Yes
The device is an accessory to laser tattoo removal procedures, which are considered therapeutic. It directly modifies the biological response (dissipating laser-induced whitening and gas bubbles) to allow for more aggressive and effective treatment of a medical condition (tattoos).
No
The device is described as an accessory to laser tattoo removal procedures, designed to allow multiple laser passes in a single session by dissipating laser-induced whitening. It does not perform any diagnostic function such as detecting, examining, or monitoring a disease or condition.
No
The device description explicitly states that the Soliton Acoustic Wave Device (AWD) is composed of three physical parts: the Console, the Hand Piece, and the connecting Cable. These are hardware components, not software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens from the human body. The Soliton Acoustic Wave Device (AWD) is applied directly to the skin surface to assist in a tattoo removal procedure. It does not analyze blood, tissue, or other bodily fluids or substances.
- The intended use is a physical treatment accessory. The device's purpose is to physically interact with the skin and the effects of a laser to facilitate the removal of tattoo ink. This is a procedural aid, not a diagnostic test.
- The device description focuses on mechanical action. The description details how the device generates acoustic waves to address laser-induced effects in the skin. This is a physical mechanism, not a chemical or biological analysis.
Therefore, the Soliton Acoustic Wave Device (AWD) is a medical device used in a therapeutic procedure, not an In Vitro Diagnostic device.

Device Description
The Soliton Acoustic Wave Device (AWD) is designed as an accessory to laser treatments for tattoo removal. The AWD uses repeated, rapidly rising acoustic waves, releasing pigment particles from the pigment laden macrophage (PLM) and dissipating the laser-induced whitening. This allows multiple laser passes in a single session, resulting in fewer office visits. The Soliton AWD is composed of three parts: the Console, the Hand Piece and the connecting Cable. The Console supplies saline to the Hand Piece to enable formation of the shock wave within the acoustic pulse chamber. The Hand Piece generates acoustic waves in the saline. The acoustic waves pass through the acoustically transparent Window and acoustic ultrasound gel or similar hydrogel pad, which when placed against the surface of the tattoo to be removed, penetrates the skin to the typical depth of tattoo ink. The shape, frequency and repetition rate of these acoustic waves are optimized to diffuse gas bubbles (vacuoles) caused by the use of a Q-switched laser without damaging adjacent non-pigmented tissue. Removing them by using the Soliton AWD allows another Q-switched laser treatment to be performed immediately instead of waiting for the body to remove the gas pockets and heal over a period of 4-6 weeks between standard laser treatments.

Summary of Performance Studies
Animal Study Data: The AWD was evaluated using Gottingen Mini-pigs tattooed with multiple circular black tattoo spots. Tattoo sites were treated with either a single-pass Q-switched Nd: YAG laser treatment (Laser Only), or multiple-pass laser treatment with each laser treatment followed by an AWD application (Laser+AWD). Dermal clearing was assessed histologically and colorimetrically using a handheld colorimeter. The dermal effects of using AWD as an accessory to the laser were assessed histologically both immediately and at 48-72 hours post treatment. Additionally, the treatment sites were assessed photographically at 10-12 weeks. Key results: The results of this study demonstrate that when used as an accessory to a Q-switched Nd:YAG laser in the treatment of tattoos, AWD clears laser-induced dermal whitening. The use of Laser+AWD was also shown to be safe. After 10 to 12 weeks of healing the photographic appearance of the epidermis at the treatment sites was normal, showing no residual epidermal changes.
Clinical Study Data: The Soliton AWD was evaluated in a single-center, prospective study to assess the safety and efficacy of the device for its indicated use in tattoo removal. The clinical study enrolled 24 subjects with 35 tattoos at an investigational site in the U.S. The majority of subjects were female, Fitzpatrick Skin Type I-III, with a mean age of 34 years. Each tattoo was divided into 3 approximately equal areas. Each end area was designated for treatment with either a single laser pass (Laser Only) or multiple consecutive laser passes alternating with AWD (Laser+AWD). The middle area of the tattoo between the treated areas served as the control and was not treated. Each subject was assessed at baseline, post-treatment, and during follow up after treatment. For the primary endpoint analysis, the number of laser treatment passes delivered in a single session was recorded. In addition, the subjects' tattoos were evaluated by blinded independent evaluators, as well as the study investigator. Any potential safety effects were recorded. Key results: The primary effectiveness endpoint of the study was met as the mean number of laser passes delivered in a single treatment session with AWD treatment was 4.16, with a lower limit of 95% confidence interval of 3.97. The safety of the AWD was evaluated based on the adverse events reported during the study. All adverse events observed during the study were categorized as mild or moderate and were expected. All symptoms were completely resolved by the end of the study. No adverse events were identified as serious or severe. No patients asked to stop the treatment or dropped out of the study due to any adverse event.

Performance Data
Electrical safety and electromagnetic compatibility (EMC) testing for the AWD 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 and IEC 60601-1-2, Medical Electrical Equipment - Part 1-2: General Requirements For Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Compatibility -Requirements and Tests.
The biocompatibility of the AWD is established by biocompatibility evaluations consistent with the guidelines in 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 the testing results were found acceptable for software release.
All performance testing demonstrated that the AWD performs according to specifications and functions as intended.
Animal Study Data
The AWD was evaluated using Gottingen Mini-pigs tattooed with multiple circular black tattoo spots. Tattoo sites were treated with either a single-pass Q-switched Nd: YAG laser treatment (Laser Only), or multiple-pass laser treatment with each laser treatment followed by an AWD application (Laser+AWD). Dermal clearing was assessed histologically and colorimetrically using a handheld colorimeter. The dermal effects of using AWD as an accessory to the laser were assessed histologically both immediately and at 48-72 hours post treatment. Additionally, the treatment sites were assessed photographically at 10-12 weeks.
The results of this study demonstrate that when used as an accessory to a Q-switched Nd:YAG laser in the treatment of tattoos, AWD clears laser-induced dermal whitening. The use of Laser+AWD was also shown to be safe. After 10 to 12 weeks of healing the photographic appearance of the epidermis at the treatment sites was normal, showing no residual epidermal changes.
Clinical Study Data
The Soliton AWD was evaluated in a single-center, prospective study to assess the safety and efficacy of the device for its indicated use in tattoo removal. The clinical study enrolled 24 subjects with 35 tattoos at an investigational site in the U.S. The majority of subjects were female, Fitzpatrick Skin Type I-III, with a mean age of 34 years.
Each tattoo was divided into 3 approximately equal areas.

The middle area of the tattoo between the treated areas served as the control and was not treated. Each subject was assessed at baseline, post-treatment, and during follow up after treatment. For the primary endpoint analysis, the number of laser treatment passes delivered in a single session was recorded.

In addition, the subjects' tattoos were evaluated by blinded independent evaluators, as well as the study investigator. Any potential safety effects were recorded.
The primary effectiveness endpoint of the study was met as the mean number of laser passes delivered in a single treatment session with AWD treatment was 4.16, with a lower limit of 95% confidence interval of 3.97.
The safety of the AWD was evaluated based on the adverse events reported during the study. All adverse events observed during the study were categorized as mild or moderate and were expected. All symptoms were completely resolved by the end of the study. No adverse events were identified as serious or severe. No patients asked to stop the treatment or dropped out of the study due to any adverse event.
Based on the clinical performance as documented in the pivotal clinical study, the Soliton AWD was found to have a safety and effectiveness profile that is similar to the predicate device.
Summary of Substantial Equivalence
The AWD and the predicate device have the same intended use and similar indications for use. The use of an accessory to a Q-switched laser to dissipate whitening and allow multiple laser passes in a single session has previously been cleared by FDA for the predicate device. Both the AWD and the PFD patch cause the dissipation and absorption of the gas bubbles that cause whitening. As demonstrated in the performance testing, the AWD device performs similarly compared to the predicate device. Clinical testing confirms that the differences in technology compared to the predicate do not adversely impact performance. Therefore, the AWD is substantially equivalent to its predicate device.
Conclusions
Nonclinical and clinical testing of the AWD demonstrated that the device performs as intended with a favorable safety profile. Results in the clinical study were comparable to those reported for the predicate device, in support of substantial equivalence. Therefore, the AWD is substantially equivalent to the predicate device.
