2,155 medical device reports received by FDA name the brand "AMS 800 Artificial Urinary Sphincter" (device incontinence mechanical/hydraulic); the manufacturer given most often on reports is Boston Scientific; received from January 2019 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

1,149 reports arrived in the 12 months to August 2026, up 17% from 982 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 (98.8%) and malfunction (1.2%); across all device, incontinence, mechanical/hydraulic reports (product code EZY) death is recorded in 0% and malfunction in 2.8%.

The patient problems coded most often are urinary incontinence, erosion and muscle weakness/atrophy. 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."
