156 medical device reports received by FDA name the brand "Vercise Pc" (stimulator electrical implanted for parkinsonian tremor); the manufacturer given most often on reports is Boston Scientific Neuromodulation; received from January 2018 to July 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
15 reports arrived in the 12 months to August 2026, up 275% from 4 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 (85.9%), malfunction (12.8%) and death (1.3%); 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 battery problem (26.3%), premature discharge of battery (14.1%) and unexpected therapeutic results (10.3%). The patient problems coded most often are fall, inadequate pain relief and neurological deficit/dysfunction. 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."
