Device Description
The PicoWay Laser System is a solid-state laser capable of delivering energy at wavelengths of 1064 nm, 532 nm, or 730 nm, at extremely short duration in the range of 240-500 (ps). The laser system contains one 755 nm (Alexandrite) laser head which is used to 'pump' (create) the 1064 / 532nm wavelengths. The outputs of the two lasers are optically combined on the laser rail so that their beam paths are identical as they exit the laser system. This allows the use of a single delivery system which can output either the 532nm or 1064nm wavelengths. The 532nm or 1064nm output energy is delivered to the skin through an Articulated Arm and Zoom Handpiece (HP) delivery system. There are also 3 hand pieces (Resolve), one for 1064nm and two for 532nm (low energy and high energy), which deliver a 10 x 10 array of focused spots to the skin and 1 Axicon hand piece (Resolve Fusion) for 532nm, which delivers a 10 x 10 array of focused and ring spots to the skin.

No

Explanation: The device is a laser system indicated for therapeutic purposes such as tattoo removal, benign pigmented lesion removal, treatment of acne scars, wrinkles, melasma, café au lait macules (CALMs), and lentigines. It does not perform any diagnostic functions.

No

The device description clearly describes a physical laser system with multiple hardware components (laser heads, articulated arm, handpieces). It is not solely software.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Function: The PicoWay Laser System is a laser system designed to deliver energy to the skin for therapeutic purposes, specifically tattoo removal and treatment of various skin conditions (pigmented lesions, acne scars, melasma, wrinkles).
  • Lack of Sample Analysis: The device does not analyze samples taken from the body. It directly interacts with the skin.
  • Intended Use: The stated intended uses are all related to treating conditions on the skin surface, not diagnosing conditions through laboratory analysis of biological samples.

Therefore, the PicoWay Laser System falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Performance Testing: Bench:
The performance testing of the subject PicoWay Laser System is based on the established testing previous cleared under PicoWay Laster System predicate (K191685). There are no changes in the design therefore the subject Picoway Laser System is based on the established performance testing of the device's predicate.

Performance Testing-Clinical:
A systematic literature search, using PubMed, Embase and Cochrane databases, was conducted to identify peer-reviewed articles published during January 1, 2015 to May 31, 2022 in which the PicoWay Laser System was used to treat benign pigmented lesions, with any of the PicoWay Laser Handpieces at 532 nm, 730 nm, 785 nm, and 1064 nm wavelengths. A supplemental search in ClinicalTrials.gov was performed using similar search terms to identify clinical trials with results relevant to the clinical safety and performance of the Picoway Laser System.
Nine articles were identified that reported on randomized controlled, or prospective, open label, evaluator-blinded clinical trials or retrospective evaluator-blinded studies that treated at least 10 individuals in each study using the PicoWay Laser System. The studies were conducted in the USA, the UK, Asia (Thailand, China) and the Middle East (Israel) and included a total of 262 subjects (228 females, 34 males; Fitzpatrick Skin Type (FST) I-V) treated for benign pigmented lesions, including nevus of Ota (n=20), café au lait macules (n=32), melasma (n=70) and lentigines (n=140), using the PicoWay Laser System. Melasma was treated with the PicoWay Zoom handpieces (532 nm and/or 1064 nm) and the PicoWay Resolve 1064 nm handpiece alone or combined with 12 weeks of daily application of 4% hydroquinone cream. CALMs were treated with the Zoom 532 nm handpiece; nevus of Ota was treated using the PicoWay Zoom 1064 nm handpiece, and lentigines were treated with the PicoWay 730 nm handpiece and the Zoom 532 nm handpiece.

Additionally, Candela identified an investigator-initiated prospective, open-label clinical study conducted by Principal Investigator Eric F. Bernstein, M.D. In this study, treatment of melasma with the PicoWay® device using the 1064nm Resolve handpiece resulted in statistically significant improvement (p=70 %) demonstrated improvement in the appearance of melasma at both follow-up visits. Investigator and Subject satisfaction ratings with treatment outcome were remarkably high (> 85%). Treatments were well tolerated, and there were no device-related adverse events.

9. Performance Data:

Performance Testing: Bench:

The performance testing of the subject PicoWay Laser System is based on the established testing previous cleared under PicoWay Laster System predicate (K191685). There are no changes in the design therefore the subject Picoway Laser System is based on the established performance testing of the device's predicate.

Performance Testing-Clinical

A systematic literature search, using PubMed, Embase and Cochrane databases, was conducted to identify peer-reviewed articles published during January 1, 2015 to May 31, 2022 in which the PicoWay Laser System was used to treat benign pigmented lesions, with any of the PicoWay Laser Handpieces at 532 nm, 730 nm, 785 nm, and 1064 nm wavelengths. A combination of MeSH terms and free-text searches for the device (picoway laser, picosecond laser) and for pigmented lesions and specific benign pigmented lesions nevus of Ota, CALM (macules) and/or melasma, were included in the search criteria. A supplemental search in ClinicalTrials.gov was performed using similar search terms to identify clinical trials with results relevant to the clinical safety and performance of the Picoway Laser System. The Literature Search methodology and findings are described in detail within the Clinical Literature Summary below.

Nine articles were identified that reported on randomized controlled, or prospective, open label, evaluator-blinded clinical trials or retrospective evaluatorblinded studies that treated at least 10 individuals in each study using the PicoWay Laser System. The studies were conducted in the USA, the UK, Asia (Thailand, China) and the Middle East (Israel) and included a total of 262 subjects (228 females, 34 males; Fitzpatrick Skin Type (FST) I-V) treated for benign pigmented lesions, including nevus of Ota (n=20), café au lait macules (n=32), melasma (n=70) and lentigines (n=140), using the PicoWay Laser System. Melasma was treated with the PicoWay Zoom handpieces (532 nm and/or 1064 nm) and the PicoWay Resolve 1064 nm handpiece alone or combined with 12 weeks of daily application of 4% hydroquinone cream. CALMs were treated with the Zoom 532 nm handpiece; nevus of Ota was treated using the PicoWay Zoom 1064 nm handpiece, and lentigines were treated with the PicoWay 730 nm handpiece and the Zoom 532 nm handpiece. The articles are identified in table 3 below.
