FDA's MAUDE database holds 215 reports that name the brand "Equalizer" (catheter percutaneous), received between October 2011 and November 2025; the manufacturer given most often on reports is Boston Scientific - Cork. Spellings of one product vary from report to report.

2 reports arrived in the 12 months to August 2026, down 50% 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 malfunction (92.6%) and injury (7.4%); across all catheter, percutaneous reports (product code DQY) death is recorded in 2.2% and malfunction in 74.7%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are material rupture (58.1%), deflation problem (6.5%) and detachment of device component (3.7%). The patient problems coded most often are no patient involvement, device embedded in tissue or plaque and bradycardia. 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."

How do I report a problem with a medical device?

Through FDA MedWatch (Form FDA 3500 for health professionals and consumers), or to the manufacturer. See the guide on how to report.

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.
