Two medical device companies that were hit last month with a $33 million verdict over their allegedly defective blood filter devices are seeking to have the award overturned.

Rex Medical and Argon Medical Devices have filed a post-trial motion in the case, captioned Reed-Brown v. Rex Medical, in which a jury handed up the multimillion-dollar award Oct. 28. The motion argues that Philadelphia Court of Common Pleas Judge Michael Erdos, who oversaw the nearly three-week trial, among other things, allowed the jury to hear improper evidence.
