Intended Use

The Candela GentleLase GL Dermatology Laser is indicated for the following uses: the Photocoagulation of Dermatological vascular lesions. the removal of hair.

Device Story

Candela GentleLase GL is a long-pulse Alexandrite laser system emitting 755 nm near-infrared energy. Device components include high-voltage power supply, modulator, optical laser head, circulator system, optical fiber/handpiece delivery system, software control system, and Dynamic Cooling Device (DCD). Operated by clinicians in a medical setting, the system uses an onboard control panel for treatment parameter selection. The DCD cools skin prior to laser pulses to minimize thermal damage and reduce pain. Laser energy is delivered to targeted vascular lesions or hair follicles. Safety interlocks protect patients and operators. Clinical benefit includes effective hair removal and vascular lesion treatment with managed thermal safety.

Clinical Evidence

Clinical trial conducted to evaluate hair removal efficacy and safety. Results demonstrated that the system removes unwanted hair without raising unexpected safety issues.

Technological Characteristics

Alexandrite crystal laser source; 755 nm wavelength; pulsed energy delivery; optical fiber/handpiece delivery system; integrated Dynamic Cooling Device; onboard software control system; safety interlock systems.

Indications for Use

Indicated for photocoagulation of dermatological vascular lesions and hair removal in patients requiring dermatological laser treatment.

Regulatory Classification

Identification

#### Description:

The Candela (Modified) GentleLase GL Laser utilizes an Alexandrite rod (crystal) which emits pulsed energy at 755 nanometers in the near infrared region. Energy from the laser is directed to the targeted area via an optical fiber/handpiece delivery system. The Dynamic Cooling Device functions to cool the skin prior to laser treatment, minimizing thermal damage to skin during laser treatment and reducing pain associated with laser treatment. The Candela GentleLase Lasers are designed with six major components:

- 1. High voltage power supply and modulator system
- Optical laser head 2.
- 3. Circulator system
- Optical delivery system 4.
- న్న Software control system
- 6. Dynamic cooling device

The Candela GentleLase Lasers are equipped with safety interlock systems to protect patients and operators. Users of the device make selections from an onboard control panel to regulate operation during treatment.

The intended use of the laser system is for the Photocoagulation of Dermatological vascular lesions and for hair removal.

#### Testing:

A clinical trial demonstrated that the GentleLase Laser System removes unwanted hair without raising any unexpected safety issues.

# Summary of Substantial Equivalence:

The Candela GentleLase Lasers have the same intended use, utilize the same operating principles and match key design aspects, including similar spotsize, the same wavelength and the same maximum delivered power as the predicate devices.

On the basis of similarities in methods of assembly, method of operation, intended uses, and clinical data Candela believes that its Candela GentleLase Laser System is substantially equivalent to the predicate devices.

# Dear Mr. Caplan:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
