Here's an analysis based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria CategorySpecific Acceptance CriteriaReported Device Performance
Predicate Device EquivalenceThe Epi-Star system must be substantially equivalent to currently marketed predicate devices in terms of indications for use, design, methods of operation, physical construction, and functional/performance features.The Epi-Star system is stated to be exactly the same as the Nidek Dio-Light 60 Diode Surgical Laser System (K981447) except for the intended use for hair removal, and shares the same design, functional, and performance features. It is also compared to other legally marketed predicate devices and found to have the same or similar design, functional, and performance features.
Safety and EffectivenessThe device must be safe and effective for its indicated uses.The submission states that safety and effectiveness are reasonably assured, especially for hair removal, based on the information provided, and through design control procedures.
Regulatory ComplianceManufacturing and design must comply with 21 CFR 1040.10 and 1040.11 (FDA regulations for Medical Laser Products).The device is manufactured and designed to comply with these requirements.

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

No test set was described. The submission explicitly states "Clinical Performance Data: None presented" (Section VII) and "Non-Clinical Performance Data: None presented" (Section VIII). The basis for clearance is substantial equivalence to predicate devices, not direct testing on a new dataset.

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

Not applicable. No test set was used, and therefore no experts were required to establish ground truth for a test set.

4. Adjudication Method for the Test Set

Not applicable. No test set was used.

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 laser system, not an AI-powered diagnostic tool, and no MRMC study was conducted.

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

Not applicable. This is a laser surgical system, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

Not applicable in the context of device performance testing. The "ground truth" for this 510(k) submission is the established safety and effectiveness of the predicate devices to which the Epi-Star system is being compared.

8. The sample size for the training set

Not applicable. As this is a physical medical device (laser system) and not an AI/algorithm, there is no "training set" in the conventional sense.

9. How the ground truth for the training set was established

Not applicable. There is no training set for this device.

Summary of the Study Proving Acceptance Criteria:

The Nidek Epi-Star Diode Surgical Laser System gained regulatory clearance through the 510(k) pathway based on a demonstration of substantial equivalence to already legally marketed predicate devices, rather than through new clinical or non-clinical performance studies.

The core of the "study" demonstrating that the device meets acceptance criteria is a comparison of the Epi-Star's specifications and features against those of several predicate devices.

  • Rationale for Substantial Equivalence (Section IX): The submission argues that the Epi-Star is "exactly the same" as the Nidek Dio-Light 60 Diode Surgical Laser System (K981447) in methods of operation, physical construction, and design, functional, and performance features, with the only difference being the intended use for hair removal. It also asserts that the Epi-Star shares "the same or similar design, functional, and/or performance features" with other predicate devices (Coherent/Palomar LightSheer, Sharplan Lasers EpiTouch ALEX, Candela Corp. GentleLASE, Cynosure Inc. Photogencia LPIR).
  • Documentation: The comparison details are expected to be provided in "Appendix B, Substantial Equivalence Comparison" (though Appendix B is not included in the provided text).
  • Safety and Effectiveness Justification (Section X & XI): The safety and effectiveness are "reasonably assured" because the device is substantially equivalent to predicates that are already deemed safe and effective. Design control procedures (mentioned in Appendix E) and safety features (in Appendix D, "DEVICE DESCRIPTION") are also cited to ensure safe use.

In essence, the "study" is a document-based comparison that leverages the prior regulatory clearance and established safety/effectiveness profiles of similar devices already on the market. No new clinical trials or performance evaluations with human subjects or dedicated test datasets were conducted or presented for the Epi-Star device itself in this submission.

Rational for Substantial Equivalence IX

Comparison of system specifications between the Nidek Epi-Star Diode Surgical Laser System and the Nidek Dio-Light 60 Diode Surgical Laser System (K981447) are exactly the same, except for the intended use for hair removal. As both of these systems are the same in their methods of operation and physical construction, and both systems utilize the same design, functional, and performance features (as demonstrated in Appendix B), and are therefore substantially equivalent.

Comparison of system specifications and features of the Nidek Epi-Star Diode Surgical Laser System and the other legally marketed predicate devices demonstrates the systems to be equivalent. The systems compared all have the same or similar design, functional, and/or performance features (as demonstrated in Appendix B, Substantial Equivalence Comparison), and are therefore substantially equivalent.

Since the Nidek Epi-Star Diode Surgical Laser System is substantially equivalent with respect to the indications for use, design, methods of operation, physical construction, functional and performance features to other predicated devices, we believe that this device clearly meets the requirements for substantial equivalence according to the 510(k) guidelines.
