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.

The Monarch Platform and its accessories are intended to provide bronchoscopic visualization of and access to patient airways for diagnostic and therapeutic procedures.
The Monarch Platform is intended to provide bronchoscopic visualization of and access to patient airways for diagnostic and therapeutic procedures. The Monarch Platform enables robotic electro-mechanical articulation and precise control of a flexible bronchoscope under continuous and direct control by a physician operator. The Monarch Platform allows for precise access of the lung anatomy and continuous visualization using the bronchoscope distal tip camera.
The Monarch Platform consists of three major components, (1) Monarch Cart, (2) Monarch Tower, and (3) Monarch Bronchoscope, and working channel instruments and accessories. The Monarch Cart provides support for the robotic arms. It includes up to three robotic arms and the electronic systems required to power and operate the robotic system. The flexible Monarch Bronchoscope has a working channel and a camera at the tip. The working channel of the Bronchoscope is used for irrigation, aspiration and to deliver the working channel instruments.
Additionally, the Monarch Platform includes electromagnetic (EM) navigation that integrates a pre-operative computed tomography (CT) scan into an intra-operative interface. displaying the modeled bronchoscope tip location relative to the preoperative scan anatomy. Two options of field generators are available to enable electromagnetic navigation. The current Monarch Navigation Field Generator and a new Window Field Generator (WFG). The new WFG is being added to increase compatibility of the Monarch system with advanced imaging systems (Cone Beam and Mobile CT).
Here's an analysis of the provided text regarding the Monarch Platform's acceptance criteria and study information:
Device Acceptance Criteria and Performance Study Analysis
The document describes the Monarch Platform, a robotic bronchoscopy system. The premarket notification (K211493) focuses on modifications to an existing cleared device (K193534), specifically the introduction of a "Window Field Generator (WFG)" as an optional accessory and minor software changes. Therefore, the performance data presented is primarily to demonstrate that these changes do not raise new questions of safety or effectiveness compared to the predicate device.
1. Table of Acceptance Criteria and Reported Device Performance
The document does not provide a formal table of quantitative acceptance criteria with specific thresholds (e.g., accuracy > 95%). Instead, it generally states that the device was tested to ensure it performs "as intended" and that changes "do not raise different questions of safety or effectiveness."
Here's a summary of the reported device performance based on the general statements:
| Aspect Tested | Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|---|
| Overall System Performance | Performs as intended, no new safety/effectiveness questions raised by modifications. | "Overall, device performance testing showed that the differences in technological characteristics do not raise different questions of safety or effectiveness." |
| Electrical Safety | Meets relevant electrical safety standards. | "Verification testing included electrical safety..." |
| Electromagnetic Compatibility (EMC) | Meets relevant EMC standards. | "...and electromagnetic compatibility..." |
| Software Functionality | Software changes operate correctly and do not introduce new risks. | "...software, and performance specifications verification testing." (Specifically mentions "minor software changes" including arm kinematics, smoother virtual views, new 'Segmentation Failure' notification trigger, and reduced red saturation in live endoscopy view.) |
| Window Field Generator (WFG) Functionality | Performs the same function as the existing Monarch Field Generator, with increased mechanical compatibility. | "This new WFG has the same core technological characteristics as the current Monarch Field Generator but is secured under the patient bed to optimize mechanical compatibility. Both EM field generators perform the same function for the Monarch Platform." |
| Clinical Input Requirements (CIR) | Meets defined CIRs for its intended use. | "confirmatory validation testing was performed to ensure the device meets its Clinical Input Requirements (CIR) for its intended use." |
| Impact on Workflow | Modifications do not negatively impact the pertinent parts of the workflow. | "Validation Testing included evaluations of the pertinent parts of workflow impacted by this change with accredited bronchoscopists." |
2. Sample Size and Data Provenance
The document does not specify the sample size used for the test set. It mentions "evaluations of the pertinent parts of workflow impacted by this change with accredited bronchoscopists," but provides no numbers for patients, cases, or procedures.
The data provenance is not explicitly stated as retrospective or prospective, nor is the country of origin. Given the context of a 510(k) submission for a medical device cleared in the U.S., it's highly likely the data would come from U.S. clinical settings, but this is an inference.
3. Number and Qualifications of Experts
The document states that "accredited bronchoscopists" were involved in the "Validation Testing including evaluations of the pertinent parts of workflow." It does not specify the number of experts or their years of experience/specific qualifications beyond being "accredited bronchoscopists."
4. Adjudication Method
The document does not describe any specific adjudication method (e.g., 2+1, 3+1, none) for the test set or for establishing ground truth.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No mention is made of a multi-reader multi-case (MRMC) comparative effectiveness study comparing human readers with and without AI assistance. The study described focuses on verifying the safety and effectiveness of device modifications rather than assessing the AI's impact on human reader performance.
6. Standalone Performance (Algorithm Only)
The document does not explicitly state that a standalone (algorithm only without human-in-the-loop performance) study was done for the navigation updates. The "navigation was updated for smoother virtual views when transitioning between predicted airways" and "An additional condition for which a "Segmentation Failure" notification would be triggered" suggest algorithm internal testing, but no formal standalone performance study results are provided in the summary. The Monarch Platform is an integrated robotic system where the navigation is an aid to the physician, not a standalone diagnostic tool.
7. Type of Ground Truth Used
The type of ground truth for the device's performance, particularly for the navigation and segmentation aspects, is not explicitly defined. However, given the context of bronchoscopic visualization and access, the "ground truth" for the device's ability to maintain its intended function would likely involve:
- Imaging data: Pre-operative CT scans are used for EM navigation, and live endoscopy views provide real-time visualization.
- Expert assessment: "Accredited bronchoscopists" evaluated workflow, implying their professional judgment against clinical standards would serve as a form of ground truth for usability and functional performance.
- Engineering specifications: Performance verification against design specifications would constitute a ground truth for many technical aspects.
Pathology or extensive outcomes data are not mentioned as being used for the performance testing described.
8. Sample Size for the Training Set
The document does not provide any information regarding the sample size for a training set. This is because the submission is for modifications to an already cleared device, and the focus is on verification and validation of the changes, not a de novo AI algorithm development where training data would typically be detailed.
9. How Ground Truth for the Training Set Was Established
Since no training set information is provided, there is no information on how its ground truth would have been established.

The performance data section focuses on general device functionality, safety, and usability.
Therefore, many of the requested elements for AI/ML performance studies cannot be extracted from this document, as it describes a robotic-assisted bronchoscope rather than an AI-powered diagnostic tool.
However, I can extract information related to the general performance testing and ground truth establishment for the device's functionality:
1. A table of acceptance criteria and the reported device performance
The document does not provide a formal table of acceptance criteria with specific quantitative performance metrics typically associated with AI/ML diagnostic devices (e.g., sensitivity, specificity, AUC). Instead, it describes general verification and validation testing outcomes.
| Acceptance Criteria (Inferred from testing descriptions) | Reported Device Performance |
|---|---|
| Biocompatibility requirements per ISO 10993-1 | Met |
| EMC compliance and electrical safety per AAMI/ANSI ES60601-1, IEC 60601-1-2, IEC 60601-1-6, and IEC 60601-2-18 | Fully evaluated and tested, found compliant |
| Overall functionality (pre-operative planning, workflow, latency, functional safety, irrigation/aspiration, general functionality) | Conforms to design specifications, meets intended user needs, satisfied all sub-system specifications, exhibits electrical, mechanical, and functional integrity |
| User needs and safety/effectiveness under simulated use clinical conditions | Design meets intended user requirements and facilitates safe and effective use |
| Safe and effective use by representative users during a simulated bronchoscopy procedure after training | Assessed as safe and effective |
2. Sample size used for the test set and the data provenance
- Test Set Sample Size: Not explicitly stated for specific quantitative metrics or AI model evaluation. The document mentions "animal and cadaver testing" and "simulated use testing."
- Data Provenance: Not specified. Animal and cadaver testing
and simulated use testing are mentioned, implying experimental data rather than patient data from a specific country. This is prospective testing in a controlled environment.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable to this type of device submission's performance data. The device's "performance" here refers to its mechanical and functional integrity and usability, not diagnostic accuracy requiring expert ground truth in the traditional sense. The "user needs" and "safe and effective use" would implicitly involve clinical experts as testers/evaluators.
4. Adjudication method for the test set
Not applicable. The performance testing described is mechanical, electrical, and usability verification, not a clinical trial requiring adjudication of diagnostic outcomes.
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
Not applicable. This device is a robotic-assisted bronchoscope, not an AI diagnostic tool. No AI component is described as assisting human readers in interpreting medical images or data. The "AI" in this context refers to robotic control and electromagnetic navigation, not diagnostic decision support.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a human-controlled robotic system. Its function inherently involves a human operator ("physician operator").
7. The type of ground truth used
The "ground truth" for the verification and validation tests are:
- Biocompatibility: Established by adherence to ISO 10993-1 standards and the results of specific biological evaluations.
- Electrical Safety and EMC: Established by compliance with international standards (AAMI/ANSI ES60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-2-18).
- System Level Tests: Established by meeting predefined "design input requirements" and "sub-system specifications."
- Validation Testing (Animal/Cadaver): Established by the device meeting "intended user requirements" and facilitating "safe and effective use" in simulated clinical scenarios. This is essentially functional ground truth based on simulated procedural outcomes.
- Human Factors and Usability Testing: Established by the device being assessed for "safety and effective use" by representative users in simulated procedures, likely against predefined usability objectives.
8. The sample size for the training set
Not applicable. This device is described as a robotic platform for physical procedures, not an AI/ML model that requires a training set of data.
9. How the ground truth for the training set was established
Not applicable. As no AI/ML training set is described.
