What you need to know about the pacemaker firmware update
Firmware is a kind of software that is embedded in the hardware of the pacemaker device. Technological devices that use software, such as that in your pacemaker, require updates from time to time.
The update contains a software release that includes data encryption, operating system patches, and the ability to disable network connectively features, in addition to the firmware update.
The pacemaker devices to which this update applies include the RF telemetry versions of the following devices outside of the U.S.: Accent SR RF™, Accent ST™, Accent MRI™, Accent ST MRI™, Assurity™, Assurity +™, Assurity MRI™, Accent DR RF™, Anthem RF™, Allure RF™, Allure Quadra RF™, Quadra Allure MP RF™, Quadra Allure™, and Quadra Allure MP™.
This update will be released outside the U.S. following local regulatory approvals.
How likely is it that someone could gain unauthorized access to my device?
We have received no reports of unauthorized access to any patient’s implanted pacemaker. According to the advisory issued by the U.S. Department of Homeland Security, compromising the security of these devices would require a highly complex set of circumstances. 
Does this mean I should have my pacemaker removed?
No, preventative replacement is not necessary or recommended. Your pacemaker remains fully effective for providing pacing, as designed.
Should I continue to use my home monitor?
Yes, you should continue to use your Merlin@home™ device as it allows your physician to more frequently receive, assess, and monitor your device’s function.
What are the risks associated with the Getting the pacemaker firmware update?
We are anticipating the update will occur as planned. However, as with any firmware update, there is a very low rate of malfunction resulting from the update. We encourage you to discuss the risks and benefits of receiving the update with your doctor.
