Premature Battery Depletion

Battery Performance Alert Update for Subset of ICD and CRT-D Devices

In October 2016, we notified physicians and patients that a subset of our ICDs and cardiac resynchronization therapy defibrillators (CRT-D) manufactured between January 2010 and May 2015 could potentially experience premature battery depletion. On August 29, 2017 we released a new Battery Performance Alert. It was recently approved by the U.S. Food and Drug Administration, and we plan to make the update available in your country once it is approved by the appropriate regulators.

The Battery Performance Alert is a tool designed to provide physicians with an earlier warning of potential premature battery depletion in devices subject to the October 11, 2016 Medical Device Advisory. The Battery Performance Alert uses an algorithm to detect abnormal battery behavior, which will reduce the already low risk of premature battery depletion in affected devices.

The Battery Performance Alert is available for the following devices subject to the October 2016 Medical Device Advisory: Fortify™, Fortify Assura™, Quadra Assura™, Quadra Assura MP™, Unify™, Unify Assura™, and Unify Quadra™. If you need to check if your device was subject to the October 2016 advisory, please see below.

If you have any further questions about the Battery Performance Alert, please contact your physician.

Frequently Asked Questions on the Battery Performance Alert

Global Medical Advisory Concerning Subset of ICD and CRT-D Devices

What you need to know
St. Jude Medical announced a global medical device advisory for a subset of our company’s Fortify™, Fortify Assura™, Quadra Assura™, Unify™, Unify Assura™ and Unify Quadra™ implantable cardiac defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) devices. This advisory was implemented after an analysis found that some devices manufactured prior to May 23, 2015 contain batteries which may run out of energy earlier than expected. This is termed: “premature battery depletion”.

The likelihood that this will impact your health is low, as the vast majority of devices have not experienced premature battery depletion.

Is your device subject to this advisory?
Please follow the steps below to determine if your ICD or CRT-D is subject to this global medical advisory. 

  1. Input your device’s model number and serial number, as instructed below, noting both are required.
  2. If your device is subject to this advisory, patients are advised to contact their physician for additional information, including any specific questions you may have related to this advisory.
  3. If your device is not subject to this advisory, you do not need to take any further action related to this advisory; your device is not impacted by this advisory.

If your device is subject to the advisory, here is what you need to do

  1. At-Home Monitoring - You may know that St. Jude Medical devices are capable of remote monitoring. This is a proven method of proactively monitoring devices without the need for an in-person office visit. If you do not already utilize remote monitoring for your device, your physician may soon discuss using Merlin@Home™ with you if they feel it is appropriate. Learn more about remote monitoring.

  2. Vibratory Alert - Your device is designed to deliver a vibratory alert to you when the battery is nearing its end of life. The device also delivers a notification to your physician with Merlin@Home or during a doctor visit. Your physician may have helped you experience a test alert to ensure you know what this alert feels like. If you experience a vibratory alert, we recommend that you contact your doctor promptly. 

  3. It is important for you to understand that if your device is not experiencing premature battery depletion, replacing your device is NOT recommended by St. Jude Medical or our medical advisory board. We are advising physicians on the recommended follow-up of devices subject to this advisory. Your doctor will determine the best course of action with you.

If you have any questions, we have also established a toll-free telephone hotline which is available in the U.S. for you to call: 1-866-915-5065

We sincerely apologize for any difficulties this current issue causes you or your caregivers. We take this matter very seriously. Please know that we are available to assist you if you are having problems with your device.
