It was reported that a patient experienced air in the patient line of a homechoice cassette without an alarm.This occurred during priming for peritoneal dialysis (pd) therapy.The patient was connected at the time of the event.There was nothing unusual found during troubleshooting that would cause or contribute to the event; however, it was reported that the patient had repeatedly re-primed the set and still the patient had air enter their system causing pain.There was no physical damage or kinks in the set; however, the patient believed this issue was caused by something wrong inside the tubing of the cassette.The patient ended their therapy session and did not complete pd therapy.There was no patient injury or medical intervention associated with this event.No additional information is available.

Additional information was added to d10, h3, and h6.H10/h11: two (2) companion samples and six (6) actual samples were received for evaluation.A visual inspection was performed, and it was noted that indentation was observed on the cassette sheeting of five samples.Warpage was also observed on one cassette that had indentation.For three samples, visual inspection did not identify any abnormalities that could have contributed to the reported condition.Leak testing, clear passage testing, and clamp testing was performed with no issues noted with any of the returned samples.A simulated therapy was performed using all the returned samples, and it was noted that three of the returned actual samples completed testing with no issues.Five returned samples failed during the priming stage.Of the eight returned devices, the reported condition was verified for five samples.The reported condition was not verified for 3 returned samples.The cause of the indentations on the samples and warped cassette was determined to be manufacturing related.A batch review was conducted and there were no deviations found related to this reported condition during the manufacture of this lot.Should additional relevant information become available, a supplemental report will be submitted.
