Additional Manufacturer Narrative
The plant investigation is in process.A supplemental mdr will be submitted upon completion of this activity. clinical investigation: there is a temporal relationship between peritoneal dialysis and utilization of the liberty select cycler and liberty cycler set and the patient event of relapsing peritonitis with hospitalization.However, there is no documentation in the complaint file to show a causal relationship between the adverse event and use of the liberty select cycler and liberty cycler set.Additionally, there is no allegation of a device malfunction or deficiency, or cycler set defect reported for this event.Although a definitive cause of the relapsing peritonitis was not determined, the culture result of acinetobacter suggests a lack of aseptic technique or a touch contamination event.This genus is broadly distributed in nature as a saprophytic bacteria in soil, sewage, water, skin, the gastrointestinal tract and the hospital environment.This organism is also known to have an ¿inherent ability to develop antibiotic resistance.This could account for the relapsing peritonitis.Based on the available information and no allegation or evidence of a malfunction, deficiency, or defect, the liberty select cycler and liberty cycler set can be excluded as the cause of the patient¿s peritonitis event.
