• Cerfolio et al. 2016: 8 patients
• Gonde et al. 2017: 10 patients
• Kneuertz et al. 2017: 20 patients
• Suda et al. 2014: 33 patients

The text does not explicitly state the country of origin for these clinical studies. It also doesn't specify if they were retrospective or prospective, though the nature of supporting clinical evidence often leans towards prospective or a mix. The phrase "real-world clinical evaluation" suggests observation in actual clinical settings.

For the bench/in vitro verification testing, the sample size is not quantified in terms of units tested, but it's stated that "extensive bench testing" was performed to confirm "all functional and performance attributes."

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

This information is not provided in the document. The clinical studies are referenced by author names and publication years, but details on how the ground truth (e.g., successful procedure, absence of complications) was established by experts, or the qualifications of those experts, are absent. The mention of "testimonial letter from the author" for Cerfolio et al. 2016 confirms the study's findings but doesn't detail the expert review process within the study itself.

4. Adjudication Method for the Test Set

The adjudication method for establishing ground truth in the clinical studies is not explicitly stated.

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

This aspect is not applicable to the SurgiQuest AirSeal iFS System. This device is an insufflation system, not an AI-powered diagnostic or assistive tool for human readers. Therefore, an MRMC comparative effectiveness study comparing human readers with and without AI assistance was not performed.

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

This aspect is not applicable. The SurgiQuest AirSeal iFS System is a physical medical device with software control, but it's not a standalone algorithm/AI system whose performance would be measured without human interaction. It's an instrument used by surgeons.

7. The Type of Ground Truth Used

For the clinical/in vivo testing, the ground truth appears to be based on clinical outcomes and observations during surgical procedures, specifically the successful use of the device without reported adverse events. This implies confirmation by the physicians performing the procedures.

For the bench/in vitro verification testing, the ground truth was established by meeting predefined engineering specifications and requirements for functional and performance attributes. Compliance with recognized industry standards also serves as a ground truth baseline for safety and performance characteristics.

8. The Sample Size for the Training Set

The document does not provide information regarding a "training set" in the context of machine learning or AI. The device contains software ("The device contains software"), but it is not described as an AI/ML device that requires a separate training set for its algorithms to learn. Its software likely orchestrates control functions (e.g., pressure regulation, mode switching) based on hard-coded logic and control loops, rather than learned patterns from a training dataset.

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

Since no training set for AI/ML is mentioned, this information is not applicable. The software's "ground truth" or correct functioning would have been established through traditional software verification and validation, ensuring it correctly implements its design specifications and requirements.

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of acceptance criteria with corresponding device performance metrics in the format typically used for AI/ML device evaluations (e.g., sensitivity, specificity, accuracy against a threshold). Instead, it discusses the device's adherence to various engineering and quality standards, and the results of a bench test demonstrating "substantial equivalence."

However, we can infer some "performance" from the bench test mentioned:

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

• Sample Size for Test Set: Not applicable in the context of this document. The study described is an "engineering in-vitro bench test," not a human clinical trial or a dataset of patient cases.
• Data Provenance: Not applicable. The "data" comes from an in-vitro bench test, not from patient data (e.g., country of origin, retrospective/prospective).

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

• This information is not provided in the document, as the "ground truth" for an engineering bench test is typically defined by the physical parameters being measured and the established performance of a predicate device, rather than expert consensus on medical images or diagnoses.
