FDA's MAUDE database holds 187 reports that name the brand "CGuard Prime Carotid Stent System" (carotid stent system), received between September 2025 and August 2026; the manufacturer given most often on reports is Inspiremd. Spellings of one product vary from report to report.

187 reports arrived in the 12 months to August 2026, with 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 (81.8%), injury (17.1%) and death (1.1%); across all stent, carotid reports (product code NIM) death is recorded in 8% and malfunction in 26.7%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are activation failure (36.9%), difficult or delayed activation (29.4%) and insufficient device problem information (23%). The patient problems coded most often are obstruction/occlusion, thrombosis/thrombus 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."
