What this means for you
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: This is a Class II medical device recall with potential for serious harm but no reported illnesses or injuries. The software defect could result in radiation therapy being delivered to the wrong anatomical location, meeting the criterion for a risk-of-harm product where injury has not yet been reported.
