H10: the actual device was received for evaluation.Visual inspection on the returned device via the naked eye noted evidence of leak at the fillport when the fillport cap was removed.Further inspection on the device revealed the cause of backflow was due to a particle measured to be 2.37 mm in length, stuck under the device checkband.The particle was identified to be acrylic material via fourier transform infrared spectroscopy (ftir) test.Acrylic is the material of the device stressmember.The reported condition was verified.The cause of the material under the checkband could not be determined; however, the most probable cause is related to small shaving getting stuck under the checkband during manufacturing.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.
