The following fields were updated due to additional information: d.10.Device available for eval?: yes.D.10.Returned to manufacturer on: 6/3/2020.H.6.Investigation: three representative samples were received by our quality team for evaluation.All 3 representative samples were visually inspected on the following: damage on the silicone tubing, burr/flashes on the catheter tip, damage on the catheter tip, kink on the catheter tubing, other defects on catheter tubing, foreign matter in fluid path.No abnormality was observed on any of the samples.After the above visual inspection, the needle grip assembly of the samples were removed, and the catheter was subjected to another round of visual inspection to inspect the sample categories.No abnormality was observed once again on all samples.3 of the catheter samples from the above inspection were sent for x-ray analysis to check if there any concentricity issues in the catheter tubing area.If one section of the interior of the tubing wall has a thinner wall, that section will kink more easily.No concentricity issues were observed throughout the tubing during x-ray scans.Floswitch button operations force inspection was carried out on all 3 of the catheter samples.All results were within specification.Flowrate testing and kink flow rate testing was conducted on all 3 of the samples.All results were within specification.The incident could not be verified.A review of the internal manufacturing device records and raw material history files for the reported lot numbers was performed and no recorded quality problems or rejections to this incident were found.Based on the investigation, no probable root cause could be determined due to no issues being observed.
