Indications for Use

The Orion Series Surgical Laser System and the Lyra Surgical Laser System are intended for the lightening and removal of unwanted body hair in Fitzgatrick Skin Ty I to VI using 1064 nm, Nd:YAG.

Device Story

Orion Series Surgical Laser System is a powered surgical laser console; includes power supplies, solid-state Nd:YAG laser resonator, and closed-cycle water-to-air cooling system. Operated by physician in clinical setting via keypad control panel and footswitch. Delivers 1064 nm near-infrared laser energy through fiber-optic handpiece to target tissue. Q-switched pulse duration (nanosecond range) enables selective photothermolysis; energy is preferentially absorbed by melanin in hair follicles, causing thermal damage. System features 1-20 Hz repetition rates for treatment speed. Output is controlled by user-defined operating parameters. Clinical benefit is reduction of hair density. Safety and effectiveness established via multi-center clinical study measuring hair density reduction and patient satisfaction.

Clinical Evidence

Multi-center, randomized, unblinded study of 70 patients (mean age 40.5, 79% female). Primary endpoint: hair density reduction. Mean hair reduction estimates: 26% (7 days), 49% (30 days), 36% (90 days). Patient satisfaction: 89% rated 'Fair' or better at 30 days. Success defined as ≥30% reduction and 'Fair' or better satisfaction; success rates were 38% (7 days), 86% (30 days), and 58% (90 days). One adverse event (1.4%) reported (erythema/burning sensation).

# DEVICE COMMON NAME

Laser Instrument, Surgical, Powered

# DEVICE DESCRIPTION:

The Orion Series Surgical Laser System consists of a movable console containing power supplies, a treatment laser on a solid optical deck, and a cooling system to dissipate the heat generated by the system. A keypad control panel with CRT enables the user to control the laser system operating parameters.

Surgical power is controlled via a footswitch. Laser power is emitted only when the footswitch is depressed. The delivery system is through fiber optics.

Five configurations are currently available:

12W KTP only, 208 VAC 12W KTP/30W Nd:YAG, 208 VAC 20W KTP only, 208 VAC 20W KTP/50W Nd:YAG, 208 VAC 50W Nd:YAG only, 208 VAC

# INDICATIONS FOR USE STATEMENT

The Orion Series Surgical Laser System (Q-Switched Nd:YAG configuration) is intended for the removal and reduction of unwanted hair.

#### CLINICAL SUMMARY:

This study incorporated a multi-center. randomized, unblinded design with an active, parallel control. The primary objective of the study was to establish the safety and effectiveness of the Laserscope Q-Switched Nd.YAG laser in the reduction of hair density in facial and non-facial anatomical areas. This clinical study was conducted in support of the 510(k) submission.

Convenience sampling was used to enter 70 patients at three geographically dispersed investigational centers. The average patient age was 40.5 ± 8.7 years and the majority of the patients were female (79%). Describing the patient demographics entailed specifying each patient's Fitzgerald Classification, hair color, hair thickness, and hair weight. Fifty percent of the patients had a Fitzgerald Classification of 11, 71% of the patients had black hair, 67% of the patients had course hair, and 54% of the patient's had hair described as heavy.

The number of sites treated was fairly uniform across all sites with some weighting toward Study Center #3 (45%). Among the 70 patients, 139 sites were treated. All, but one patient, had two treatments each. The treatment sites were stratified by location (facial). Facial sites made up 34% of the treatments and non-facial sites accounted for 66% of the treatments.

All treatments were performed between June 8 and October 12, 1998. Laser energy settings ranged from 100 J/cm² to 153 J/cm². The lower energy settings were confined to facial treatments, while the higher energy settings were required for the non-facial treatments. Total lasing time was restricted to 30 seconds for all patients.

One primary safety and three secondary efficacy study objectives were specified in the study protocol. In terms of safety, only one adverse event (i.e., extended erythema and burning

sensation resolved within 10 minutes of treatment) was reported at the time of treatment (1.4%). No adverse events or complications were reported beyond the time of treatment.

With regard to effectiveness, the investigator was to visually estimate percent reduction in hair density at each follow-up interval. The mean estimate of hair reduction was 26% at 7 days, 49% at 30 days, and 36% at 90 days post-treatment. When this analysis was further stratified by study center, it was found that Study Center #3 heavily influenced the lower estimates at 90 days post-treatment. Multivariate analysis of variance for longitudinal data revealed a significant difference in mean hair reduction over time and a significant study center effect. However, the location of the treatment had no impact on the estimates.

The patient was also queried as to her or his visual estimate of percent reduction in hair density at each follow-up interval. The patients' mean estimate of hair reduction was 33% at 7 days, 45% at 30 days, and 33% at 90 days post-treatment. The values and trends seen with the patients' estimates did not deviate greatly from that seen with the investigators. When this analysis was further stratified by study center, it was found that Study Center #3 again heavily influenced the lower estimates at 90 days post-treatment. The repeated measures multivariate analysis of variance revealed a significant difference in mean hair reduction over time, a significant study center effect, and a significant treatment location effect. These findings suggest great variance in patient estimates from center over time. Also, there was consistently lower hair reduction estimates reported across time for the non-facial sites, but the difference in estimates across time was not dependent upon the location of the treatment.

The last efficacy outcome was the patient satisfaction with treatment. The patients were asked to rank their treatments on a scale from 1 to 5 with one being worse than baseline and 5 being an excellent result. At seven days post-treatment, there was a 57% probability that the patients would rate their treatments as "Fair" or better. At 30 days post-treatment, there was an 89% probability that the patients would rate their treatments as "Fair" or better. At 90 days posttreatment, there was a 70% probability that the patients would rate their treatments as "Fair" or better.

A treatment success was based on the investigator estimate of ≥ 30% hair reduction and a patient satisfaction ranking of "Fair" or better. The overall success rates were 38% at seven days after treatment, 86% at 30 days after treatment, and 58% at 90 days after treatment. Although there was a significant study center effect and hair weight effect, very little difference was seen in overall success rates for facial and non-facial treatments.

# TECHNOLOGICAL CHARACTERISTICS

The Orion Series Surgical Laser System generates optical power by solid state Nd.YAG laser resonators. The system operates at wavelength (1064 nm). The near-infrared wavelentgh of

this laser system is within the range (600 - 1100 nm) The primary tissue chromophores this laser system to within the rare hemoglobin and melanin. The absorption coefficient competing for lasseration and member by melanin, and the longer wavelength allow greater dermal penetration. The operating mode of the laser system is Q-Switched.

The short pulse duration of this laser system enables it to be used for selective rho short purce the intended target tissue has a thermal relaxation time of approximately 1 priororyou. " the pulse duration of the treatment laser light for this laser is in the manosecond range. The pulses are, therefore preferentially absorbed by pigmented structures in the targeted tissue, causing selective heating and thermal damage of the pigmented structures. The Q-Switched Nd: YAG systems' faster repetition rates (1 - 20 Hz Orion) enables the user to conduct faster treatment sessions.

The laser system delivers spot sizes in the 2 - 4 mm range. A specification table for the Orion Series Surgical Laser System and predicate device is found in Table II.

# SUBSTANTIAL EQUIVALENCE DETERMINATION:

Since the Orion Series Surgical Laser System is substantially equivalent with respect to indications for use, materials, method of operation and physical construction to the predicate device, we believe they clearly meet the requirements for substantial equivalence according to 510(k) guidelines. Safety and effectiveness are reasonable assured, therefore justifying 510(k) clearance.
