About medical device recalls
Medical device recalls are the FDA's highest-volume stream. They cover implantable devices like pacemakers and joint replacements, hospital diagnostics and lab analyzers, surgical instruments, software-as-a-medical-device, and consumer-facing hardware like CPAP machines, blood-pressure cuffs, and glucose monitors. The volume comes from the wide range of products in scope and from the FDA's broad definition of 'corrective action' — software updates, IFU revisions, and labeling corrections all show up as recalls.
For Class I device recalls, the device's defect creates a reasonable risk of serious injury or death — these are the urgent ones. Class II covers issues that may cause temporary or medically reversible harm, often around accuracy or calibration. Class III is for products that don't comply with FDA rules but pose no real safety risk; in practice many software-update letters are Class III.
If you depend on a recalled device for ongoing care, don't disconnect or stop using it before talking to the prescribing clinician — interrupting therapy for a CPAP or a continuous glucose monitor can be more dangerous than the recall it's responding to. Almost every device recall offers a remedy that doesn't require you to surrender the device first.
