focuses on demonstrating substantial equivalence to a previously marketed device rather than providing detailed acceptance criteria and a comprehensive study report with specific performance metrics.

Based on the information provided in the document, here's a breakdown of the requested information:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state specific, quantifiable acceptance criteria (e.g., minimum sensitivity, specificity, accuracy, or specific response levels) for the Vivo 200 DPS VivoScan™ Version 2.0. The primary "performance" discussed is its substantial equivalence to a predicate device.

The main change in this version is the addition of Transient Evoked Otoacoustic Emissions (TEOAE) functionality. The "Software algorithm" comparison parameter notes:

Comparison ParameterDifference
Software algorithmThe propriety code in the VIVO 200DPS Version 2.0 uses averaging and Fast Fourier Transform (FFT) to process Transient Evoked Otoacoustic Emissions (TEOAE).

This indicates the method used for TEOAE processing, but not its performance against a specific criterion. The document also states that the device "is designed to meet the EN 60601 series of standards for electromagnetic (EMI) and electrical safety," which are safety and electrical performance standards, not diagnostic performance acceptance criteria.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

The document does not provide details about a specific test set, its sample size, data provenance, or study type (retrospective/prospective) for evaluating the diagnostic performance of the Vivo 200 DPS VivoScan™ Version 2.0. The submission is a 510(k) for substantial equivalence, which often relies on demonstrating that the new device does not raise new questions of safety and effectiveness compared to a predicate device, sometimes without new clinical studies if the changes are minor.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

Since no specific test set or study validating diagnostic performance is detailed, there is no information provided on the number or qualifications of experts used to establish ground truth.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

Given the lack of a detailed performance study with a test set, no adjudication method is mentioned.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

The document does not mention any MRMC comparative effectiveness study or any AI component that would assist human readers. The device is described as a diagnostic system that assists clinical professionals by measuring, recording, and displaying otoacoustic emissions, implying it's a measurement tool rather than an AI-assisted diagnostic aid in the modern sense.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

While the device includes "digital signal processing algorithms" for measuring and detecting responses, the document does not describe a standalone performance study of these algorithms in isolation (i.e., algorithm only without human-in-the-loop performance as a diagnostic tool). The device is intended for use by a "trained health care professional."

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Since no specific performance study with a test set is described, the type of ground truth used is not mentioned.

8. The sample size for the training set

The document does not describe a training set sample size. This type of information is typically related to machine learning models, which are not explicitly detailed as a primary component of this device beyond "digital signal processing algorithms."

9. How the ground truth for the training set was established

As no training set is described, how ground truth for a training set was established is not provided.

Summary of what is present in the document:

The 510(k) summary primarily asserts substantial equivalence to a predicate device, noting the addition of TEOAE functionality using digital signal processing algorithms (averaging and FFT). It defines the device's intended use and patient population. It does not provide details of clinical studies, performance metrics, acceptance criteria, or ground truth establishment typically found in submissions with novel diagnostic algorithms requiring such validation. The focus is on demonstrating that the updated device is safe and effective in a manner similar to its predecessor.
