Implantable Cardioverter Defibrillators Risk Reduced or No Therapy Output
Certain Medtronic implantable cardioverter defibrillators and cardiac resynchronization defibrillators may fail to deliver energy during high-voltage therapy due to a specific feedthrough design issue. The recall affects 3,801 units distributed in the US and worldwide.
What this means for you
Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: FDA Class I classification requires a minimum severity score of 4. Although no illnesses or injuries have been reported and the hazard is theoretical (described as rare potential), the critical function at risk—high-voltage defibrillation therapy—justifies the FDA's highest recall classification.
Plain-English summary
Certain Medtronic implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) manufactured with a specific glassed feedthrough may deliver reduced or no energy output during high-voltage therapy. The devices affected include the ICD-DR DDMD3D1 PRIMO MRI model and other similar units using this feedthrough design.
The recall involves 3,801 units distributed in the United States and worldwide. High-voltage therapy typically operates in the 0-12 joule range. While the potential for this malfunction is described as rare, it could prevent essential defibrillation therapy when needed.
Patients and healthcare providers should contact Medtronic or their device clinic for evaluation and guidance regarding their specific device. The FDA classified this as a Class I recall due to the critical life-saving function at risk.
No injuries or illnesses have been reported in connection with this issue to date. However, the potential for therapy failure in a critical cardiac event justified the Class I recall designation.
