Medtronic recalls certain CRT-D defibrillators (model DTBB1D1) due to rare potential for reduced or no energy output during high voltage therapy. Affected devices may require replacement.
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 models of implantable cardioverter defibrillators (CRT-Ds) that have a rare risk of not delivering enough energy during high-voltage therapy. This could lead to ineffective treatment for heart conditions if the device fails to function properly.
The device uses a specific glassed feedthrough that can sometimes fail to deliver sufficient energy during high-voltage therapy (0-12 joules). This rare issue may cause the device to not function properly when needed, potentially leading to ineffective treatment of heart conditions.
People with Medtronic CRT-D defibrillators (model DTBB1D1) who were implanted with the device between 2017 and 2021 are likely affected. Those with heart conditions requiring a defibrillator are at the highest risk.
Check your device's model number (DTBB1D1) and lot/serial numbers listed in the recall notice. The devices were sold between 2017 and 2021 with specific serial numbers starting with BLO214...
Look for the model number DTBB1D1 on your device's label or documentation.
Reach out to Medtronic directly to confirm if your device is affected and get instructions for next steps.
The recall describes a rare potential for reduced or no energy output during high-voltage therapy, but it is not a risk of serious injury in normal use.
