Intended Use

The Candela Family of Q-Switched Alexandrite Lasers are indicated for treatment in the following uses: Pigmented Lesions Tattoos

Device Story

The Candela Q-Switched Alexandrite Laser is a medical laser system used in dermatology and plastic surgery. It utilizes an Alexandrite rod as the solid-state laser medium, excited by xenon flashlamps, to deliver 755 nm wavelength energy. The system features a microprocessor-based controller that monitors system functions, including energy density (fluence) and repetition rate. Users operate the device via electronic controls and a display panel, selecting parameters and monitoring pulse delivery. Energy is delivered through a lens-coupled, user-replaceable optical fiber and handpiece. A calibration port with an internal meter verifies optical fiber transmission and handpiece output. The device is used by clinicians to treat pigmented lesions and tattoos. By delivering controlled laser pulses, the device enables targeted tissue treatment, potentially benefiting patients through the removal or reduction of pigmented skin conditions and tattoos.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological characteristics and design similarities to legally marketed predicate devices.

Technological Characteristics

Solid-state Alexandrite laser; 755 nm wavelength; pulse duration 50-120 microseconds (or 0.050-0.120 ms when Q-switching disabled). Features: Pockels cell, xenon flashlamps, deionized water cooling system, microprocessor-based controller. Supports 2mm, 3mm, and 5mm spot sizes. Delivery via lens-coupled optical fiber and handpiece. Class II device.

Indications for Use

Indicated for the treatment of pigmented lesions and tattoos in patients requiring laser surgical intervention.

# Device Description

The Candela Q-Switched Alexandrite Laser consists of an Alexandrite laser head, power supply and deionized water circulator The laser head contains cavity mirrors, pockels cell, solid state laser medium (the Alexandrite rod), and two high intensity xenon flashlamps which excite the laser medium. A calibration port with an internal meter is located on the control panel, which is used to verify the transmission of the optical fiber and handpiece, and to calibrate the output of the handpiece at selected fluence levels. The temperature of the laser head is regulated by the circulation of distilled water at a controlled temperature.

The Candela Q-Switched Alexandrite Laser delivers laser energy at a wavelength of 755 nm and pulse duration between 50 and 120 microseconds. When the Q-switching mechanism is disabled the system has the capability of producing a laser pulse duration of 0.050 - 0.120 milliseconds. The output of this laser is delivered to the area of treatment by means of a lens coupled user replaceable optical fiber with a treatment

handpiece attached to its distal end. A trigger switch is used to control the delivery of pulses.

A microprocessor based system controller is used to monitor and direct all system functions. Users of the laser select parameters such as desired energy density (fluence) level and repetition rate and monitor operation via electronic controls and a display panel. The control panel is also used to enable or disable the triggering of the laser, to initiate the calibration feature and to obtain feedback from the system, such as the number of pulses delivered or spot size selected. The Candela Q-Switched Alexandrite Laser supports 2mm, 3mm, and 5mm nominal spot sizes.

#### Description of Intended Use

The Candela Family of Q-Switched Alexandrite Lasers are indicated for treatment in the following uses:

Pigmented Lesions Tattoos

#### Rationale for Substantial Equivalence

The Candela Q-Switched Alexandrite Laser has the same intended use, utilizes similar functional features (including power output, spot size, repetition rate, energy, and fluence) and matches key design aspects (including wavelength, light generation medium, power supply, cooling and controls system) , as the predicate devices.

The Candela Q-Switched Alexandrite Laser shares similar methods of assembly, method of operation, and intended uses, and therefore is substantially equivalent to the current legally marketed Candela Q-Switched Alexandrite Laser K073534, Candela 3630 Laser Systems, Alexandrite, K063074 and Cynosure Apogee Elite Laser, Alexandrite, K034030 predicate devices.

# Safety and Effectiveness Information

Candela believes that there are no new questions of safety or effectiveness raised and the Candela Q-Switched Alexandrite Laser is substantially equivalent to the current legally marketed Candela Q-Switched Alexandrite Laser, K073534, Candela 3630 Laser System (Alexandrite) K063074, and Cynosure Apogee Elite Laser (Alexandrite) K034030 predicate devices in intended use and technological features and therefore the risks and benefits are comparable to the predicate devices.

#### Conclusion

Based on the similarities in indications for use, design features, and functional features, the Candela Q-Switched Alexandrite Laser has been shown to be substantially equivalent to the current legally marketed predicate devices.
