A Minnesota woman has admitted to running a nationwide fraud scheme that federal prosecutors say caused millions in losses through the sale of counterfeit medical devices.

Tammy Wadsworth, 63, pled guilty Wednesday in federal court to possessing altered, forged, or counterfeit medical products which she claimed could cure serious illnesses and diseases.

Wadsworth, the founder of Pain, Injury and Brain Centers of America, operated out of Winona and expanded her franchise model to sites across the country starting in 2017. Prosecutors say she recruited franchise owners with promises of “state-of-the-art” artificial intelligence therapy that could “treat the untreatable.”
