No
The 510(k) summary describes a laser system for surgical and therapeutic applications. There is no mention of AI or ML in the intended use, device description, or performance studies. The device operates based on laser technology and its physical properties.
Yes
The device is described as a surgical laser system with a wide range of indications for treating various medical conditions and performing therapeutic procedures in dentistry, dermatology, ENT, general surgery, podiatry, ophthalmology, gynecology, and genitourinary areas. Notably, it also directly lists "Nd: YAG laser (1064 nm wavelength) therapy: Temporary relief of muscle and joint pain and stiffness, arthritis pain or muscle spasm, temporary increase in local blood circulation and/or promoting relaxation of muscle," which explicitly identifies a therapeutic application.
No
The various uses described in the "Intended Use / Indications for Use" section are all therapeutic or surgical procedures (e.g., incision, excision, ablation, coagulation, removal of tissues, treatment of pain, hair reduction). There is no mention of the device being used to identify or characterize a disease, condition, or health status.
No
The device description clearly states it is a laser system family based on Er:YAG and Nd:YAG laser technology, including physical components like laser sources, optical cavities, an articulated arm, optical handpieces, and optical fiber delivery systems. This indicates it is a hardware device, not software-only.
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 intended uses and device description clearly indicate that this laser system is used for direct treatment and modification of tissues within and on the human body (dental procedures, surgical procedures, dermatological treatments, etc.).
- The device description focuses on the laser's physical interaction with tissue. It describes the wavelengths, energy levels, pulse durations, and how the laser is delivered to the target tissue for cutting, ablation, coagulation, etc.
- The intended uses are all therapeutic or surgical procedures. None of the listed indications involve analyzing samples taken from the body to diagnose a condition.
Therefore, the Fotona LightWalker laser system family, as described, is a therapeutic or surgical device, not an In Vitro Diagnostic device.

Device Description
The device is Fotona LightWalker laser system family (same as K191554). It is based on Er:YAG (2940 nm) and Nd:YAG (1064 nm) laser technology. It combines two flashlamppumped laser sources in one housing, with optical cavities containing the Er.YAG and Nd:YAG crystals. A diode aiming beam is combined with both therapeutic laser beams. The combined therapeutic and aiming beams are guided through an articulated arm to an optical handpiece (in the case of the Er: YAG laser), or, in the case of the Nd: YAG laser, through an optical fiber delivery system to an optical handpiece or to the bare fiber distal end.
The Er:YAG laser is capable of delivering up to 1.5 J of laser energy in pulses with durations of 50 - 1000 us and frequencies (repetition rates) of up to 50 Hz. The maximum average output power is 20 W. The laser is intended to be used for incision, cutting, ablation, vaporization and coagulation of soft and hard tissue in dentistry, dermatology and other surgical areas.
The Nd: YAG laser is capable of delivering up to 10 J of energy with pulse durations from 0.1-25 ms, and frequencies of up to 100 Hz. For dental indications it is capable of delivering laser pulses with durations of up to 650 us, frequencies (repetition rates) of up to 100 Hz and a maximum output power of 15 W. The laser is intended to be used for various intra oral treatments in dentistry, and for various surgical and aesthetic applications in dermatology and other surgical areas.

SUMMARY OF TECHNOLOGICAL CHARACTERISTICS
The Fotona LightWalker Laser System Family has either identical or similar applicable technological and design characteristics (design, chemical composition, energy source, wavelength, active medium, cooling system, power supply, beam delivery, controls, housing) as the previously cleared Fotona LightWalker Er:YAG/Nd:YAG Laser System Family (K191554), Biolase WaterLase Laser System Family (K190319) and Fotona Dynamis Pro Laser System Family (K182088). The output characteristics of the proposed device are similar to those of the predicate devices for the proposed intended use. All of the devices utilize class I aiming beams that pose a minimal hazard to the user when the devices are used properly. All systems are microprocessor controlled devices. The microprocessor control regulates normal operation, permits parameter selection and avoids hazard incidence. All systems utilize an internal closed loop water-air heat exchanger circuit for optimal thermal control of the laser cavity.
A comparison of the technical specifications for the intended use of the LightWalker Laser System Family with the previously cleared devices is provided in Table 1.
