FDA Product Code NHN: Powered Light Based Laser Non-thermal Instrument With Non-heating Effect For Adjunctive Use In Pain Therapy

Non-thermal laser therapy uses light energy without generating destructive heat, expanding its safe applications in rehabilitation. FDA product code NHN covers powered non-thermal light-based laser instruments.

These devices deliver low-level laser or light energy to tissue to modulate cellular activity, reduce inflammation, and promote healing — without thermal damage. They are used in pain management, wound healing, and musculoskeletal rehabilitation.

NHN devices are Class II medical devices, regulated under 21 CFR 890.5500 and reviewed by the FDA Physical Medicine panel.
