Injury Board -- Avery deGroh of McHenry, Illinois, was just three when the Medtronic lead to her implanted heart defibrillator fractured, sending nine shocks to her heart, similar to the sensation of being electrocuted nine times. When the episode occurred, Avery thought monsters were attacking her as her mother felt the shocks going through her little girl’s body. Avery’s lead was Medtronic’s Sprint Fidelis model that was recalled by Medtronic and the FDA in October 2007, nine months after Avery’s incident.
