466 medical device reports received by FDA name the brand "IntellaNav MiFi? Open-Irrigated" (catheter percutaneous cardiac ablation for treatment of atrial flutter); the manufacturer given most often on reports is Boston Scientific; received from September 2018 to June 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

6 reports arrived in the 12 months to August 2026, down 54% from 13 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 (76.8%), injury (22.1%) and death (1.1%); across all catheter, percutaneous, cardiac ablation, for treatment of atrial flutter reports (product code OAD) death is recorded in 3.7% and malfunction in 48.6%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are material integrity problem (24%), fluid/blood leak (17.2%) and temperature problem (10.7%). The patient problems coded most often are pericardial effusion, low blood pressure/ hypotension and cardiac perforation. 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."
