Device Lookup

For Assurity, Endurity, Zenex*, and Zenus* Pacemaker Epoxy Mixing Notification

Product Advisories 

Beginning February 2025, Abbott informed customers of the potential for a device malfunction affecting a subset of Assurity™, Endurity™,  Zenex™*, and Zenus™* pacemakers.  This issue may result in incomplete mixing of epoxy during manufacturing and, with time, may permit moisture ingress into the pulse generator header, introducing a risk of interrupting device functionality. Affected devices were manufactured between August 2019 and June 2020. The specific manufacturing equipment associated with this issue is no longer in use. No affected devices remain available for implant.
