#### Comparison of Technological Characteristics with the Predicate Devices (continuation)
### Performance Data
The safety and effectiveness determination of the 445nm subject device compared to the primary predicate with wavelength 532nm is supported by the Electrical Safety, EMC, Software, and non-clinical comparison bench tests provided in the submission.
### Non clinical testing :
A comparison bench test between 445 nm and 532 nm laser devices was conducted with the purpose of demonstrating that the Wolf 445 nm provides as safe & effective performance data as a KTP Laser (532 nm) in terms of tissue interaction processes.
The cut depth (effectiveness) and thermal damage (safety) zones of the 445nm laser device were used for the purpose of comparison.
Following the tests, histological samples were evaluated for areas of visible alteration of depth and width of the incision as well as zones of thermal and mechanical damage created by the tests.
# Electrical Safety and EMC testing:
Electrical safety and EMC testing were conducted on the Wolf 445nm, consisting of Diode laser console and optical fibers.
The Wolf 445nm system has been tested for Electrical Safety according to IEC 60601-1:2005 A1:2012 and /or EN 60601-1:2006/A1:2013, for Laser Safety according to IEC 60825-1: 2014 (edition 3.0), for Safety of laser according to IEC 60825-1:2014 and IEC 60601-2-22:2007/A1:2012, for Usability with IEC 60601-1-6:2010/A1:2013 and IEC 62366:20017, AMD1:2014.
Electromagnetic Compatibility was tested according to IEC 60601-1-2:2014, (edition 4.0).
### Software Verification and Validation Testing
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices."

# 510(k) Summary - K192272
The software is considered as a moderate level of concern and the documentation was provided accordingly.
### Summary
Based on the clinical performance, technological characteristics and performance data as documented in this submission, the Wolf 445nm was found to have a safety and effectiveness profile that is similar to the predicate devices.
# Conclusion
The safety and effectiveness determination between the subject and the predicate devices is supported by the performance data provided in the submission, the electrical and EMC testing, the software verification and validation testing and the non-clinical bench test demonstrating that the Wolf 445nm performs comparably to the predicate device that is currently marketed for the same intended use.
