Medtronic recalls certain implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) due to rare potential for reduced or no energy output during high voltage therapy. This may affect devices with specific glassed feedthroughs.
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 (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) that have a rare potential for reduced or no energy output during high voltage therapy. This could cause the device to fail to deliver necessary shocks in emergencies.
The device uses a specific type of glassed feedthrough that can sometimes fail to deliver the required energy during high voltage therapy (typically 0-12J). This is a rare occurrence but could prevent the device from functioning properly during critical medical events.
Individuals with Medtronic CRTD COBALT XT HF QUAD MRI IS4 DF4 devices (model DTPA2QQ) that were manufactured with a specific glassed feedthrough. This includes devices with the listed serial numbers and lot numbers.
Check if your device has the model number DTPA2QQ and the listed serial numbers (e.g., RTC605498S, RTC605500S) or lot numbers. This recall applies to devices sold between 2019 and 2:00 PM on 2023-08-01.
Verify your device's model number is DTPA2QQ and check the serial number against the list provided in the recall notice.
If your device is affected, contact Medtronic directly for further instructions on how to address the issue.
The affected devices have the model number DTPA2QQ.
Check your device's serial number against the list of affected serial numbers provided in the recall notice.
This is a rare potential for reduced or no energy output during high voltage therapy, but it does not pose a risk of serious injury in normal use.
