The device was received for evaluation.A visual inspection was performed, and it was noted that there were no signs of blockage inside the tubing line or the bladder.A functional flow test was performed, and it was noted that there was no evidence of flow observed coming out of the distal luer.Microscopic examination of the flow restrictor revealed the cause of the no flow problem was due to white crystallized drug blocking the fluid path at the distal end of the glass capillary.The glass capillary is located inside the flow restrictor.The reported condition was verified.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.
