AI/ML (Artificial Intelligence / Machine Learning)

No
The summary describes a standard diode laser system for hair removal and does not mention any AI or ML components or functionalities. The description of components is purely hardware-based.

Therapeutic

No
The device is described as a "surgical device" intended for "hair removal" and "permanent hair reduction," which are aesthetic procedures, not explicitly therapeutic in nature based on the provided text.

Diagnostic

No
The device is described as a surgical device intended for hair removal and permanent hair reduction, not for diagnosing any medical condition.

SaMD (Software as a Medical Device)

No

The device description explicitly lists hardware components such as a Handpiece, Touchscreen, Emergency Switch, Key Switch, Connector, Indicator Lamp, and Foot Switch, indicating it is a physical device, not software-only.

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

• Intended Use: The intended use is for hair removal and permanent hair reduction. This is a therapeutic/cosmetic procedure performed directly on the patient's body.
• Device Description: The device is described as a "surgical device" and its components are related to delivering laser energy to the skin.
• Mechanism of Action: While not explicitly detailed, the mechanism of action for a diode laser in this context involves using light energy to target hair follicles within the body.
• Lack of IVD Characteristics: There is no mention of analyzing samples (blood, tissue, etc.) in vitro (outside the body) to diagnose a condition, monitor a treatment, or screen for a disease.

IVD devices are used to examine specimens obtained from the human body to provide information for diagnostic purposes. This device operates directly on the patient's body for a non-diagnostic purpose.

Analysis 1

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 substantially equivalency.

Analysis 2/3

The proposed device is different in dimension and weight from the proposed device is a trolley type, while the predicate device is a desktop type. By complying with IEC 60601-1, the mechanical performance of the proposed device is determined to be accepted, therefore, this difference will not affect the substantially equivalency.

Analysis 4

The proposed device is different in patient-contacting materials. But all patient-contacting materials used in proposed device has been evaluated as ISO 10993-1, as the results of evaluation, there is no biocompatibility concerns raised from the patient-contacting materials used in proposed device, so this different will not affect the substantially equivalency.
