TACOMA — A U.S. Army major who served as the chief cardiologist at Madigan Army Medical Center has said he illegally accepted money from a medical-device company while on the government payroll.

The U.S. Attorney’s Office says Maj. Jason Layne Davis pleaded guilty Wednesday in federal court in Tacoma to a charge of accepting money from an illegal source. He took $5,000 from Guidant Sales, a subsidiary of Boston Scientific.

Guidant agreed to pay $600,000 last fall to settle claims it provided money, meals and gratuities to the 38-year-old Davis so that he would use the company’s devices in cardiac procedures and encourage his colleagues to do likewise.

U.S. Attorney Jenny Durkan says military doctors must owe their allegiance to the soldiers they treat, not to drug companies or medical-device manufacturers.

The misdemeanor charge carries up to a year in prison and a $100,000 fine.
