FDA's MAUDE database holds 180 reports that name the brand "Cobra Pzf" (stent coronary delivery system), received between September 2017 and November 2021; the manufacturer given most often on reports is Celonova Biosciences. Spellings of one product vary from report to report.
0 reports arrived in the 12 months to August 2026, and 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 injury (60%), malfunction (21.7%) and death (18.3%); across all stent, coronary reports (product code MAF) death is recorded in 7.6% and malfunction in 40.4%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are device dislodged or dislocated (28.9%), failure to advance (17.2%) and material deformation (5.6%). The patient problems coded most often are stenosis, angina and death. 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."
