A Danville chiropractor and marketing consultant will pay $1.125 million to settle a lawsuit that he made false claims about a device he marketed to treat back pain.

Benjamin Altadonna created a fraudulent national marketing campaign for the DRX 9000, a device that aims to treat back problems using spinal decompression, according to a news release from the Monterey County District Attorney's Office, which joined District Attorney offices throughout the Bay Area in the fraud lawsuit.

The marketing materials falsely pitched the device as "patented," "breakthrough medical technology," and "developed by NASA," according to the release.

The FBI raided the device's manufacturer in 2007, the same year two Monterey County chiropractors were fined for making misleading claims about the device.

Those Monterey County investigations led to Altadonna, who sold marketing materials for the device to thousands of chiropractors across the country. Altadonna got sales commissions from the company that manufactured the device, according to the release.
