FDA's MAUDE database holds 738 reports that name the brand "8CH Infinity DBS Flex Extn Kit, 50cm, B" (dbs extension), received between August 2017 and August 2026; the manufacturer given most often on reports is Abbott Medical. Spellings of one product vary from report to report.
142 reports arrived in the 12 months to August 2026, close to the 146 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 injury (99.3%) and malfunction (0.7%); across all stimulator, electrical, implanted, for parkinsonian tremor reports (product code MHY) death is recorded in 1.4% and malfunction in 50.2%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are high impedance (32.9%), fracture (8.9%) and impedance problem (6.6%). The patient problems coded most often are inadequate pain relief, movement disorder and failure of implant. 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."
