The lumbar catheter 910121 was returned for evaluation: device history record (dhr) review ¿ the device history records of ref 910121, lot 220762, were reviewed and did not reveal any anomaly that could explain the reported event.Failure analysis - two catheters were received with 3 damaged guidewires (kinked, see photos).One guidewire was received inserted in a catheter and exits at the catheter tip, which was indeed cut (as stated in the complaint).Inspection of the catheter shows the 2 series of drainage holes were indeed present, the closed tip was cut (not clean cut).The complaint stating that the catheter was not perforated at the end is not verified, the received catheter did include the drainage holes, per specifications.The catheter tip is closed to allow use of the guidewire for catheter placement.Cutting the tip the way the catheter was received does not allow the use of the guidewire for placement.Root cause - the device tested within specifications, no further investigation nor corrective action is deemed required.
