H10: one (1) actual device was received for evaluation containing fluid in the bladder.The other sample was not received and therefore, could not be evaluated.Visual inspection revealed a leak/backflow at the fill port when the fill port cap was removed.The cause of the leak/backflow was due to a particle lodged under the device checkband.The particle was subsequently identified to be acrylic material via fourier transform infrared spectroscopy (ftir) test.Acrylic is the material of the device stressmember.The reported condition of backflow was verified.The cause of the particle under the checkband could not be determined; however, the most probable cause was small shaving from the stressmember created during manufacturing which get stuck under the checkband.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.
