The adverse-event profile breaks down across 5 distinct event types and 13 reported patient-outcome categories, giving a multi-dimensional view that goes beyond a single headline number. A total of 3 distinct product-problem codes appear in the reports, with Loose or Intermittent Connection topping the list at 4 reports. Reports are associated with 10 different manufacturers in the MAUDE record, reflecting both OEMs and repackagers of this device category.

Annual reporting volume is tracked across 25 years of MAUDE data, with the peak single-year volume reaching 171 reports — trend shape often reflects changes in device adoption, reporting rules, or FDA enforcement focus rather than underlying device behavior alone. Events are documented across 11 reported care-setting categories (hospital, home, ambulatory surgery center, etc.). All figures reflect the openFDA MAUDE snapshot last refreshed on 2026-05-15.
