The device was manufactured from august 27, 2019 - august 28, 2019.The actual device was received for evaluation.Functional testing was performed by filling the device with green colored water.During fill, leak/backflow was observed at the fillport.The reported condition was verified.Further evaluation revealed the cause of the leak/backflow was due to a particle measured to be 0.25 square mm in size, lodged under the device checkband.The particle was subsequently identified to be acrylic material via ftir spectroscopy (fourier-transform infrared spectroscopy).The cause was determined to be a manufacturing related issue.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.
