> "A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide."

Classification: Class II

Product Code: GEX

- 4. Predicate Device(s)
The LightScalpel CO2 Laser System is equivalent in operating principles and intended uses to the Luxar LX-20SP and DEKA SmartXide CO2 Laser Systems.

- 5. Device Description and Function
The LightScalpel LS-10 laser system is a mobile platform that utilizes a radio frequency (RF) excited carbon dioxide (CO₂) laser tube to produce an infrared beam at a nominal 10.6 µm wavelength at powers adjustable from 2 to 10 Watts Continuous Wave (CW). Laser energy is conducted to the point of application by a flexible fiber wavequide and handpiece assembly. Laser system operation is controlled by operator input on a touch-screen display panel. The RF laser drive is modulated to provide additional pulsed and superpulse emission modes selected from the laser system control panel.

## 8. Performance Testing

The LightScalpel LS-10 CO2 Laser System has been evaluated for performance equivalent to predicate devices through a combination of (1) verification and validation tests per product requirements and specifications and (2) inspections and tests derived from applicable regulations and safety standards as noted below.

- 21 CFR 1040, Performance Standards for Light-emitting Products
- IEC 60601-1, Medical Electrical Equipment Part 1: General requirements for basic safety and essential performance
- IEC 60601-2-22. Medical electrical equipment Part 2-22: Particular requirements for basic safety and essential performance of surgical, cosmetic, therapeutic and diagnostic laser equipment
- IEC 60825-1, Safety of laser products Part 1: Equipment classification, requirements and user's guide
- 9. Animal and Clinical Testing

Device performance evaluation did not involve Animal of Clinical Testing.

- 10. A comparison between the LS-10 and the predicated carbon dioxide lasers showed that these devices have similar laser characteristics and output parameters and therefore a determination of equivalence can be made between the predicate devices and the LS-10.
