561 medical device reports received by FDA name the brand "Venovo Venous Stent" (venous stent); the manufacturer given most often on reports is Angiomed & Medizintechnik Kg; received from November 2020 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
74 reports arrived in the 12 months to August 2026, up 23% from 60 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 (83.8%), injury (15.7%) and death (0.5%); across all stent, iliac vein reports (product code QAN) death is recorded in 0.6% and malfunction in 57.4%.

The device problems coded most often are activation failure (67%), material deformation (9.3%) and fracture (8%). The patient problems coded most often are thrombosis/thrombus, restenosis and obstruction/occlusion. 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."
