Dr. Mehmet Oz, best known for hosting a day-time talk show and being an FOO (Friend Of Oprah) will make an appearance in a legal feud between Medtronic and rival Edwards Lifesciences Corp.

The Business Journal reports that the physician-TV personality will testify as part of a lawsuit that Fridley-based Medtronic filed against Edwards.

Medtronic sued Edwards in 2011, alleging the Irvine, Cal. company infringed on four patents issued between 1999 and 2011 for two valve product lines and two other surgery devices.

Law360 reported that a Minnesota federal judge on Friday approved Edwards' request to depose Dr. Oz. The judge found that Edwards had good cause to take his deposition after the fact-discovery cutoff.

Court records show that Dr. Oz, a cardiothoracic surgeon, was involved in the development of the surgical technique, called the "Columbia noose," and the inventions at the center of the case.
