Are St. Jude Medical’s Strongest Investors Worried About This Product’s Health?

So far in 2012, St. Jude Medical Inc.’s (NYSE:STJ) shares are up 3.97 percent. On Tuesday, the company’s stock price fell more than six percent after an April 18 report came out on a single unfavorable event involving Durata, its implantable defibrillator lead.

The report had been in the FDA’s Maude database of adverse events, according to Barron’s, and it said that a fluoroscopy of Durata lead had shown protruding cables–a problem found in one of the company’s older, discontinued leads. A doctor had reported the event but it wasn’t sent to the manufacturer; the FDA received it on May 2.

With the news of the unfavorable report for Durata, will St. Medical’s largest shareholders decrease their positions? 566 institutional firms indicated owning shares of St. Jude Medical Inc.
