June 21, 2012 — A class action suit has been filed against St. Jude Medical Inc. on behalf of purchasers of the company's defibrillator leads.
The Riata and Riata ST electrical wire leads were observed to wear through the silicone casing meant to contain them, going on to protrude into the body. Though sales of the Riata and Riata ST were discontinued, the complaint against St. Jude alleges that the company failed to disclose the full extent of the products' problems.
The complaint alleged that St. Jude failed to disclose that: The Riata and Riata ST leads were also associated with short circuits unrelating to the protruding wires that could have been more dangerous than the issue of protruding wires, and that the company's QuickSite and QuickFlex left-ventricular leads also suffered from the issue of protruding wires.
St. Jude disclosed the problems of QuickSite and QuickFlex in April, and the leads were subsequently discontinued. The company's stock declined more than 11 percent after the disclosure.
