## Intended Use

The AuroLase System is intended for use in ablation, incision, excision, coagulation and vaporization of soft tissues in open and endoscopic surgical procedures.

## Device Story

AuroLase System is a portable, cart-based, liquid-cooled, dual-channel 810nm Class IV GaAs diode laser. It delivers 1-9W of continuous-wave near-infrared optical power via flexible optical fibers (Nanospectra Laser Delivery Device) to soft tissues. System includes an integrating sphere optometer for power calibration, a peristaltic pump for sterile saline coolant, ultrasonic flow sensors, and external thermocouple ports. Operated by healthcare professionals in clinical settings via a footswitch (tap-on/tap-off). Software monitors laser status, coolant flow, and system alerts. Laser energy induces photothermal ablation; liquid cooling moderates fiber surface temperature. Output allows for precise soft tissue management; benefits include controlled thermal effects during open or endoscopic procedures.

## Clinical Evidence

No clinical data. Substantial equivalence is supported by bench testing and verification/validation activities.

## Technological Characteristics

Dual-channel 810nm Class IV GaAs diode laser; 1-9W output per channel; 0.25W increments. Compatible with SMA-905 terminated fibers (≥600μm diameter, ≤0.37 NA). Integrated liquid cooling system (saline, 12 mL/min/channel). Includes integrating sphere optometer, ultrasonic flow sensors, and thermocouple ports. Cart-based form factor with medical-grade power supply. Software-controlled monitoring of laser status, coolant flow, and alerts. Sterilization/biocompatibility addressed via cleared LDD (K202953).

## Regulatory Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.

Dear Shepard Bentley:

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" (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 QS 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 (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-reporting-combination-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.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.

5. Device Description
The AuroLase® System (AS) is a portable, cart-based integrated liquid cooled laser system for use in professional healthcare facilities. The AuroLase System is used to generate photothermal ablation of selected soft tissues using 1-9W of near infrared optical power via 1 or 2 optical fibers either individually or simultaneously while providing liquid coolant to moderate the temperature at the fiber surface. The laser is delivered to the tissue of interest via an optical fiber system, the Nanospectra Laser Delivery Device (LDD), cleared via K202953. It is for prescription use only.

Central to the AuroLase System is the AuroLase Laser Device (ALD), a dual channel, continuous-wave, class IV GaAs diode laser (Figure 1 - red section) that provides the optical energy used to excite to soft tissues to ablative temperatures. The ALD incorporates an integrating sphere power meter (optometer) which is used to adjust the laser output that is delivered to the patient to the power shown on the display. Enabling the ALD's functionality is the AuroLase Control Unit (Figure 1 - green section) which incorporates: a) a peristaltic pump for providing sterile coolant to the Laser Delivery Devices, b) dual ultrasonic sensors to assure that coolant flows through the LDDs, c) a footswitch to control laser activation, d) temperature monitors for up to two optional external thermocouples, and e) a software application that controls, integrates, and monitors these functions. A medical-grade power supply is near the base of the unit to provide electrical service to the rest of the system as well as mechanical stability.

The AS is designed and tested for operation in a professional healthcare facility.
