Medtronic recalls certain implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) with a specific glassed feedthrough that may cause reduced or no energy output during high voltage therapy. This rare issue could affect device function but is not immediately dangerous.
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 use a specific glassed feedthrough. This design flaw may cause the device to produce reduced or no energy during high voltage therapy, potentially affecting treatment effectiveness. The risk is rare and not immediately life-threatening.
The device uses a glassed feedthrough that can sometimes fail to deliver proper energy during high voltage therapy (typically 0-12J). This may reduce or stop the device's ability to treat heart rhythm issues, but it does not cause immediate injury or death.
Patients with Medtronic ICDs or CRT-Ds manufactured with the specific glassed feedthrough (model DDME3D4) are affected. Most patients are at low risk as the issue is rare and not immediately dangerous.
Check your device model number (DDME3D4) and lot/serial numbers listed in the recall notice. The product is identified by the GTIN 00763000001582 and specific serial numbers starting with CWT.
Look for the model number on your device (DDME3D4) and check if your serial number starts with CWT.
If you have the recalled device, contact Medtronic directly for further instructions.
No, this recall is for a rare issue that may reduce or stop energy delivery during high voltage therapy. It does not cause immediate injury or death.
Medtronic will provide instructions for you to check if your device is affected. They may send a replacement or repair kit if needed.
Check your device model number (DDME3D4) and serial number (starting with CWT) against the list of affected units provided in the recall notice.
