Intended Use

10THERMA indicated for use in dermatologic and general surgical procedures for electrocoagulation and hemostasis.

Device Story

10THERMA is a high-frequency electrosurgical unit (ESU) used in dermatologic and general surgical procedures. The device generates high-frequency current (6.78 MHz) in a main console, which is delivered to the patient's skin via a monopolar electrode handpiece. Electrical resistance in the skin converts this energy into heat, facilitating tissue coagulation and hemostasis. The system includes a main body with a touchscreen interface, handpiece, return pad, coupling fluid, and cooling gas (cryogen) to manage thermal effects. It is operated by a clinician via manual controls or a footswitch. The device provides thermal coagulation to achieve hemostasis, benefiting patients by enabling controlled surgical tissue management.

Clinical Evidence

Bench testing only. No clinical studies were performed. Safety and performance were validated through electrical safety (IEC 60601 series), software validation (IEC 62304), biocompatibility (ISO 10993 series), and risk management (ISO 14971) testing.

Technological Characteristics

High-frequency electrosurgical unit; 6.78 MHz output frequency; 400 W maximum power; monopolar electrode configuration. Components include main console with LCD touchscreen, handpiece, return pad, coupling fluid, and cryogen cooling. Software classified as Moderate level of concern. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-2-2, IEC 62366-1, and ISO 10993 standards.

Dear Do Kim:

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 (the 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 available 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

{1}------------------------------------------------

(https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the OS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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 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 Part 803) for devices or postmarketing safety reporting (21 CFR Part 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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
