System, K942152 | | | Candela Q-Switched Alexandrite Laser (AlexLAZR), K955662 | #### Device Description The Candela Family of Q-Switched Alexandrite Laser (AlexLAZR) systems: 532 Nd:YAG Handpiece Accessory consists of a cylindrical housing connecting to the distal end of the optical fiber which plugs into the standard Candela Family of Q-Switched Alexandrite Laser (AlexLaze) systems. The fiber carries the 755nm light from the Candela Family of Q-Switched Alexandrite Laser (AlexLAZR) systems to the handpiece at the distal end where the wavelength conversion from 755mm to 532nm occurs. The principle of operation is outlined here. The 755nm light is focused by focusing lenses to a 2mm beam waist within an Nd: YAG rod situated in the heart of the converter module. It is known that Nd: Y AG can be pumped at 755nm and made to lase at 1064nm with high efficiency. The Nd: YAG rod has two appropriately coated mirrors, one on either side, to form a laser resonator. Within the laser resonator is a Brewster Plate which {1}------------------------------------------------ ensures that the output 1064nm beam is polarized (in another variation of the same scheme, the Nd:YAG will be replaced by Nd:YVO4 or similar gain medium which provides a naturally polarized output, eliminating the need for a Brewster Plate). The output of the Nd: YAG laser has the same pulse duration as the original 755nm laser, but the wavelength is now 1064mm. The 1064nm beam is then incident on a KTP crystal that is aligned for optimum phase matching for second harmonic generation at 1064mm. The KTP crystal converts 1064mm to 532nm efficiently. A dichroic beam-splitter separates the 532nm beam from the residual unconverted 1064m. The 532nm beam is appropriately shaped and sized using lenses and is incident on the skin during treatment. The unconverted 1064nm that is rejected by the beam-splitter is safely absorbed in a beam dump within the module. The Candela Family of Q-Switched Alexandrite Laser (AlexLAZR) systems: 1064 Nd: YAG Handpiece Accessory is very similar to the 532nm handpiece except that there is no KTP crystal for the 1064nm to 532nm conversion. The beam is extracted immediately after the Nd: Y AG laser resonator. #### Description of Intended Use The Candela Family of Q-Switched Alexandrite Laser (AlexLAZR) Systems: 532 and 1064 Nd: YAG Handpiece Accessories are indicated for the following uses: Tattoo Removal Treatment of Vascular Lesions Treatment of Pigmented Lesions Incision, Excision, Ablation, Vaporization of Soft Tissue for General Dermatology #### Rationale for Substantial Equivalence The Candela Family of Q-Switched Alexandrite Laser (AlexLAZR) Systems: 532 and 1064 Nd: YAG Handpiece Accessories have the same intended use and 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 Family of Q-Switched Alexandrite Laser (AlexLAZR) Systems: 532 and 1064 Nd: YAG Handpiece Accessories shares similar methods of assembly, method of operation and intended uses, and therefore is substantially equivalent to the currently legally marketed Hoya ConBio Inc., Medlite C3 Q-Switched Nd:YAG Laser, K011677, Candela Q-Switched, Frequency Doubled, Nd: YAG Laser System, K942152, and Candela Q-Switched Alexandrite Laser (AlexLAZR), K955662. #### Safety and Effectiveness Information The Candela Family of Q-Switched Alexandrite Laser (AlexLAZR) Systems: 532 and 1064 Nd: Y AG Handpiece Accessories are substantial equivalent to the currently legally marketed Hoya ConBio Inc., Medlite C3 Q-Switched Nd: YAG Laser, K011677, Candela O-Switched, Frequency Doubled, Nd: YAG Laser System. K942152, and Candela O-Switched Alexandrite Laser (AlexLAZR), K955662 predicate devices in intended use and technological features and therefore the risks and benefits are comparable to the predicate devices. {2}------------------------------------------------ We therefore believe that there are no new questions of safety or effectiveness raised by the introduction of Candela Family of Q-Switched Alexandrite Laser (AlexLAZR) Systems: 532 and 1064 Nd: YAG Handpiece Accessories. ## Conclusion Base on the similarities in indications for use, design features, and functional features Candela Family of Q-Switched Alexandrite Laser (Alex147R) Systems: 532 and 1064 Nd: YAG Handpiece Accessories have been shown to be substantially equivalent to the current legally marketed predicate devices. 3 {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.

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 (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. 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); good manufacturing practice requirements as set {4}------------------------------------------------ Page 2 - Mr. Jeffrey Roberts forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 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. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
