The 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 after the completion of a treatment regime.
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.
This 510(k) clearance letter and summary primarily focus on demonstrating substantial equivalence to a predicate device, which is typical for Class II medical devices. The information provided does not contain a detailed study report with specific acceptance criteria related to a performance study for the device's efficacy (hair removal/reduction). Instead, it relies on comparison to a predicate device and adherence to recognized standards for safety and performance.
Here's an analysis based on the provided text:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly state "acceptance criteria" in the context of a clinical or performance study with numerical targets for efficacy (e.g., a certain percentage of hair reduction). Instead, it relies on demonstrating substantial equivalence to a predicate device that is already legally marketed for the same indication. The "performance" assessment is based on the similarity of technical specifications and the successful completion of non-clinical tests to applicable standards, ensuring safety and basic functionality.
| Item | Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|---|
| Clinical Efficacy | Substantially equivalent indications for use as predicate (hair removal, permanent hair reduction on all skin types (Fitzpatrick skin type I-VI), including tanned skin, with permanent hair reduction defined as a long-term, stable reduction at 6, 9, and 12 months post-treatment.) | The proposed device has the same Indications for Use as the predicate devices, K232709 and K241642. The document states that the safety of the product is no problem despite fluence differences, and effectiveness is considered similar to a reference device with comparable fluence. No direct performance data is provided in terms of hair reduction percentage or success rates from a clinical trial in this document. |
| Technical Design | Laser Type, Classification, Wavelength, Frequency, Pulse Duration, Power Supply, Dimensions, Weight to be comparable or justified if different. | - Laser Type, Classification, Wavelength, Frequency, Pulse Duration, Power Supply: Marked as "SAME" as the predicate. - Spot Size: Different, but argued not to affect safety and effectiveness, only treatment area. - Fluence: Different from the primary predicate but similar to a reference device (K241642), ensuring effectiveness is "not affected." Safety argued to be no problem due to lower max fluence than the predicate. - Dimension/Weight: Different but argued not to affect safety/effectiveness and comply with mechanical performance standards. |
| Safety Testing | Compliance with recognized safety standards. | The device passed non-clinical tests verifying compliance with IEC 60601-1, IEC 60825-1, IEC 60601-2-22, ISO 10993-10, ISO 10993-23, ISO 10993-5, and IEC 60601-1-2. These standards cover general safety, laser safety, specific laser equipment safety, biocompatibility (skin sensitization, irritation, cytotoxicity), and electromagnetic compatibility. |
2. Sample size used for the test set and the data provenance
The document explicitly states: "No clinical study is included in this submission."
Therefore:
- Sample size for the test set: Not applicable (no clinical test set was used for this submission).
- Data provenance: Not applicable.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable, as no clinical study or test set with expert-established ground truth was part of this submission. The "ground truth" for clearance in this context is established by the FDA's acceptance of substantial equivalence to an already cleared device, which presumably had clinical data at the time of its own clearance.
4. Adjudication method for the test set
Not applicable, as no clinical test set requiring adjudication was used.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This device is a laser for hair removal, not an AI-assisted diagnostic or imaging device that would typically involve human readers or MRMC studies.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical medical device (diode laser), not a software algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For the purpose of this 510(k) submission, the "ground truth" for the device's indications for use and general safety/effectiveness is implicitly the regulatory clearance and established performance of the predicate devices. The applicant is demonstrating that their device is sufficiently similar to these predicates to be considered equally safe and effective.
8. The sample size for the training set
Not applicable, as no clinical study was conducted. There is no "training set" in the context of this 510(k) submission for efficacy.
9. How the ground truth for the training set was established
Not applicable, as no clinical study or training set was used.

Analysis
Different1-Spot Size
The proposed device is different in Spot Size from the predicate, Spot size only affects the area of treatment, not affect the therapeutic effect. 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.
- 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
