401 medical device reports received by FDA name the brand "Flexor High-Flex Ansel Guiding Sheath" (dyb introducer catheter); the manufacturer given most often on reports is Cook; received from January 2012 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

19 reports arrived in the 12 months to August 2026, close to the 20 of 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 (69.6%), injury (29.9%) and death (0.5%); across all introducer, catheter reports (product code DYB) death is recorded in 3.3% and malfunction in 64.6%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are material separation (39.2%), detachment of device or device component (15.5%) and unraveled material (10.7%). The patient problems coded most often are no patient involvement, foreign body in patient and device embedded in tissue or plaque. 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."
