Important Note: The provided document is a 510(k) summary for a VersaOne™ Bladeless Trocar, a surgical instrument. It is NOT an AI/ML medical device submission. Therefore, many of the typical acceptance criteria and study elements associated with AI/ML systems (such as sample size for test/training sets, expert ground truth, MRMC studies, standalone algorithm performance, and training set ground truth establishment) are not applicable to this type of device. The document focuses on demonstrating substantial equivalence to a predicate device through engineering performance testing and biocompatibility.

Acceptance Criteria and Device Performance for VersaOne™ Bladeless Trocar

Since this is a traditional medical device (trocar), the "acceptance criteria" are not based on metrics like accuracy, sensitivity, or specificity as seen in AI/ML systems. Instead, they are comparative performance metrics against a predicate device and adherence to relevant standards.

1. Table of Acceptance Criteria and Reported Device Performance

The device's performance is demonstrated through comparative testing against its predicate, the VersaOne™ Bladeless Trocar (K151548), and adherence to standards.

Conclusion: The regulatory submission asserts that "The results of testing demonstrated the modified VersaOne™ Bladeless Trocar 8mm is substantially equivalent to the legally marketed device."

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

This information is not provided in the 510(k) summary. For a traditional device, "sample size" would refer to the number of devices or test repetitions in bench-top and animal studies. Data provenance (country, retrospective/prospective) is also not specified, as the studies are likely internal engineering and animal model testing, not human clinical trials.

3. Number of Experts Used to Establish Ground Truth and Qualifications

Not applicable for this type of device submission. Ground truth for an AI/ML system involves expert labeling of data. For a surgical instrument, "ground truth" is established through engineering specifications, validated test methods, and compliance with industry standards.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods like 2+1 or 3+1 are used in AI/ML studies for resolving discrepancies in expert labeling. For this device, performance is measured against objective engineering parameters and physical tests.

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

No, an MRMC study was not done. MRMC studies are specific to evaluating the impact of AI on human reader performance, which is not relevant for a surgical trocar.

6. If a Standalone Performance (Algorithm Only Without Human-in-the Loop) was Done

No, a standalone performance study was not done. This concept applies to AI algorithms operating independently, not to a physical surgical instrument. The performance testing described (bench top, animal) assesses the physical characteristics and function of the device itself.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance is established through:

• Engineering Specifications and Design Requirements: The device must meet predefined physical dimensions, material properties, and functional performance targets.
• Predicate Device Performance: The modified device must perform equivalently to its legally marketed predicate.
• Compliance with Standards: Adherence to international standards like ISO 11135 (sterilization) and ISO 10993-1/7 (biocompatibility and EO residuals).

8. The Sample Size for the Training Set

Not applicable. This device does not use machine learning, so there is no "training set."

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

Not applicable. As there is no training set, there is no corresponding ground truth establishment process.
