The following fields were updated due to additional information: d10: device available for eval yes.D10: returned to manufacturer on: 14-dec-2022.One sample was received by our quality team for evaluation.From the sample, a broken catheter was observed.The part-off surfaces on both ends were examined and a clean cut was observed.A review of the internal manufacturing device records and raw material history files for the reported lot number was performed and no recorded quality problems or rejections to this incident were found.The arterial cannula tube draw machine was reviewed.The machine parts that contact the catheter tubing were the machine grippers.However, the machine grippers have a round flat surface with no sharp edges that could cause part-off in the catheter tubing.The arterial cannula assembly machine was also reviewed.There is an automated vision inspection machine at the arterial cannula assembly machine which will auto-reject any parts not meeting the lie distance requirement.If the catheter tubing is broken, its lie distance would most likely have failed and will automatically be rejected by the line.A simulation was carried out by using scissors to part-off a catheter.The part-off surface was then observed.Based on this simulation, the broken catheter could have been caused by a sharp object such as scissors.According to the instructions for use (ifu), scissors are not be used at or near the insertion site.Therefore, the root cause could not be established.H3 other text : see h10.
