4,593 medical device reports received by FDA name the brand "Cardiomems Patient Electronic System" (system hemodynamic implantable); the manufacturer given most often on reports is St Jude Medical; received from May 2017 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
738 reports arrived in the 12 months to August 2026, close to the 758 of 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 (98.4%) and injury (1.6%); across all system, hemodynamic, implantable reports (product code MOM) death is recorded in 1.9% and malfunction in 62.4%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are material frayed (60.8%), device displays incorrect message (25%) and sparking (10.2%). The patient problems coded most often are electric shock, dyspnea and hypervolemia. 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."

Where this comes from. Counts are built from the openFDA Device Adverse Event (MAUDE) bulk export released 28 Sep 2026, which holds reports FDA received through 31 Aug 2026. Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. A report counts here when any device it lists carries this brand name after punctuation and capitalisation are normalised. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
