Intended Use

The VERABAND™ is a compact, lightweight, body-worn activity monitoring device designed to document physical movement associated with applications in physiological monitoring. The device is intended to monitor limb or body movements during daily living and sleep for a limited time interval (up to 30- days).

The VERABAND™ can be used to assess activity in any instance where quantifiable analysis of physical motion is desired. VERABAND™ is not intended for diagnostic purposes.

Device Description

The VERABANDTM is a compact, wrist-worn battery-operated wearable device intended for collecting a patient's motion data for assessing patient activity. VERABANDTM is intended to acquire and store data while being worn during normal activities and/or during sleep. The device consists of a wearable band with compact housing for battery-powered on-board electronics with an accelerometer. The recorded activity data is timestamped and stored in non- volatile memory for later retrieval. Downloaded VERABANDTM data can be post-processed based on the timestamp and magnitude of acceleration for reporting.

AI/ML Overview

Here's a breakdown of the acceptance criteria and study information for the Veraband™ device based on the provided FDA 510(k) summary:

2. Sample Size and Data Provenance (for test set, if applicable)

The document primarily describes non-clinical engineering and performance testing. It does not explicitly state a "test set" in the context of clinical data. For the "VERABAND™ intended use" test, it states "Simulated users wearing the device perform activities at different intensities of motion and wear compliance times." While it implies subjects, no specific sample size is provided. The data is non-clinical/simulated.

3. Number of Experts for Ground Truth and Qualifications (for test set, if applicable)

Not applicable, as the provided data focuses on non-clinical and simulated testing for performance validation rather than expert-derived ground truth for a test set of patient data.

4. Adjudication Method (for test set, if applicable)

Not applicable. The reported tests are primarily objective engineering and performance validations against predefined criteria, not subjective human evaluations requiring adjudication.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No. The document explicitly states: "The VERABAND™ did not require clinical studies to support substantial equivalence to the primary predicate device." Therefore, no MRMC study was conducted or reported.

6. Standalone (Algorithm Only) Performance Study

Yes, the majority of the reported testing falls under standalone performance. The "non-clinical testing summary" details various tests (e.g., accelerometer accuracy, battery life, sampling rate, frequency response, report generation comparison) that evaluate the device's technical functionality and performance in isolation or in comparison to a predicate device's output, without human-in-the-loop performance measurement.

7. Type of Ground Truth Used

For the non-clinical tests, the ground truth was based on:

  • Established engineering specifications and requirements (e.g., full-range accuracy, required light level, expected device life, minimum number of cleanings, sampling rate, full-scale dynamic range, predicate's bandwidth, repeatability and reproducibility for activity levels, predicate comparison requirements for output metrics).
  • Recognized consensus standards (e.g., IEC, ISO, ASTM).
  • Simulated motions and user activities.

8. Sample Size for the Training Set

The document does not mention a "training set" in the context of machine learning or AI. The device is described as an activity monitoring device with an accelerometer to acquire and store data, which is then post-processed. It doesn't appear to be an AI/ML-driven diagnostic device that would typically involve a training set for model development.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no mention of a "training set" for an AI/ML model. The device's operation relies on sensor data acquisition and processing based on established algorithms and engineering principles, not on a trained machine learning model.
