## Intended Use / Indications for Use:

The PicoWay Laser System is indicated for the following at the specified wavelength:

## 532nm

Removal of tattoos for Fitzpatrick skin types I-III to treat the following tattoo colors: red, yellow and orange.

## 1064nm

Removal of tattoos for all skin types (Fitzpatrick I-VI) to treat the following tattoo colors: black, brown, green, blue and purple.

## Description:

The PicoWay Laser System is a solid state laser capable of delivering energy at waveleneths of 1064 nm or 532 nm at short durations of 240-750 picoseconds (ps) at repetition rates up to 5 Hz. The device system is comprised of a system console, an articulated arm, and an attached

{4}------------------------------------------------

handpiece. The laser output at each wavelength is generated within the laser chassis and delivered to the skin through an articulated arm delivery system terminated by a zoom handpiece (HP). The light-weight and ergonomic zoom handpiece allows the spot size on the skin to be easily adjusted from 3 mm to 6 mm in steps of 1 mm. The system includes an internal calibration port with an internal meter located on the control panel of the system console, which is used to verify the transmission of the laser beam into the articulated arm. The PicoWay system control panel enables the user to select the desired energy density (fluence) level and repetition rate. The control panel is also used to obtain feedback from the system, such as the number of pulses delivered or spot size selected.

#### Technological Characteristics:

The PicoWay Laser System has the same intended use and similar indications for use, technological characteristics, and operating principles as the Cynosure PicoSure™ workstation (K121346) and the Medlite C6 Q-Switched Nd:YAG Laser (K014234). The PicoWay device design and components are very similar to those of the predicate devices. For each of these device systems, the treatment handpiece is attached to an articulating arm that is connected to the main system console. For each system, the user interface is located at the front/top of the console. For the PicoWay and predicate devices, the laser output at each wavelength is generated within the laser chassis and delivered to the skin through an articulated arm delivery system with a handpiece attached to the end. The handpiece allows the spot size on the skin to be adjusted according to device specifications. Each system thus consists of the articulating arm (and attached handpiece), as well as an electrically powered system console that houses the software, user interface, and produces the laser energy. All three of the devices include an aiming beam feature that assists the user in delivering the treatment beams, but does not deliver any therapeutic energy. The PicoWay provides similar key design aspects, including similar spot sizes, laser wavelengths, pulse width, and laser types, as its predicate devices. The frequency (repetition rate) of the PicoWay System is within the frequency range of the predicates. Further, each of the devices presents a range of spot sizes to allow the user to choose the most appropriate spot size for each patient. Differences in the specific maximum energy levels and fluence delivered with the PicoWay and the predicate devices do not raise any new types of safety or effectiveness questions because the PicoWay parameters are within the range of maximums of the predicate devices. Further, PicoWay performance and safety were evaluated and demonstrated in the clinical study.

#### Performance Data:

Electrical safety and electromagnetic compatibility (EMC) testing for the PicoWay Laser System was conducted by an independent test laboratory in accordance with IEC 60601-1, Medical electrical equipment. Part 1: General requirements for basic safety and essential performance. The PicoWay System was determined to be in conformance with applicable IEC standards (IEC 62366, 60601-1, 60601-1-6, IEC 60601-2-22, and IEC 60825-1).

The biocompatibility of the PicoWay device is also based on the established biocompatibility of previously cleared devices, and on biocompatibility evaluations consistent with the guidelines in

{5}------------------------------------------------

FDA's "Use of International Standard ISO-10993. 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing'" Guidance Document.

Software verification and validation testing was conducted and documentation was provided as recommended by FDA's "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." Device software verification and validation results demonstrated that testing results were found acceptable for software release.

All performance testing demonstrated that the PicoWay Laser System performs according to specifications and functions as intended.

#### Clinical Data:

A single arm, prospective, self-controlled multicenter study was conducted to evaluate the safety and effectiveness of the PicoWay System. The clinical evaluation of 60 subjects (75 tattoos) at 3 investigational sites in the U.S. demonstrated that the PicoWay performs as intended and presents a favorable safety profile for its indicated use. The majority of subjects were female, Caucasian, with a mean age of 34 years.

Each subject was assessed at baseline, post-treatment, and during follow up after final treatment. The tattoos were photographed before treatment, immediately after treatment, as well as during follow up visits after treatment end. For the primary endpoint analysis, the subjects' tattoos were evaluated by three blinded independent evaluators. In addition, investigator and subject assessments were also captured as part of the study. Any potential safety effects were noted immediately after each laser treatment and before each treatment.

The primary effectiveness endpoint of the study was met if the global percent tattoo clearance reaches at least 50% clearance (score ≥3) post 3, 6, or 9 treatments or at 3 months post the final treatment, as agreed by at least 2 of the 3 evaluators. Eighty-six percent (86%) of the treated tattoos achieved at least 50% clearance after 3 treatments. Therefore, the primary effectiveness endpoint was achieved. Additional efficacy analyses per investigator and subject assessments further confirm device performance.

The safety of the PicoWay System was evaluated based on the rate of occurrence and severity of adverse events reported during the study. A low rate of adverse events was reported throughout the study, with only 9 subjects with any device related adverse events of the 391 treatments performed. There were no serious adverse events in the study and no subjects discontinued from the study due to adverse events. Further, the occurrence and severity of adverse events did not increase with additional treatments performed. None or mild responses were observed for nearly all of the treatment-associated responses immediately after treatment and during follow up. Study results also indicated a consistent trend of low levels of pain/discomfort.

Based on the clinical performance as documented in the pivotal clinical study, the PicoWav System was found to have a safety and effectiveness profile that is similar to the predicate device.

{6}------------------------------------------------

#### Summary of Substantial Equivalence:

The PicoWay and the predicate devices have the same intended use as laser systems used for tattoo removal with similar indications for use. The PicoWay Laser System presents similar technological characteristics as its predicate devices, including the laser type, wavelengths, device design, pulse width, frequency, spot sizes and system components. Although there are some differences between the PicoWay and its predicates in terms of the maximum pulse energy and fluence, these differences do not present any new types of safety or effectiveness questions since the PicoWay parameters are within the range reported for marketed tattoo removal laser systems. Further, PicoWay performance has been demonstrated in a clinical investigation of 60 subjects with 75 tattoos, and results confirm the safety and effectiveness profile of the device. The PicoWay device and its predicates all operate with the same mechanism of action based on selective photothermolysis of tattoo pigment particles using laser energy. Therefore, the PicoWay has the same intended use and similar indications for use, technological characteristics, and principles of operation as the predicate devices. The PicoWay is substantially equivalent to the predicate devices.

#### Conclusions:

Clinical testing of the PicoWay device demonstrated that the device performs as intended with a favorable safety profile. Results in the study were comparable to those reported for the predicate device, in support of substantial equivalence. The non-clinical data further support the safety of the device, and software verification and validation testing demonstrates that the PicoWay device is expected to perform as intended in the specified use conditions. The PicoWay System is substantially equivalent to the predicate devices.
