Not Found

AI/ML (Artificial Intelligence / Machine Learning)

No
The summary describes a standard CO2 laser system for tissue treatment and does not mention any AI/ML components or functionalities.

Therapeutic

Yes
The device is described as being used for "vaporization, coagulation in dermatology and plastic surgery, general surgery, gynecology, podiatry, dental and otorhinolaryngology" which indicates it is used for treatment.

Diagnostic

No
Explanation: The device is described as a "Dermatological Carbon Dioxide Laser System" used for "human tissue vaporization, coagulation" in various surgical fields. Its function is to perform medical procedures, not to diagnose conditions.

SaMD (Software as a Medical Device)

No

The device description explicitly states it is a "Dermatological Carbon Dioxide Laser System" and describes its physical properties (wavelength, energy density, divergence angle), indicating it is a hardware device that uses laser technology. The performance studies also mention compliance with hardware-related standards (IEC 60601-1, IEC 60601-2-22, IEC 60825-1).

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

• Intended Use: The intended use clearly states that the device is used for human tissue vaporization and coagulation in various surgical and medical specialties. This is a direct treatment or surgical procedure performed on a living patient.
• Device Description: The description details a laser system that uses a focused light beam to interact with human tissue. This is a physical intervention, not a diagnostic test performed on samples outside the body.
• Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.) or providing diagnostic information based on such analysis. IVDs are designed to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.

Therefore, this device falls under the category of a therapeutic or surgical device, not an In Vitro Diagnostic.

Dear Ray Wang:

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.
