Correction b5: change quantity to (2) two units (previously reported as one unit.H4: the lot was manufactured on may 4, 2023 ¿ may 5, 2023.H10: two devices were received for evaluation.The units contained fluid in their bladder.A visual inspection with the naked eye was performed on the devices, which showed no evidence of fluid coming out at the distal end of the flow restrictors.A microscopic examination on the flow restrictors revealed the cause of the flow problem was due to a series of micro-air bubbles blocking the fluid path inside the lumen of the capillary glass.The capillary glass is located inside the flow restrictor housing.The reported condition was verified.The cause of the condition was determined to be user related due to the air bubbles inside the lumen of the capillary glass, which is caused by an improper filling technique during product use (filling step).The product label, instructions for use, details the proper filling technique to avoid this type 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.
