The plaintiffs sought to certify a class action against the manufacturers of Cook IVC filters, alleging negligent design and failure to warn of risks associated with the medical devices.
The court dismissed the certification motion.
While the plaintiffs satisfied the identifiable class and representative plaintiff criteria, and pleaded a valid cause of action for failure to warn, they failed to plead a valid cause of action for design negligence.
Crucially, the court found no 'some basis in fact' for the existence of any common issues regarding either design defect or duty to warn, as the evidence did not identify a specific design defect or inadequacy in the warnings provided to physicians.
Consequently, the preferable procedure criterion was also not met.
