Intended Use

1550nm laser: Indicated for use in surgical applications requiring the vaporization, incision, excision, ablation, cutting and hemostasis, or coagulation of soft tissue, including meniscus cartilage, in conjunction with an imaging modality for medical specialties including: General Surgery, Orthopedics, Podiatry, Arthroscopy and Spinal Surgery. 980nm laser: Indicated for use to provide heating for the purpose of elevating tissue temperature for selected medical conditions such as temporary relief of pain, muscle spasms, and increase in local circulation.

Device Story

Regenalase is a portable laser console featuring a 1550 nm fiber laser and a 980 nm diode laser. Operated via a wired one-pedal footswitch, the system includes control electronics, an optical module, air cooling, and a touchscreen display. The 1550 nm laser delivers energy through cleared laser fibers for soft tissue surgery; the 980 nm laser uses a fiber delivery system with a handpiece and attachments for therapeutic heating. Used in clinical settings by healthcare providers, the device allows for adjustable power and pulse settings. By targeting water as a chromophore, the laser induces controlled thermal effects in tissue. The system provides clinicians with precise surgical control or therapeutic heating, potentially benefiting patients through effective tissue ablation or symptom relief.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing and ex vivo thermal performance evaluation. Ex vivo study compared thermal damage induced by 1550 nm and 1470 nm wavelengths across three tissue types under best-case, realistic-case, and worst-case energy deposition, showing comparable results.

Technological Characteristics

Portable console with 1550 nm fiber laser and 980 nm diode laser. Features touchscreen, air cooling, and wired footswitch. Fiber delivery system (400 um & 600 um). Conforms to IEC 60601-1, IEC 60601-1-2, IEC 60601-2-22, and IEC 60825. Biocompatibility per ISO 10993-1. Usability per ANSI/AAMI/IEC 62366-1.

Indications for Use

Indicated for patients requiring soft tissue surgical procedures (vaporization, incision, excision, ablation, cutting, hemostasis, coagulation) including meniscus cartilage, or patients requiring localized tissue heating for pain relief, muscle spasms, and increased circulation.

# Difference in Wavelength

The Subject device's laser wavelength is 1550 nm and the Predicate device's laser wavelength is 1470 nm. Both wavelengths are utilized in the industry for the same purpose: to heat the water contained in the tissue. Water is the predominant

chromophore in soft tissues that absorbs light at these wavelength range to produce heat.

To validate that the tissue effects produced by the 1470 nm and 1550 nm laser wavelengths are substantially equivalent, IPG Medical has conducted an ex vivo study comparing the thermal damage that could be induced by the two lasers side-by-side on three different tissue types for the best-case, realistic-case, and worst-case energy deposition from the two devices. The results show that the two devices produced comparable thermal damage.

# Difference in Pulse Duration

The Subject device's pulse durations are in the range between 10 ms and 2 s. The Predicate device's range is between 0.1 ms and 30 s. The Subject device's pulse durations fall within the range of the Predicate device's pulse durations. All possible combinations of power and pulse duration of the Subject device are a subset of all possible combinations of power and pulse duration of the Predicate device. Therefore, there are no new additional questions of safety and effectiveness raised since all the Predicate device's possible combinations of power and pulse duration are equivalent to those of the Predicate device.

# Difference in Pilot Beam wavelengths

The Subject device differences in pilot beam wavelengths, both being visible, do not raise any different concerns for safety.

# Non-Clinical Testing

# Risk analysis management

Risk management was performed according to ISO 14971 Third Edition 2019-11 Medical Devices -Application of risk management to medical devices and the FDA Guidance Document.

# Electrical safety and electromagnetic compatibility

The device conforms to the following standards.

IEC 60601-1:2005 C1:2009/(R) 2012 and A2:2010/(R) 2012 (Consolidated Text) Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601-1:2005, MOD).

# Software

Software verification and validation testing was conducted and documentation provided as recommended by the FDA's "Guidance for the Content of Premarket Submissions Contained in Medical Devices" and in ANSI/AAMI/IEC 62304:2006/A1:2016 Medical Device software- Software life cycle processes-including Amendment 1(2016). Device software verification and validation results were found acceptable for software release.

# Human Factors

Human Factors of the laser system was confirmed using ANSI/AAMI/IEC 1:2015+AMD1 2020 (Consolidated Text) Medical Devices Part 1 Application of Usability engineering to medical devices including Amendment 1 and the results found to be acceptable.

# Biocompatibility

# Patient Contacting Materials

Biocompatibility testing was conducted to confirm that the proposed patient contact attachments meet all the applicable biocompatibility requirements in compliance with ISO 10993-1 and the FDA Guidance "Use of the International Standard ISO 10993-1 'Biological evaluation of medical devices-Part 1: Evaluation and testing within a risk management process"

The results of the tests indicated that all success criteria were met with no issues.

# Bench Testing Data

The Regenalase Laser system performance characteristics were evaluated through testing and analysis of laser power output and beam quality where applicable. The ability of the new device to withstand variant operation, storage and transportation conditions were tested. The system testing (energy measurements, safety controls, emission indicator, fiber and aiming beam) was also completed. Testing shows that the device delivers set energy parameters within specifications and performs as intended.

There is a red line running horizontally through the middle of the letters, and two orange lines running vertically on either side of the "P".

### Thermal Performance Evaluation

Thermal damage was measured in three ex vivo tissue samples heated to 37 ºC due to the best-case, realistic-case and worst-case energy deposition from the subject and predicate devices. The data show that the induced damage was comparable between the subject and predicate devices for comparable energy deposition.

### Clinical Performance Data

Clinical trials were not deemed necessary as the new device is using similar technology and intended use as the Predicate device.

### Summary of Substantial Equivalence

The Regenalase Laser System and the Predicate device have the same intended use as surgical lasers with similar indications for use. The Regenalase Laser System presents similar technological characteristics as its Predicate device, including laser type, similar wavelength, device design, waveforms and pulsed mode characteristics and fiber size. Although there may be minor differences in the details of the device design, the differences do not raise different questions of safety or effectiveness.

### Conclusions

Comparison between the Regenalase Laser System and the predicate device shows that the Regenalase Laser System is as safe and effective as the predicate device. The subject device Regenalase Laser System has similar intended use and indications for use, technological characteristics, the same principle of operation, and similar performance as the predicate device.
