183 medical device reports received by FDA name the brand "Purge Cassette Gen 2, Sterile, Non QSK" (temporary non-roller type left heart support blood pump); the manufacturer given most often on reports is Abiomed - 1220648; received from September 2025 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

183 reports arrived in the 12 months to August 2026, with none 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 device problems coded most often are priming problem (42.1%), fluid/blood leak (24%) and failure to read input signal (19.1%). The patient problems coded most often are hemodynamic instability. 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."
