The summary describes a laser system with menu-driven controls for selecting pulse energy and frequency. There is no mention of AI, ML, image processing, or any other technology that would suggest the use of AI/ML. The performance studies focus on bench tests, software validation (moderate level of concern), and biocompatibility, none of which indicate AI/ML components.
Yes
The device is used for various medical and surgical procedures across multiple specialties, including incision, resection, ablation, coagulation, hemostasis, and vaporization of tissues, which directly aim to treat or improve health conditions.
No
The Holinwon 30 laser system is indicated for surgical procedures involving incision, resection, ablation, coagulation, hemostasis, and vaporization, which are therapeutic actions, not diagnostic ones.
No
The device description clearly states it is a "pulsed solid-state Holmium:YAG laser system," which is a hardware device that delivers laser energy. The software mentioned is for controlling the hardware's parameters.
Based on the provided information, the Holinwon 30 laser system is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly describes surgical procedures performed directly on the patient's body (in vivo). It involves superficial incision, resection, ablation, coagulation, hemostasis, and vaporization of various tissues.
- Device Description: The device is a laser system designed to deliver energy for these surgical procedures.
- Lack of In Vitro Activities: There is no mention of the device being used to examine specimens (like blood, tissue, or urine) outside of the body to provide information for diagnosis, monitoring, or treatment.
IVD devices are specifically designed for testing samples taken from the human body. The Holinwon 30 is a surgical tool used directly on the patient.

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal
1
statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
