169 medical device reports received by FDA name the brand "Assurant Cobalt" (stent iliac); the manufacturer given most often on reports is Medtronic Ireland; received from January 2012 to May 2019. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
0 reports arrived in the 12 months to August 2026, and none in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (56.8%), injury (42%) and death (1.2%); across all stent, iliac reports (product code NIO) death is recorded in 2.9% and malfunction in 54.5%. Event type is the reporter's classification of the report, not a verified outcome.

The patient problems coded most often are intimal dissection, device embedded in tissue or plaque and reaction. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
