Medtronic recalls specific CRT-D defibrillators (model DTBB2Q1) due to rare risk of reduced or no energy output during high voltage therapy. Affected units have unique serial numbers and were sold internationally.
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 certain implantable cardioverter defibrillators (CRT-Ds) that may have a rare issue causing low or no energy output during high voltage therapy. This could potentially affect the device's ability to treat heart conditions if the problem occurs during critical medical events.
The device uses a specific glassed feedthrough that may cause reduced or no energy output during high voltage therapy. This could happen during critical medical events when the device needs to deliver a shock to the heart.
People with implantable cardioverter defibrillators (CRT-Ds) using the specific model DTBB2Q1 are affected. Those with the recalled serial numbers are most at risk.
Check for the model number DTBB2Q1 on your CRT-D device. Look for serial numbers starting with BLQ600033S through BLQ600038S. These units were sold internationally.
Identify if your device is a CRT-D model DTBB2Q1 with serial numbers starting with BLQ600033S through BLQ600038S.
The recall describes a rare potential for reduced or no energy output during high voltage therapy, but it is not stated to cause serious injury or death in normal use.
Check for the model number DTBB2Q1 and serial numbers starting with BLQ600033S through BLQ600038S on your CRT-D device.
The recall does not specify a remedy, so affected users should contact Medtronic directly for guidance.
