Device Description Diode laser device consists of a main unit, a handheld, a foot switch and a power cord. Device composition and handle characteristics: The device includes a handle with a single-band 808nm semiconductor laser, and the semiconductor lasers of the handle are powered by the laser power supply in the host to emit the laser of the corresponding wavelength. Working principle of semiconductor laser: Semiconductor laser uses semiconductor materials of different doping types as laser working substance, uses natural cleavage surface to form resonant cavity for laser oscillation and amplification, and adds forward voltage to PN junction area of semiconductor laser to form particle number inversion of non-equilibrium carrier between conduction band and valence band of semiconductor substance. When a large number of electrons and holes in particle number inversion state are recombined, excess energy will be released, and these energies will be expressed in the form of photons, that is, laser is formed. Due to resonance amplification of cleavage surface resonant cavity, stimulated feedback is realized, so that laser can be directionally emitted and output from semiconductor laser. 7. Indication For Use Statement: Diode laser device is intended for hair removal, permanent hair reduction on all skin types (Fitzpatrick skin type I-VI), including tanned skin. Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months {6} 510(k) Summary after the completion of a treatment regime. ## 8.

Therefore, this difference will not affect the safety and effectiveness. ### Different2-Fluence The proposed device has different Fluence from the predicate device. For the difference on fluence between the predicate and proposed device, The Fluence of Predicate Device K232709 is 5-100J/cm2, while the propose device is 2-60 J/cm2. It is lower than 100 J/cm2, the safety of the product is no problem. However, the effectiveness cannot be determined, so we selected Reference Device K241642 with the same intended use for Fluence comparison, The Fluence of the Reference Device is 1-55.96J/cm2, which is similar to the Fluence of the proposed device, so the effectiveness of the product is not affected. And the proposed device has passed the IEC60601-1 test, IEC60601-1-2 test, IEC60601-2-22 test, IEC60825-1 test and performance test, the safety and performance of the product can be ensured. ### Different3/4- Dimension/ Weight The proposed device is different in dimension and weight from the predicate device. However, the dimension and weight difference are just in physical specification and this difference will not raise any issues in safety and effectiveness. By complying with AAMI/ANSI/ES 60601-1, the mechanical performance of the proposed device is determined to be accepted. Therefore, this difference will not affect safety and effectiveness of the proposed device. ## 9. Non-Clinical Test Conclusion Non clinical tests were conducted to verify that the proposed device met all design specifications as was Substantially Equivalent (SE) to the predicate device. The test results demonstrated that the proposed device complies with the following standards: - IEC 60601-1 Edition 3.2 2020-08, Medical electrical equipment - Part 1: General requirements for basic safety and essential performance - IEC 60825-1:2014, Safety of laser products - Part 1: Equipment classification, and requirements - IEC 60601-2-22: 2012 Medical electrical equipment - Part 2-22: Particular requirements for {8} 510(k) Summary basic safety and essential performance of surgical, cosmetic, therapeutic and diagnostic laser equipment - ISO 10993-10 Fourth edition 2021, Biological evaluation of medical devices - Part 10: Tests for skin sensitization - ISO 10993-23 First edition 2021-01, Biological evaluation of medical devices - Part 23: Tests for irritation - ISO 10993-5: 2009 Biological Evaluation of Medical Devices -- Part 5: Tests For In Vitro Cytotoxicity - IEC 60601-1-2 Edition 4.1 2020-09, Medical Electrical Equipment-Part 1-2: General Requirements For Basic Safety And Essential Performance - Collateral Standard: Electromagnetic Compatibility-Requirements And Test 10. Clinical Test Conclusion No clinical study is included in this submission. 11. Conclusion Based on the non-clinical tests performed, the subject device is as safe, as effective, and performance as well as the legally marketed predicate device, Diode laser therapy device leared under K232709. --- **Source:** [https://fda-staging.innolitics.com/device/K251801](https://fda-staging.innolitics.com/device/K251801) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
