Feds subpoena Medtronic

The U.S. Department of Justice has sent a subpoena to medical device maker Medtronic Inc. as part of an investigation into unapproved, or "off-label," uses of its Infuse spinal graft. Bill Hawkins, chief executive for Medtronic, revealed the subpoena during a Tuesday conference call with analysts, but he declined to elaborate on what was requested.

"For years, Medtronic has had strict guidelines in place on appropriate promotion of products according to labeled indications," Hawkins said. "We are complying appropriately with the DOJ's request."
