Item 8.01    Other Events

Further Developments In Cases Involving Products with Silzone Coating

On October 12, 2005, the United States Court of Appeals for the Eighth Circuit issued a decision reversing prior rulings by District Court Judge John Tunheim which certified several class actions involving St. Jude Medical’s heart valve products with Silzone coating.

More specifically, the 8^th Circuit ruled that the District Court erred in certifying a consumer protection class seeking damages based on Minnesota’s consumer protection statutes, and required the District Court in further proceedings to conduct a thorough conflicts-of-law analysis as to each plaintiff class member before applying Minnesota law.

In addition, in this October 12, 2005 opinion, the 8^th Circuit also ruled that the District Court’s certification of a medical monitoring class was an abuse of discretion and thus reversed the District Court’s certification of a medical monitoring class involving the products with Silzone coating.

The decision is available on the 8^th Circuit Court’s website at:   http://www.ca8.uscourts.gov/opndir/05/10/043117P.pdf
