Here's the breakdown of the acceptance criteria and the study proving the device meets them:

1. Table of Acceptance Criteria and Reported Device Performance:

The document primarily focuses on establishing substantial equivalence to predicate devices rather than defining explicit numerical acceptance criteria for a new clinical performance claim. Instead, the "acceptance" is demonstrated through comparative testing against established predicate performance.

Acceptance Criteria (Demonstrated through Equivalence)Reported Device Performance (StealthConnect System)

User Authorization and Authentication: Requires user authentication and log-on capabilities.Requires user authentication and log-on capabilities, integrating with hospital credentialing systems (LDAP/AD).

2. Sample Sizes Used for the Test Set and Data Provenance:

The document does not specify precise sample sizes (e.g., number of cases or patients) for the "test set" in the context of a typical AI/ML study. The performance testing described suggests a verification and validation approach rather than a large-scale clinical test set.

  • Test Set Sample Size: Not explicitly stated as a number of cases or patients. The tests are described as "laboratory and simulated use settings."
  • Data Provenance: Not explicitly stated (e.g., country of origin). Given Medtronic's presence and the FDA 510(k) submission, it is highly likely the testing was conducted in the US or under US-equivalent standards. The testing was performed in "laboratory and simulated use settings," implying synthetic or internal data, or potentially clinical data within Medtronic's environment, but not specified. The study is retrospective in nature as it is a verification and validation of a device's performance against pre-established requirements or predicate device performance, not a prospective trial to gather new efficacy data.

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

The document does not mention the use of experts to establish a "ground truth" in the typical sense for a diagnostic device. The device is for planning and collaboration, not primary diagnosis. The accuracy and display effectiveness testing would likely have used quantitative measurements or comparisons against the predicate device's output, rather than expert consensus on a diagnostic outcome. For instance, the "Accuracy testing for planning components" would compare the StealthConnect's output (e.g., calculated positional/trajectory error) to the known/expected values or those of the predicate device, not against expert labels of medical conditions.

4. Adjudication Method for the Test Set:

Not applicable. Since there's no mention of expert readers assessing "ground truth" for diagnostic outcomes, there's no adjudication method described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:

No, a MRMC comparative effectiveness study was not done. The document describes verification and validation testing, including "Display Effectiveness testing" to show sufficiency for planning, and accuracy testing comparative to the predicate, but not a study to quantify human reader improvement with AI assistance. The device is an accessory for planning and collaboration, not an AI diagnostic tool intended to assist human readers in image interpretation for primary diagnosis.

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

Yes, in a way. The "performance testing" described (e.g., "Accuracy testing for planning components" and "Functional testing of the PureWeb component") assessed the device's functional performance independently of human interaction, as it aimed to verify that the software and its components perform as intended. However, the device's overall intended use inherently involves human interaction (professionals using it for viewing, planning, and collaboration). There isn't a direct "standalone diagnostic performance" report as typically seen for AI image analysis algorithms.

7. The Type of Ground Truth Used:

The "ground truth" for this device's performance assessment appears to be:

  • Predicate Device Performance: For accuracy (e.g., positional and trajectory error) and display effectiveness, the performance was compared to the predicate StealthStation Cranial v 3.0.
  • Design Requirements/Specifications: The testing was conducted to ensure the product performs "as intended according to the outlined design requirements."
  • Established Industry Standards: Usability testing was conducted in accordance with IEC 62366.
  • Functional Equivalence: For components like PureWeb, the "ground truth" was its known functionality as part of the ResolutionMD predicate.

There is no mention of pathology or outcomes data being used for ground truth.

8. The Sample Size for the Training Set:

Not applicable. The document describes a traditional software verification and validation process for a medical device that established substantial equivalence to predicate devices. It does not describe an AI/Machine Learning model that required a "training set." The "PureWeb component" mentioned is a primary component of a predicate device (ResolutionMD), implying it's a developed software part, not an AI model that undergoes training on data.

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

Not applicable. As stated above, there is no indication that this device developed or utilized an AI/Machine Learning model that required a training set or associated ground truth labeling.
