The control panel is in the form of an LCD touch screen in front of device and displays for operating and monitoring the laser. The system can automatically identify different handpieces. The product includes 2 types of handpieces that are in the same spot size and 2 combinations of wavelengths. The diode is exited to emit a high-power therapeutic laser beam intended to reduce unwanted body hair (e.g., armpit, leg, arm, back, chest and bikini line). It is intended to be used by a trained professional to emit a laser of wavelength around 810 nm or 755+810+1064 nm, delivered by a dedicated handpiece, to destroy hair follicles by heat. #### INDICATIONS FOR USE V. The Diode Laser System includes 2 types of handpieces with same 1.2 x 1.4 cm spot size: Single-Wavelength Handpiece 810 nm wavelength The 810 nm wavelength handpiece is intended for permanent reduction in hair regrowth defined as a long term, stable reduction in the number of hairs re-growing when measured at 6, 9 and 12 months after the completion of a treatment regimen. Use on all skin types (Fitzpatrick I-VI), including tanned skin.(HR. and FHR Modes) #### Trio-Wavelength Handpiece The Trio-Wavelength Handpiece combines 3 wavelengths (755+810+1064 nm) into a single handpiece.

PERFORMANCE DATA The Diode Laser System has been determined through engineering testing to verify laser energy output and electrical safety. ## Electrical safety and electromagnetic compatibility The test results demonstrated that the proposed device complies with the following standards: IEC 60601-1: 2005+corr.1:2006+Corr.2.2007+A1:2012 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance {10}------------------------------------------------ Image /page/10/Picture/1 description: The image contains a logo for a company called "Smedtrum Medical Technology Co., Ltd." The logo consists of a geometric shape on the left, resembling an abstract letter "S" in shades of teal. To the right of the shape is the company name in both Chinese and English. The Chinese characters are at the top, and the English name "Smedtrum" is in a larger font size, with "MEDICAL TECHNOLOGY CO., LTD." below it in smaller letters. IEC 60601-1-2:2020 Medical electrical equipment -Part 1-2: General requirements for basic safety and essential performance-Collateral Standard: Electromagnetic disturbances - Requirements and tests IEC 60825-1:2014 Safety of Laser products-Part 1: Equipment classification and requirements IEC 60601-2-22:2019 Medical electrical equipment - Part 2-22: Particular requirements for basic safety and essential performance of surgical, cosmetic, therapeutic and diagnostic laser equipment ## Software Verification and Validation Testing Software verification and validation testing were conducted, and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern since a failure of the software could result in minor injury to a patient or to a user of the device. ## Sterilization and Shelf-Life The proposed device is not provided sterile and does not need to be sterilized. The handpiece and the body are cleaned with a soft cloth moistened with ethanol of 70% strength or higher. The proposed device is reusable and does not have a restricted shelflife. ## Biocompatibility The handpiece sapphire tip may be contact with the intact skin of patients. According to FDA guidance document "Use of International Standard ISO 10993-1, " Biological evaluation of medical device - Part 1: Evaluation and testing within a risk management process "" three biological effects were determined in following three test: Cytotoxicity, Sensitization and Irritation. In Cytotoxicity test, L-929 cell cultured in 96-well plates were treated with extract of test article (100%, 75%, 50%, and 5% in MEM medium) and then incubated at 37°C in cell incubator of 5% Diode for 24h. Viability % of the 100% extract of stainless steel and aluminum alloy is 83.2% and 87.9%. respectively, so the extract of test article passed test requirement and did not show potential cytotoxicity to mouse fibroblast L-929 cells. In Skin sensitization test. Guinea Pig Maximization Test (GPMT) were performed for determination of the skin sensitizing potential of test article extraction. Under {11}------------------------------------------------ 巨興醫學科技股份有限公司 Smedtrum MEDICAL TECHNOLOGY CO.,LTD. GPMT method, the results shows the test article did not cause delayed dermal contact sensitization in the guinea pig. In Skin irritation test, the extraction solution of the test article (extraction in 0.9% sodium chloride injection and sesame oil) and control solution were treated on the backs of fur clipped rabbits. The appearance of each application site was recorded and scored after 1 hour, 24 hours and 72 hours treatment. The score of skin reaction of test extraction at different time point were 0 as negative control group and showed no potential skin irritation risk. Three biological effects, cytotoxicity, sensitization and irritation testing, were performed and test results did not identify any biological response or risk. The Diode Laser System meets the ISO 10993-1 standard requirements for biocompatibility and no further characterization testing is required. #### Bench testing Bench testing was conducted to validate that the energy output parameters of the subject device are similar to those of the predicate device. ### VIII. CONCLUSION The Diode Laser System has the same intended use, similar indications for use, the same technological characteristics, the same energy used, and the same operating principles as its predicates. The non-clinical data and performance testing reports in this submission demonstrate that Diode Laser System meets the expected performance requirements. Any difference between the subject and predicate device do not raise new issues of safety or effectiveness. Based on above analysis, the Diode Laser System is as safe, as effective, and performs as well as the cited predicate device.
