Phototherapy Device Canopy May Detach Due to Weld Failure

THOR NovoTHOR phototherapy devices (Model S2188) may have a failed welded nut causing the canopy gas strut to detach, making the canopy difficult to lift. Eighty units have been recalled.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This is an FDA Class II medical device recall involving a structural defect—a failed welded nut that causes a gas strut to detach. Although no injuries have been reported, the defect creates a risk of harm through canopy instability and difficulty in safe operation, meeting the criterion for Score 3: risk-of-harm products where injury has not yet been reported.

Plain-English summary

THOR Photomedicine Ltd is recalling the NovoTHOR and NovoTHOR XL phototherapy devices (Model S2188) used for topical heating to provide temporary relief of muscle and joint pain.

A welded nut that secures the gas strut supporting the canopy may fail and shear off. When this occurs, the gas strut becomes detached from one side of the canopy, making the canopy difficult to lift.

Sixty-six units were distributed in the United States across multiple states (AK, AZ, CA, CO, CT, FL, GA, HI, ID, IN, MA, MD, NC, ND, NJ, NV, NY, OR, PA, TX, UT, VA, WA, WI, WV), and fourteen units were distributed internationally in Australia, United Kingdom, Austria, Ireland, Italy, Lithuania, Netherlands, Poland, Serbia, Slovakia, and Spain.
