Medtronic Recalls LifePak CR Defibrillators

Medtronic is recalling some LifePak CR defibrillators, an action the FDA considers a Class I recall. The product is used to treat patients in cardiac arrest. The devices were distributed from July 9 to Aug. 18, 2008, and are being recalled because an extremely humid environment may cause them to improperly analyze heart rhythm and possibly delay or fail to delivery therapy, according to an FDA statement.
