Medtronic recalls certain implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) with model DDMC3D4 due to rare potential for reduced or no energy output during high voltage therapy. This may affect device function but is not a common hazard.
There is a rare potential for reduced- or no-energy output during high voltage (HV) therapy (typically 0-12J) in implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) manufactured with a specific (glassed) feedthrough, including currently available ICDs and CRT-Ds.
Medtronic is recalling specific implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) with model number DDMC3D4. The recall is due to a rare potential for reduced or no energy output during high voltage therapy, which could affect device function. This is not a common hazard but requires attention.
The device uses a specific glassed feedthrough that can cause reduced or no energy output during high voltage therapy (typically 0-12J). This may lead to the device not functioning properly when needed, but the risk is rare and not a common hazard.
Patients with Medtronic ICDs or CRT-Ds manufactured with model number DDMC3D4 are affected. Most at risk are individuals who have received these devices as part of their heart condition treatment.
Check your device model number for DDMC3D4. The recall includes specific lot and serial numbers listed in the official notice. If your device has this model and matches the listed serial numbers, it is affected.
Verify your device model number is DDMC3D4. Check the serial numbers listed in the official recall notice to see if your device is affected.
This is a rare potential for reduced or no energy output during high voltage therapy, which could affect device function. It is not a common hazard and does not pose a significant risk to most users.
If your device is affected, you should check the official recall notice for specific instructions. The recall does not require immediate action but should be reviewed.
Check your device model number for DDMC3D4 and compare it to the list of affected serial numbers provided in the official recall notice.
