E1: initial reporter address: (b)(6).H4: lot manufacture date: may 22, 2023 - may 23, 2023.H10: the device was received for evaluation containing 178ml fluid in the bladder.Visual inspection was performed on the returned device and there was no evidence of fluid flowing out at the distal end of the flow restrictor.A microscopic inspection on the flow restrictor revealed the cause of flow problem was due to a series of micro-air bubbles blocking the fluid path inside the lumen of the capillary glass located inside the flow restrictor housing.The reported condition was verified.The cause of the air bubbles inside the lumen of the capillary glass was most likely attributed to improper filling technique during product use (filling step).The product label (ifu, instructions for use) details the proper filling technique to avoid this type of occurrence.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.
