AI Incident Database: AI-Enabled TruDi Navigation System Was Alleged to Have Contributed to Patient's Stroke During June 2022 Sinus Procedure

Patient Erin Ralph allegedly suffered carotid-artery injury and a stroke after a June 23, 2022 sinus procedure in Texas in which surgeon Marc Dean reportedly used Acclarent's AI-enabled TruDi Navigation System. Ralph's lawsuit alleged TruDi misinformed Dean about the instrument's position inside her head; Acclarent and Integra LifeSciences, which later acquired Acclarent, reportedly denied a causal connection.
