How Device Recall Classifications Work

The FDA assigns a classification to every medical device recall based on a health hazard evaluation. This evaluation considers the type of defect, the likelihood that patients will be harmed, the severity of potential health effects, and the clinical context in which the device is used.

Class I recalls are the most serious. They are issued when there is a reasonable probability that use of the device will cause serious health problems or death. Common triggers include software malfunctions in life-sustaining devices, contaminated implants, and electrical failures that could lead to patient injury.

Class II recalls cover situations where using the device may cause temporary or medically reversible adverse health effects, or where the probability of serious health consequences is remote.

Class III recalls involve devices unlikely to cause any adverse health effects. These often arise from labeling errors, minor manufacturing deviations, or cosmetic defects that don't affect the device's safety or performance.
