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 for Patients
St. Jude Medical knows that our patients may have questions related to our recently announced precautionary medical device advisory related to some of our implantable cardiac defibrillators (ICD) or cardiac resynchronization therapy (CRT-D) devices. To help you better understand what this advisory may mean, we have developed the following list of “Frequently Asked Questions.”
What is the issue?
St. Jude Medical has issued a precautionary global medical device advisory to notify physicians that a subset of our ICD and CRT-D devices may have the potential to experience premature battery depletion (batteries which may run out of energy earlier than expected) associated with lithium deposits.
How do I know if my device is subject to this advisory?
This advisory applies to a subset of our Fortify™, Fortify Assura™, Quadra Assura™, Quadra Assura MP™, Unify™, Unify Assura™ and Unify Quadra™ ICD and CRT-D devices manufactured before May 23, 2015.
If my device is included in the advisory, what is the likelihood that my device will experience premature battery depletion?
The likelihood that this will impact your health is low, as the vast majority of devices sold worldwide have not experienced premature battery depletion. Your physician will be able to help you understand how your battery is performing. In addition, your doctor can proactively check the operation of your device for signs of premature battery depletion through remote monitoring using your Merlin@Home system or in person visits. It is also important to know that your devices have built-in safeguards – such as vibratory alerts that would alert you to the need to replace your battery – to help you and your doctor know if your device may be nearing the end of their battery life.
Is it recommended that my device be replaced because of this advisory?
No. It is important 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 for you.
What is a lithium battery?
Lithium batteries are powerful and lightweight batteries used to power a wide range of devices. The medical device industry relies on lithium batteries for their ability to deliver energy to life-saving devices that require large amounts of power but that need to remain small in size for patients.
I have heard information recently about product recalls due to lithium battery problems in mobile phones and tablets. Are your lithium batteries the same as those batteries?
No. This advisory is completely unrelated. Our batteries are designed in a way that they cannot exhibit the types of issues with lithium-ion batteries used in cell phones and tablets. Our batteries are not rechargeable and have safety features that prevent extreme overheating conditions in case a short circuit were to occur as well as an airtight (hermetic) seal around the battery.
How can I tell if my device is experiencing
premature battery depletion?
When patients implanted with ICDs or CRT-D devices visit their physician, they often have the health of their battery checked to ensure normal operation. Your physician will be able to help you understand how your battery is performing. In addition, using remote monitoring through your Merlin@Home, your doctor can check on the status of your battery (in countries where the service is available).
If your device is reaching the end of its battery life, it is designed to both notify your physician and physically vibrate to make you aware. Your physician may help you test this vibratory alert during your next visit. If your vibratory alert occurs, please contact your physician.
What is a vibratory alert and what does it feel like?
Your device is designed to deliver a vibratory alert to you when the battery is nearing its end of life, meaning that the device itself will gently vibrate. It is a noticeable but gentle vibration.
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.
My serial number appears to be impacted by this advisory, but my physician has not contacted me. What should I do?
We have provided detailed information related to this advisory to your doctor. As each individual patient with a device impacted by this advisory has a unique medical condition, patients are advised to contact their physician for additional information, including any specific questions you may have related to this advisory.
I have a St. Jude Medical pacemaker. Should I be concerned about this advisory?
No, this advisory is limited to a subset of our high voltage devices. Low voltage devices, such as pacemakers, are not impacted.
I am scheduled to receive a St. Jude Medical ICD or CRT-D device. Should I be concerned?
No. All devices impacted by this advisory have been removed from hospital inventories and devices manufactured after May 23, 2015 are not impacted by this advisory.
I am interested in remote monitoring. Will St. Jude Medical provide me this service at no cost?
You should discuss enrollment with your doctor and if the system is appropriate for you. For devices impacted by this advisory, St. Jude Medical will provide access to our Merlin remote monitoring network and the Merlin@home unit at no cost. Learn more about remote monitoring.
