The cycler was returned with no evidence of dried fluid residue.The blank display problem was duplicated when turning on the cycler.Replacement of the inverter board repaired the display failure.Cycler passed all testing after inverter board replacement.Per the fresenius clinical investigation: there is no contact between dialysis solution and cycler which would cause an infection.There was no report of a fluid leak.There were no reported problems with the cycler just prior to the peritonitis event.Most common cause of peritonitis is touch contamination.The peritonitis event predated the tech support call.The hospitalization event was due to catheter problems.Per patient's nurse, the patient continues on continuous cycling peritoneal dialysis using the liberty cycler.This is a retrospective mdr being submitted by fresenius medical care as a remediation action committed to fda regarding all potential adverse events received between (b)(4) 2011 to (b)(4) 2013.
