Additional information was added: the device was manufactured from august 5, 2019 - august 6, 2019.The actual sample was received for evaluation.Visual inspection was performed using the naked eye which revealed a clear particle, measured 0.20 square mm.The particle was not in the fluid path because it was embedded in the material of the tubing line.The particle was subsequently identified by fourier-transform infrared spectroscopy to be polyvinyl chloride (pvc).Pvc is a raw material of the tubing line.The reported condition of particulate matter was verified on the returned sample.The cause of the condition is related to a supplier manufacturing 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.
