456 medical device reports received by FDA name the brand "Endeavor Rx" (stent coronary drug-eluting); the manufacturer given most often on reports is Medtronic Ireland; received from April 2008 to October 2024. 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, against 6 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 injury (62.5%), death (35.3%) and malfunction (2.2%); across all coronary drug-eluting stent reports (product code NIQ) death is recorded in 8.7% and malfunction in 42.8%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are occlusion within device (3.1%), device remains implanted (2.6%) and insufficient device problem information (2.6%). The patient problems coded most often are death, myocardial infarction and stroke/cva. 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."
