FDA's MAUDE database holds 1,543 reports that name the brand "Cerenovus Enterprise" (intracranial neurovascular stent), received between July 2024 and August 2026; the manufacturer given most often on reports is Medos International Sarl. Spellings of one product vary from report to report.
951 reports arrived in the 12 months to August 2026, up 62% from 587 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 (93.7%), injury (5.8%) and death (0.5%); across all intracranial neurovascular stent reports (product code NJE) death is recorded in 6.8% and malfunction in 56.2%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are failure to advance (70.1%), premature activation (46.5%) and activation failure (16.3%). The patient problems coded most often are ischemia stroke, intracranial hemorrhage and swelling/ edema. 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."
