The device was manufactured from may 20, 2020 ¿ may 21, 2020.One actual device was received for evaluation.The unit was returned containing approximately 124ml of fluid in the bladder.A visual inspection was performed on the unit via the naked eye which showed no evidence of fluid coming out at the distal end of the flow restrictor.Inspection on the flow restrictor revealed the cause of the flow problem was due to air bubbles blocking the fluid path inside the lumen of the capillary glass.The capillary glass is located inside the flow restrictor housing.No additional observations were found.The reported condition was verified.The cause was not determined, however, the potential cause of the air bubbles may be due improper filling technique during product use (filling step).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.
