Intended Use
The Photosilk and Photosilk Plus systems are indicated for permanent hair reduction, and the treatment of benign vascular and pigmented lesions. The Photosilk and Photosilk Plus pulsed light system is indicated for permanent hair reduction. It is also indicated for photocoagulation of dermatological vascular lesions and leg veins, indicated for photocoagulation of and the treatment of benign pigmented lesions. The integrated cooling handpiece is intended to provide pre-cooling of the epidermis, to reduce thermal effects and discomfort associated with light applications.
Device Description
Photosilk and Photosilk Plus are intense pulsed light systems, having a Xenon flashlamp located in the handpieces. It is a light source with a wavelength range of approximately 400 - 1200nm. Light emission activation is by foot switch. Overall weight of the laser is 65 Kg, and the size is 103x50x48 cm (HxWxD). Electrical requirement is 220 VAC, 15A, 50-60 Hz, single phase. Skin cooling is provided by the integrated cooling handpiece that contains cooled water circulated through the handpiece body, the face of which is in contact with the skin.

No
The description focuses on the physical characteristics and light-based technology of the device, with no mention of AI or ML.

Yes
The "Intended Use / Indications for Use" section states the device is indicated for permanent hair reduction, and the treatment of benign vascular and pigmented lesions, which are medical treatments.

No
The device descriptions indicate that the Photosilk and Photosilk Plus systems are used for treatment purposes (permanent hair reduction, photocoagulation, treatment of lesions), not for diagnosing conditions.

No

The device description clearly outlines hardware components such as a Xenon flashlamp, handpieces, a foot switch, and a cooling system, indicating it is a physical device, not software-only.

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

Here's why:

  • Intended Use: The intended use clearly states that the Photosilk and Photosilk Plus systems are for permanent hair reduction and the treatment of benign vascular and pigmented lesions. These are all procedures performed directly on the patient's body for therapeutic or cosmetic purposes.
  • Device Description: The description details an intense pulsed light system that emits light onto the skin. This is a physical treatment method, not a diagnostic test performed on biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (like blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's health status.

IVD devices are designed to be used in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The Photosilk and Photosilk Plus systems operate in vivo (on the body) for treatment.
