FDA's MAUDE database holds 5,104 reports that name the brand "S-Icd System" (implantable cardioverter defibrillator), received between January 2013 and December 2018; the manufacturer given most often on reports is Guidant Crm Clonmel Ireland. Spellings of one product vary from report to report.

0 reports arrived in the 12 months to August 2026, and 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 event types recorded are injury (68.6%), malfunction (30.3%) and death (1.1%); across all implantable cardioverter defibrillator (non-crt) reports (product code LWS) death is recorded in 2.7% and malfunction in 37.4%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are over-sensing (24.7%), inappropriate/inadequate shock/stimulation (23.4%) and device sensing problem (12.9%). The patient problems coded most often are pocket erosion, ventricular fibrillation and ventricular tachycardia. 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."
