590 medical device reports received by FDA name the brand "Zilver Ptx 35 Drug-Eluting Stent" (niu stent superficial femoral artery drug-eluting); the manufacturer given most often on reports is Cook Ireland; received from March 2014 to July 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

16 reports arrived in the 12 months to August 2026, down 62% from 42 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 (62.2%), malfunction (37.1%) and death (0.7%); across all stent, superficial femoral artery, drug-eluting reports (product code NIU) death is recorded in 0.6% and malfunction in 29.4%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are activation, positioning or separation problem (14.6%), occlusion within device (12.7%) and fracture (11.7%). The patient problems coded most often are restenosis, reocclusion and stenosis. 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."
