521 medical device reports received by FDA name the brand "Sensor MMT-7020B Enlite3 US" (artificial pancreas device system single hormonal control); the manufacturer given most often on reports is Medtronic Minimed; received from August 2017 to July 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

23 reports arrived in the 12 months to August 2026, up 77% 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 (80.4%) and injury (19.6%); across all automated insulin dosing device system, single hormonal control reports (product code OZP) death is recorded in 0.1% and malfunction in 85.6%.

The patient problems coded most often are hyperglycemia, hypoglycemia and blood loss. 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."
