K050668 is an FDA 510(k) clearance for the GRT LITE, MODEL 8-A. Classified as Powered Light Based Laser Non-thermal Instrument With Non-heating Effect For Adjunctive Use In Pain Therapy (product code NHN), Class II - Special Controls.

Submitted by Grt Solutions, Inc. (Los Angeles, US). The FDA issued a Cleared decision on February 3, 2006 after a review of 325 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Physical Medicine FDA review panel, regulated under 21 CFR 890.5500 - the FDA physical medicine device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Physical Medicine review framework, consistent with the majority of Class II 510(k) submissions.

Device Classification

Product Code NHN Powered Light Based Laser Non-thermal Instrument With Non-heating Effect For Adjunctive Use In Pain Therapy
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 890.5500
Definition A Laser (light Amplification By Stimulated Emission Of Radiation) Based Device Having Coherence, Collimated And Typically Monochromatic Radiation. This Device Emits Energy In The Infrared Or Other Wavelengths, Provides Non-heating And Non-thermal Effect, And Is Indicated For Adjunctive Use In Pain Therapy Or Related Indication. It Does Not Provide Therapeutic Topical Heating. The Classification Regulation For Infrared Lamps Describes A Device That Emits Energy In The Infrared Wavelength To Provide Topical Heating And That Is Not Limited To Adjunctive Use.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Physical Medicine devices follow this clearance model.
