Medtronic recalls specific implantable cardioverter defibrillators (CRTDs) with model DTMB2D4 due to rare risk of reduced or no energy output during high voltage therapy, potentially affecting device function.
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 (CRTDs) with model number DTMB2D4. These devices have a rare potential for reduced or no energy output during high voltage therapy, which could affect their ability to treat heart conditions. This is a very uncommon issue but requires attention.
The hazard involves a rare potential for reduced or no energy output during high voltage therapy (typically 0-12J) in the device's specific glassed feedthrough. This could affect the device's ability to deliver necessary electrical shocks for heart rhythm management.
People with Medtronic implantable cardioverter defibrillators (CRTDs) manufactured with model number DTMB2D4 are affected. Most users are likely to be safe, but those with the specific model should check if they have the recalled device.
Check if your device has the model number DTMB2D4. The recall includes specific lot and serial numbers listed in the official record. If you have a Medtronic CRTD, check the device label for the model number and serial number.
Look for the model number DTMB2D4 on your device label to determine if it's affected.
If your device is affected, contact Medtronic directly for further instructions.
