UE BRONCHO Single-Use Bronchoscope: The UE BRONCHO Single-Use Bronchoscopes has been designed to be used with the UE Display, endotherapy accessories and other ancillary equipment for endoscopy within the airways and tracheobronchial tree. The UE BRONCHO Single-Use Bronchoscopes is for use in a hospital environment. The UE BRONCHO Single-Use Bronchoscopes is single-use device designed for use in adults.

UE Display: The UE Display is reusable digital monitor, intended to display live imaging data from UE Medical visualization devices.

The bronchoscope system consists of UE BRONCHO Single-Use Bronchoscopes and UE Display. The UE BRONCHO Single-Use Bronchoscopes (the bronchoscopes) are sterile, single-use flexible video bronchoscopes available in three sizes (Slim, Regular, Large). The bronchoscopes have been designed to be used with the UE Display (reusable, non-sterile), endotherapy accessories and other ancillary equipment for endoscopy within the airways and tracheobronchial tree. The bronchoscope system is designed for use by adults in a hospital environment.

The provided FDA 510(k) clearance letter details the clearance of the UE BRONCHO Single-Use Bronchoscopes and UE Display. However, it does not contain specific acceptance criteria or details of a clinical study that demonstrates the device's performance against such criteria. The document explicitly states "Clinical study: Not applicable."

The clearance is based on non-clinical data, specifically performance testing and compliance with voluntary standards, which demonstrates substantial equivalence to a predicate device (Ambu® aScope™ 4 Broncho, Ambu® aView™ Monitor - K173727).

Therefore, I cannot populate the requested table and answer questions 2-9 with the provided text. The document refers to "bench performance testing" which includes optical performance, color reproduction, geometric distortion, resolution, depth of field, image intensity uniformity, noise, dynamic range, and frame rate, comparing these aspects with the predicate device. However, it does not specify quantitative acceptance criteria for these tests nor provide the reported device performance against such criteria in the detail requested.

Here's an attempt to populate the table and address the questions based only on the information available in the provided text. Where information is missing, it will be stated as "Not provided in the text."

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample size used for the test set and the data provenance

Not provided in the text. The document refers to "bench performance testing" which typically uses a limited number of physical units or simulated conditions, rather than a "test set" of patient data as might be relevant for AI/ML devices. No human patient data was used for testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable, as no clinical study or expert-based ground truth establishment for a test set is mentioned. The testing was non-clinical bench testing.

4. Adjudication method for the test set

Not applicable, as no clinical study involving expert interpretation or adjudication 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

No. The document explicitly states "Clinical study: Not applicable." Therefore, an MRMC study was not performed. This device is a bronchoscope system, not an AI-assisted diagnostic tool.

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

Not applicable. This device is a bronchoscope system. While it has software and display capabilities, it is not an algorithm that performs a diagnostic or analytical function independently of a human operator, and no standalone performance study in this context was mentioned.

7. The type of ground truth used

For the non-clinical bench tests (e.g., optical performance, physical dimensions, electrical safety), the "ground truth" would be established by direct physical measurements, adherence to engineering specifications, and compliance with recognized international standards (e.g., ISO 8600, IEC 60601 series, ISO 10993 series). There is no "ground truth" in the clinical sense (e.g., pathology, outcomes data, expert consensus) as no clinical studies were performed.

8. The sample size for the training set

Not applicable. This device is a bronchoscope system and not an AI/ML device that requires a training set of data for model development.

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

Not applicable, as no training set was used.
