Clinical investigation: a temporal relationship exists between the pd therapy with the liberty cycler set and the patient¿s peritonitis event.However, currently there is no objective evidence that a liberty cycler set malfunction or product deficiency caused this event.Peritonitis is a well-documented complication in pd patients.Based on the available information, the peritonitis event can be attributed to patient breach in aseptic technique due to patient not wearing a mask during pd exchange and not performing proper hand hygiene.The plant investigation is in process.A supplemental mdr will be submitted upon completion of this activity.
