Glossary Medical Device

instrument or apparatus used to diagnose or treat medical conditions

A medical device is any instrument, apparatus, implement, machine, or related article used to diagnose, prevent, monitor, treat, or alleviate disease or injury in humans. Unlike drugs, which achieve their primary effect through chemical action, medical devices exert their effects through physical or mechanical means. Examples include pacemakers, MRI machines, and even simple items like bandages and thermometers.
