The reprocessed Monarch Bronchoscope, used in conjunction with the Monarch Platform, is intended to provide bronchoscopic visualization of and access to patient airways for diagnostic and therapeutic procedures.

The 4x reprocessed Monarch Bronchoscope. MBR-000211-B. (hereafter referred to as "Proposed Device") is similar to the 2x reprocessed Monarch Bronchoscope, MBR-000211-B, (hereafter referred to as "Predicate Device").

The Original Monarch Bronchoscope. MBR-000211-A. (hereafter referred to as "Co-Predicate Device") cleared under K193534 is identical to the 2x reprocessed Monarch Bronchoscope ("Predicate Device"), cleared under K203614.

Both device designs are controlled by Auris Health, Inc., throughout their total product lifecycle.

The Monarch Bronchoscope is a component of, and must be used with, the Monarch Platform, cleared under K193534. The Monarch Bronchoscope is connected to the robotic arms of the Monarch Platform to provide bronchoscopic visualization of and access to patient airways for diagnostic and therapeutic procedures. The Proposed Device is a reprocessed single-use device that is either discarded or returned to Auris for reprocessing after clinical use. The original singleuse Monarch Bronchoscope was cleared for one clinical use under K193534. The reprocessed single-use (rSUD) Monarch Bronchoscope was cleared for two (2) clinical uses under K203614. This premarket notification intends to gain market clearance for a reprocessed single-use (rSUD) Monarch Bronchoscope that can be reprocessed up to three (3) times, for a total of four (4) clinical uses.

Identical to the Predicate Device, the Reprocessed Monarch Bronchoscope, consisting of the Inner Scope ("scope") and the Outer Sheath ("sheath"), has 4-way articulation controlled by continuous, direct, visual control of the physician using the Monarch Platform. The Proposed Device contains a working channel through which biopsy devices, or other working channel instruments, may be introduced. The distal tip of the Proposed Device has a camera control unit (CCU) that collects live images that are then transmitted to the physician's display interface of the Monarch Platform. The camera transmits vision data to the Monarch Tower through the camera cable. The single-use, manually controlled, working channel instruments compatible with the Proposed Device are identical to the working channel instruments compatible with the Predicate Device.

The provided text describes the regulatory clearance of a reprocessed medical device, the Monarch Bronchoscope, and its performance testing to demonstrate substantial equivalence to a predicate device. However, it does not contain specific acceptance criteria for a diagnostic algorithm, nor does it detail a study that proves a device meets such criteria in terms of diagnostic performance (e.g., sensitivity, specificity).

The document is a 510(k) premarket notification letter from the FDA, confirming clearance for the "4x reprocessed Monarch Bronchoscope" (meaning it can be reprocessed up to three times for a total of four clinical uses). The performance testing described focuses on the physical and functional integrity of the reprocessed device, not on diagnostic accuracy of an algorithm or an AI component.

Therefore, many of the requested items (e.g., acceptance criteria for diagnostic performance, sample sizes for test/training sets, expert qualifications, MRMC studies, standalone algorithm performance, type of ground truth) are not applicable or cannot be extracted from this document.

Here's an attempt to answer the questions based only on the provided text, highlighting where information is absent or not relevant to diagnostic algorithm validation:

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

The document provides a list of performance tests conducted for the reprocessed bronchoscope, with "Pass" as the result, indicating that the device met internal design specifications and applicable standards for safe and effective reprocessing. These are functional and safety-related criteria for the physical device, not diagnostic performance metrics.

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

This information is not provided in the document. The performance tests refer to "worst case device conditioning" but do not specify the number of devices or clinical cases used in these tests. The data provenance is not mentioned.

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)

This information is not applicable to the type of device and testing described. The document pertains to the reprocessing of a physical bronchoscope, not a diagnostic algorithm requiring expert ground truth for image interpretation or diagnosis.

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

This information is not applicable to the type of device and testing described. Adjudication methods are typically relevant for human-in-the-loop or diagnostic studies, which are not detailed here.

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

This information is not applicable to the type of device and testing described. The document does not mention an AI component or any MRMC studies.

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

The provided text describes performance data but does not specify quantifiable acceptance criteria for the Monarch® Platform, Urology device. Instead, it states that the device was tested against internal design specifications and applicable performance standards to demonstrate safety and effectiveness, and that "all intended user needs evaluated met their acceptance criteria." However, what those specific quantitative acceptance criteria were for different aspects (e.g., accuracy, reliability, image quality) and the reported performance against them are not detailed in the provided document.

Therefore, the following information is based on what can be extracted or inferred from the provided sections, recognizing the absence of explicit quantitative acceptance criteria and specific performance metrics for the device itself.

1. Table of Acceptance Criteria and Reported Device Performance

As mentioned above, the document does not provide a table of explicit acceptance criteria with specific quantitative targets and corresponding reported device performance values. The general statements are that all tests "Passed" or "met acceptance criteria."

Therefore, I cannot construct the requested table with specific numerical values for acceptance criteria and reported device performance.

2. Sample Size Used for the Test Set and Data Provenance

The document mentions "live porcine model" for Design Validation and "Acute Animal Safety" studies.

• Sample Size for Test Set: Not explicitly stated as a numerical count for either the Design Validation or Acute Animal Safety studies. The phrasing "live porcine model" and "live animal model" are general.
• Data Provenance: The studies were conducted using "live porcine model" and "live animal model," indicating animal testing (pre-clinical). The location or country of origin is not specified, but it suggests a controlled laboratory setting. The studies are prospective in nature, as they involve active testing and data collection.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

The document mentions "intended users" and "representative users" in the context of Human Factors and Usability evaluation and Design Validation. However, it does not specify the number of experts used to establish ground truth for any test set or their specific qualifications (e.g., "radiologist with 10 years of experience").

4. Adjudication Method for the Test Set

The document does not describe any adjudication method (e.g., 2+1, 3+1) for establishing ground truth for any test set. The term "ground truth" itself is not explicitly used in the context of expert review in the provided text.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs without AI Assistance

The document does not mention or describe a Multi Reader Multi Case (MRMC) comparative effectiveness study. The Monarch® Platform is described as a capital equipment platform with electromechanical articulation and control, and software for navigation, but there is no indication of an AI component designed to assist human readers in interpretation or diagnosis, nor any study comparing human performance with and without AI assistance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

The document describes the Monarch® Platform as a system that requires "continuous and direct physician control" and where "Device movement is only at the command of the physician." The software provides "optional navigation guidance." This indicates that the device is designed for human-in-the-loop operation, and the description does not support the idea of a standalone (algorithm-only) performance study.

7. The Type of Ground Truth Used

Based on the descriptions:

• Design Validation and Acute Animal Safety: The "ground truth" for these studies would implicitly be established through direct observation, physiological measurements, and potentially post-mortem examination in the animal models, assessing safety and functionality in a simulated use environment. This is a form of direct-measurement or observation-based ground truth specific to animal model performance.
• Other tests (Reprocessing, Sterility, Biocompatibility, Electrical Safety, Software, Verification Testing, Human Factors): These rely on adherence to established standards and internal specifications, where "ground truth" is defined by the objective pass/fail criteria of technical tests rather than expert consensus on diagnostic images or pathology.

8. The Sample Size for the Training Set

The document describes pre-market testing and validation for a medical device (Monarch® Platform, Urology). It does not mention a "training set" in the context of machine learning or AI, as the primary focus seems to be on the electromechanical system and software components rather than a learning algorithm that requires a training set.

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

As no "training set" for an AI/ML algorithm is mentioned, this question is not applicable based on the provided text.
