Device Description

The Holinwon 30 Laser System is a pulsed solid-state Holmium:YAG laser system is designed to deliver infrared laser energy with a wavelength of 2100 nm and a nominal pulse width of 600 microseconds. Menu driven control options allows the operator to select the pulse energy and the pulse repetition rate(frequency).

AI/ML Overview

The provided document is a 510(k) Premarket Notification for the Holinwon 30 laser system. This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, rather than proving safety and efficacy through clinical trials with pre-defined acceptance criteria and statistically significant results.

Therefore, the document does not contain the information requested regarding acceptance criteria and a study that proves the device meets those criteria in the context of typical clinical performance studies for novel devices (e.g., diagnostic accuracy studies for AI). Instead, it focuses on non-clinical bench testing and comparison to a predicate device.

Here's an explanation of why the requested information is not present and what is reported in the document:

  1. A table of acceptance criteria and the reported device performance: This document does not present clinical performance acceptance criteria or report performance data against such criteria. The "performance" reported are the results of non-clinical bench tests (electrical safety, EMC, software validation, biocompatibility) demonstrating compliance with recognized standards.

    However, for the sake of illustrating the comparison to the predicate device, which is the core of a 510(k) submission for substantial equivalence, a table can be constructed from page 7:

    The "acceptance criteria" here is that the differences in these characteristics "do not raise any new safety and effectiveness issues."

  2. Sample sized used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective): Not applicable for this type of submission. The "tests" mentioned are non-clinical bench tests (electrical safety, EMC, software validation, biocompatibility), not clinical studies with patient data.

  3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience): Not applicable. "Ground truth" in the clinical sense (e.g., diagnosis from expert consensus or pathology) is not established or used as part of this 510(k) submission, as no human-in-the-loop or standalone AI performance study was conducted.

  4. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable, as there is no clinical test set to adjudicate.

  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 document is for a laser surgical instrument, not an AI-powered diagnostic device. No MRMC study was performed.

  6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This document is for a physical laser surgical instrument, not a standalone algorithm.

  7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable, as no clinical ground truth was established or used for performance evaluation in this 510(k) submission.

  8. The sample size for the training set: Not applicable. The device is a physical laser system, not an AI model that requires a training set.

  9. How the ground truth for the training set was established: Not applicable.

Summary from the document:

  • Clinical Studies: "No clinical studies were considered necessary and performed." (Page 9)
  • Proof of meeting acceptance criteria: The device demonstrates compliance with relevant international and national standards for electrical safety (ES60601-1), electromagnetic compatibility (IEC 60601-1-2), laser safety (IEC 60601-2-22, IEC 60825-1), and biocompatibility (ISO 10993 series). Software validation was also performed for the "MODERATE level of concern software." These non-clinical tests serve as the basis for demonstrating safety and performance.
  • Basis for Clearance: Substantial equivalence to a predicate device (OmniPulse Jr.™) by demonstrating that technological differences (pulse duration, aiming beam) do not raise new safety or effectiveness issues.

Dear Jake Yu:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
