Fridley-based Medtronic, Inc., disclosed in a Wednesday regulatory filing that it has been subpoenaed for information relating to some of its neurostimulation devices.

According to the U.S. Securities and Exchange Commission (SEC) filing, the company received the subpoena on October 14 from the United States Attorney's Office for the Western District of New York.

The subpoena requests information about the company's sales, marketing, and reimbursement support practices regarding certain neurostimulation devices. The company said it relates to the Health Insurance Portability & Accountability Act of 1996, also called HIPAA.

A copy of the subpoena was not immediately available, but Medtronic said in the SEC filing that it is fully cooperating with the investigation. Medtronic spokesman Brian Henry declined to comment.

According to the company's Web site, Medtronic manufactures and sells about 15 neurostimulator devices.

Shares of the company's stock were up about 1.4 percent in Thursday afternoon trading.

Medtronic is among Minnesota's 10-largest public companies based on revenue from its 2010 fiscal year, which totaled $15.8 billion.
