1,137 medical device reports received by FDA name the brand "Sm304 M-Series W/Zoom" (stretcher wheeled powered); the manufacturer given most often on reports is Stryker Medical; received from August 2008 to July 2025. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

0 reports arrived in the 12 months to August 2026, against 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 (98.2%), injury (0.8%) and other (0.2%); across all stretcher, wheeled, powered reports (product code INK) death is recorded in 0.1% and malfunction in 95.3%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are device slipped (23.8%), break (20.3%) and device operates differently than expected (12.5%). The patient problems coded most often are no patient involvement, injury and electric shock. 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."
